124 SPIDER ~ GENERAL INFORMATION
Platform: MAZDA/FCA joint partnership was established to share costs developing the 4ᵗʰ generation of N-platform roadsters (in both LHD and RHD configurations), since they were considered to be low-volume niche vehicles for both brands:
ND: 4ᵗʰ generation MAZDA MX-5 introduced for model year (MY) 2016 (one year earlier than the 124 Spider*), and still in production.
NF: FIAT and ABARTH iterations of 124 Spiders produced for MY 2017 through 2020; (in Europe, last MY was 2019, since the 1.4 L MultiAir engine was no longer capable of meeting newly-mandated stricter WLPT emissions regulations).
Assembly Plant: Hiroshima, Japan (MAZDA’s same plant that produces the ND MX-5); Note: ABARTHs with the “Heritage stripe” option, were first shipped to either Turin, Italy or Detroit, Michigan for that additional custom paint application, before continuing on to their final destination.
FIAT vs ABARTH:
ABARTH is a subsidiary of FIAT (technically now FCA Italy SpA) that focuses on the production of performance vehicles for race and road. FIAT produces the “base” versions of the vehicles upon which ABARTH versions are based. Note: In North America, since no dealer network existed for the ABARTH brand, they were marketed as a third “performance” trim level of the FIAT brand instead.
Drivetrain: Front-midship engine, rear wheel drive (RWD)
Performance:
Zero to 60 mph: 6.8 seconds
60 mph to Zero (Braking with standard wheels / tires / brakes):
→ →♦ Classica – 113 ft.
→ →♦ Lusso – 110 ft.
→ →♦ ABARTH – 104 ft.
Quarter Mile: 14.9 sec. @ 93.2 mph
Top Speed: 138 mph (144 mph for ABARTHs)
Drag Coefficient (Cd): 0.35 all models
Center of Gravity: 15.16 in. (38.5 cm)
Reliability:
Because the engine was improved upon during Dodge Dart production (2013-2016), the proven manual trans from the third generation (NC) of the MAZDA MX-5 was retained, and the rest of the vehicle was improved/proven by MAZDA during the MX-5 ND’s first year of production (2015; MY 2016), the 124 Spider’s overall reliability has proven to be excellent – the manual transmission models arguably surpassing the ND’s!

* Typical first-year build quality issues were resolved in 2015 during the MY 2016 MX-5 production, leading to an uneventful Summer 2016 launch (in regards to build quality issues) of 124 Spiders. The resolved issues included convertible top inner cloth and/or tension bands separating, low refrigerant leak from a poor-quality o-ring groove on the cooler pipe (high pressure side) at the expansion valve, and issues with the infotainment system version 55 firmware, including ⚫ Navigation or other screens freeze or reboot ⚫ Issues with Pandora Radio ⚫ USB device fails to start playing, resume or display music information ⚫ BT audio device fails when starting to play, resume or connect.
124 SPIDER ~ BODY & CHASSIS
Layout: Monocoque unibody platform ⇑ is designed to accommodate:
→ →♦ both LHD and RHD configurations, and the unique engines & body panels for either the 124 Spider or the MX-5
→ →♦ RWD powertrain assembly featuring power plant frame (PPF)
→ →♦ front and rear suspension sub-frames
Aluminum body panels ⇒: Hood, front quarter panels, and decklid (for both the 124 Spider and the MX-5)
Other aluminum components ⇒ (for both the 124 Spider and the MX-5): front bumper reinforcement, chassis tunnel braces, power plant frame (PPF), differential casing, roll bar, rear bulkhead panel, rear bumper reinforcement, interior access panel, roof frame & header panel, wiring loom, front wishbones, belly pan, and wheel uprights. Also, the luggage rack (OEM with FIAT 124 “America” only; otherwise optional MOPAR # 52060660).
Chassis construction: High-tensile strength steel
Steel body panels: Doors, rear quarter panels, narrow panel just ahead of decklid (for both the 124 Spider and the MX-5)
Soft-top well drains/ Door drains: Don’t forget to keep the soft-top well drain filters, as well as the door weep holes in working order.
Magnetic CB antenna capability: yes, on horizontal surface of either rear quarter panel (non-existent on ND MX-5)
Windshield: OEM “Lamipane” windshields (for both the 124 Spider and the MX-5), are all manufactured in Osaka, Japan by Nippon Sheet Glass (NSG)/Pilkington. See my article for replacement details
Window tinting notes: article
Heated glass/side mirrors: although all models have a heated rear window (defrost), heated side mirrors are optional (Lusso), but since the wiring, switch and fuse already exists, you can purchase parts and install (see forum articles 1 and 2)
Carbon Fiber composite: Removable hardtop roof (OEM with ABARTH 124 GT only)
Hardtop Mounting Tab Covers: From the owner’s manual for the GT Hardtop kit, I’ve put together an illustration that shows how the cover plates adjacent to the trunk lid are attached/removed/installed ⇓
Trim fasteners: nylon push-type retainers used throughout vehicle and nylon clips for door trim panels
Front Tow Hook Cover (replacements):
→ →♦ Classica & Lusso: MOPAR # 68333157AA
→ →♦ ABARTH: MOPAR # 6KF49TZZAA
Front Tow Hook (Steel) ⇒: MOPAR # 68315340AA; should normally be found with tire-repair kit in trunk; fits either front or rear location (the shorter rear tow eye is usually recycled, but the occasional dealer tossed that in the trunk too)
Lifting Locations (with hoist or low-profile jack and slotted jack pad); more details
⚫ red = jack locations with slotted pad ⚫ light blue = 2-post hoist lift with arms ⚫ dark blue = jack stands (either front or rear), after lifting with jack **ameridan**
124 SPIDER ~ IGNITION START/STOP SWITCH
Ignition Switch ⇒: MOPAR # 68314297AA
Instructions (need key fob within operational range):
Ignition Push Button Switch without pushing clutch pedal (MT) or brake pedal (AT):
Each time the keyless ignition START/STOP button is pushed, the ignition cycles in the order of OFF, ACC, ON, and back to OFF mode, without the engine ever starting.
Ignition Push Button Switch while pushing clutch pedal (MT) or brake pedal (AT):
Each time the keyless ignition START/STOP button is pushed, the engine cycles in START or OFF mode.
Instructions, if key fob battery is dead (or if room fuse is not in place): Starting the car by pushing the “Start/Stop” button by pressing it with the fob (rather than your finger), is how the cars are moved around in “transport mode”, before the room fuse has been installed. There is a RFID chip in the fob that can be detected by the switch, and if the code is correct, will allow the engine to be started. Keep that in mind in case someone has been working around the fuse panel under the hood and your car can’t detect the key.
124 SPIDER ~ ENGINE SPECS, REQUIREMENTS & CAPACITIES:
go directly to:
fuel & emissions oil cooling/coolant
Note: The Engine Control Module is the one non-Mazda module not shared with the Miata, is produced for FIAT by Delphi in several regional iterations, and is most commonly referred to as the ECM.
Engine: Our FIAT/Alfa Romeo 1.4 Liter, 16-valve, turbocharged, Multi-Air*, in-line four-cylinder (I-4) with multi-point fuel injection (MPFI) and variable valve timing (VVT) engines were all robot assembled & shipped from Termoli, Italy (not at Dundee, Michigan). It’s a good thing the engine block was first used in the Alfa Romeo Mito <2008-2016>, FIAT Punto <2007-2014> and Dodge Dart <2013-2016> (all FWD cars), as additional oiling channels were added in the walls of the #2 and #3 cylinders in 2014, to resolve forced-induction lubrication issues. The RWD 124 Spider is the first (and only) longitudinal installation application of this engine, requiring additional changes to the manifolds, oil pan + dipstick, vacuum pump, timing cover, intercooler, mounts, and engine cover.
Displacement: 83.48 cu. in. (1,368 cc)
Bore x Stroke: 2.835 in. x 3.307 in. (72.0 mm x 84.0 mm)
Bore-Stroke Ratio: 0.86:1
Cylinder Firing Order: 1 • 3 • 4 • 2 (# 1 is closest to the radiator, @ timing belt end of engine)
Timing Belt, Tensioner & Water Pump Kit: Mopar # 68466921AA ⇑
Timing Belt (EPDM serpentine) Change Interval: 150,000 miles (240,000 km) or 15 years (whichever comes first); source ⇓ (European manual shows 120,000 km in error)
Pete124 suggested: A potentially useful trick to avoid using special tools normally required for this belt change to lock the cam/crank (and subsequent TDC sensor calibration for the ECM by re-initializing via a “phonic wheel learning procedure”) is to slice the old belt in half longitudinally while still in place and remove the outer half. Slide the new belt on to the exposed cogs then cut the old belt away and push the new belt fully home (this means the water pump isn’t getting replaced though). Thoughts?
Accessory Drive Belt Change Interval: 80,000 miles (128,000 km)) or 8 years (whichever comes first); if driven in dusty areas, change sooner
Intake Valve System: Instantaneous, fully variable intake valve lift and timing control of the 8 intake valves by belt-driven, Multi-Air* hydraulic actuator “brick”, replacing the overhead camshaft used in the T-jet version of this engine
Intake Valve Lobe Lift (max): 0.370 in. (9.3 mm)
Exhaust Valve System: Single overhead camshaft that operates the 8 exhaust valves directly through inverted bucket tappets
Exhaust Valve Lobe Lift: 0.295 in. (7.5 mm)
Construction: Aluminum-alloy head and bed-plate; cast-iron block (details)
Compression Ratio: 9.8:1
Weight-to-Power Ratio: 15.2 lb./HP (vs 15.0 lb./HP for the MX-5)
RPM Limiter: ECM limits max. to 6,250 rpm (and 3,000 rpm, if AT is in Park/Neutral)
“Too-Cold” Disable: Pre-start clicking noises? Relays triggered by ECU logic based on ambient (and oil) temperatures that enable the starter only if the temperature is above -22° F (-30° C); If you’d like to increase the cold-start range to -34°F, I suggest you consider adding a block heater (details)
Air Filter Change Interval: 30,000 miles (48,000 km) or 3 years (whichever comes first); if driven in dusty areas, inspect at every oil change, and change sooner, as warranted; source
Air Filter: MOPAR # 68335718AA is the specified replacement, however note that MAZDA installs as OEM, their PEES-13-3A0 filter (same as in the ND MX-5); equivalent substitutions can also be used, like WIX WA10424; for additional replacement guidance: Pictorial air filter change ♦ Air filter change video
Spark Plugs (4): NGK SIKR9A7 Laser Iridium mfd. with a generic 0.027 – 0.028 in. pre-gap (the more expensive MOPAR # SP070507AC and FIAT RICAMBI # 55244561 are the same plugs); a close “unofficial” alternative in U.K. (if unable to obtain spec plugs) is NHK DCPR9EIX (mfd. with a 0.032 in. pre-gap though).
→ →Note: The plug gap needs to be set ⇓ before installing!
Spark Plug Gap Spec: 0.023 – 0.027 in. (0.6 – 0.7 mm) per FIAT Service Manual, however Eurocompulsion recommends 0.023 – 0.024 in. especially for hi-perf. tunes, to prevent misfires at high revs. (in fact, the plugs they sell have been set to 0.023″ prior to shipping 😉 )
→ →♦ For those that don’t monitor the gap, it is highly recommended that you set the gap to 0.023 – 0.024 in., so that it is unlikely to later deteriorate outside spec range.
→ →♦ Avoid contact with the iridium center electrode as much as possible!
Spark Plug Change Interval: Although this is normally a 100K mile plug, FIAT recommends replacement at 30,000 miles (48,000 km) or 3 years (whichever comes first); source (actual real-life experience points to ≈ 25,000 miles, regardless of age)
Spark Plug Socket: 5⁄8 in. (need to remove cover and remove ignition coil packs first)
Spark Plug Torque: 13.5 ft.•lb. (18 N•m) per the manual; Note: oil and compression can slip by the spark plug threads, if the crush washer isn’t properly compressed. Tork Motorsports insists that a proper torque should be 21 ft.•lb. (28 N•m) to nullify this from occurring.
Ignition Coil Packs (4): MOPAR # 68320163AA are OEM;
Notes: helpful video; Bosch # 0221504715 are good OEM alternatives; coil wiring diagram; procedure for replacing coil pack connector because of broken locking tab.
Wrench size for Ignition Coil Pack Mounting Bolts: 10 mm
Ignition Coil Pack Mounting Bolts Torque: 6.6 ft.•lb. (9 N•m)
Engine Mounts: Although the lower mount “perches” have a Mazda logo on the casting, do not order these parts from Mazda; details
Engine exchange note (thanks Calehedron): an engine mated to an automatic has a bell housing plate, vs. a 2-piece thin cover assembly and flywheel/clutch, when mated to a manual.
Re-calibrate Throttle (required after any ECM alterations):
→ →♦ Ignition ON (not ACC; more)
→ →♦ Press accel pedal to the floor 5X (within 10 seconds)
→ →♦ Ignition OFF (for another 10 seconds)
Turbocharger:
→ →♦ MOPAR # 4892938AE
→ →♦ Garrett GT 1446 (much more robust than the IHI RHF3 turbo in the T-jet engine)
→ →♦ Maximum Boost: @ 230,000 RPM; ECM limits max. boost to 22 psi / 2.49 bar; (great article on FIAT boost control)
Turbo Diverter (Surge) Valve: MOPAR # 4892991AA
Allen Wrench size for Diverter Valve Mounting Bolts: 5 mm
Turbo Waste Gate Solenoid: MOPAR # 4627297AB
Power, a.k.a. horsepower (HP):
→ →♦ Classica & Lusso: (SAE) 160 HP (119 kW) @ 5,500 rpm
→ →♦ ABARTH: (SAE) 164 HP (122 kW) @ 5,500 rpm
Notes: ABARTH’s extra 4 HP is a result of less exhaust resistance because of both the larger diameter exhaust crossover pipe, and the lack of a resonator in the mid-pipe; European engines are not tuned differently – the reason that Europe HP are stated differently is simply because instead of using SAE HP units, they use metric HP.
Torque:
Classica, Lusso & ABARTH (normal mode):
→ →♦ 169 lb.•ft. (230 N•m) @ 2,500 rpm
→ →♦ 184 lb.•ft. (250 N•m) @ 3,200 rpm
ABARTH (sport mode): 184 lb.•ft. (250 N•m) @ 2,500 rpm
Fuel & Emissions:
Fuel System: Sequential, multi-point, return-less, electronically controlled fuel injection
Fuel Grade Usage:
→ →♦ 87 octane acceptable
→ →♦ 91 octane recommended, especially for temps > 85°F
→ →♦ Note: Hi-perf. tunes mandate using 91 octane
Fuel Tank Capacity: 11.9 U.S. gallons (45 liters)
Fuel Pump Pressure: Regulated @ 58 PSI
Fuel Injectors (4): MOPAR # 4627652AB (Alfa Romeo # 55241175) are OEM; flow rate @ OEM pressure: 38.46 lbs/hr (404 cc/min); USCAR connectors; Bosch # 0 280 158 300 (thanks Calehedron)
Air Oil Separator (AOS) Servicing Interval (also PCV Valve): 30,000 miles (48,000 km) or 3 years (whichever comes first); sooner if:
→ →♦ an “oil leak” around cylinders #3 or #4 is suspected
→ →♦ 10,000 miles (16,000 km) for “severe” driving, which includes frequent short trips, driving in hot weather, stop-and-go traffic, track use, and driving through mountainous passes.
→ →
Note: nice video showing how to clean and re-use the AOS, rather than replacing with new, however the PCV valve should be replaced with new.
PCV Valve: MOPAR # 4893073AA (or equivalent, such as Duralast PCV1010DL). Mopar will claim this part isn’t compatible, wanting you to buy a new AOS instead.
Oil Catch Can(s): If you are considering installing catch can(s) to reduce the amount of oil found in your air filter (potentially entering the turbo air intake and/or throttle body), first try simply replacing the PCV valve. Some helpful tips can be found in this forum thread (summarized in my markup of 17221′s photo ⇑ (or if you’re considering a dual catch setup, illustration).
Emission Controls: 3-way catalytic converter, heated oxygen sensors, and no EGR valves – thanks to the precision of Multi-Air* control of intake valves, resulting in CO² emissions of .66 lb./mile.
Oxygen (O²) Sensors: Upstream (#1) MOPAR # 68235253AB; Downstream (#2) MOPAR # 68235254AB; recommended special offset 22 mm socket to prevent damage to wiring, and accessibility.
Oxygen Sensor Torque: 26 ft.•lb. (35 N•m)
Lose a yellow connector locking tab?: See comment 13
Emission Control Components Warranty (U.S.): Per Federal law, the ECM, OBDII and catalytic converter are covered for the first 8 years / 80,000 miles (whichever first occurs).
Emissions Testing: If you fail a mandated emissions test for one or more of the ECU monitor systems reporting “not ready”, check out the likely reasons and “generic OBD drive cycle” instructions.
EPA Fuel Economy (U.S. city/highway/combined):
→ →♦ 26/35/30 mpg with 6-speed manual transmission
→ →♦ 25/36/29 mpg with 6-speed automatic transmission
Highway Range (manual / automatic): 416.5 miles / 428.4 miles
MotorTrend “Real Fuel Economy” (U.S. city/highway/combined):
→ →♦ 30.4/43.4/35.1 mpg
Oil & Oil Filter:
Oil Grade Required:
→ →♦ SAE 5W-40 Full Synthetic API Certified, FCA MS-12991 or
→ →♦ FIAT‘s European equivalent 9.55535-S2 or
→ →♦ ABARTH‘s equivalent 9.55535-GH2 or
→ →♦ MOPAR # 05127394PC
→ →♦ or an equivalent, such as:
-
- Pennzoil Platinum Euro Full Synthetic 5W-40 ($ rebate $) ♦ this is the same oil that the FIAT factory in Dundee, Michigan fills each new 1.4 L engine with (not ours produced in Termoli, Italy though), and is the design standard (see Note 2)
- Quaker State Euro Full Synthetic 5W-40 (Shell Helix Ultra 5W-40, more commonly available in Europe ♦ MotoMaster Full Synthetic 5W-40, produced by Shell for Canadian Tire ♦ and this Quaker State, are all likely relabeled Pennzoil Platinum Euro oil, as parent company Shell owns these brands)
- Total Quartz 9000 Energy 5W-40
- Motul 8100 X-Cess Gen2 5W-40
- Ravenol VST 5W-40
- MPM 05000C3 5W-40 Premium Synthetic C3
- Havoline Pro-DS 5W-40
- Redline Euro Series Full Synthetic 5W-40
- Petronas K P.E. 5W-40 (certified to meet FIAT 9.55535-S2 ♦ more commonly available in Europe ♦ this is the same oil that the FIAT factory in Termoli, Italy fills each new Classica & Lusso engine with
- Petronas Selenia ABARTH 5W-40 (certified to meet FIAT 9.55535-GH2 ♦ more commonly available in Europe ♦ also available labelled as Petronas Selenia Quadrifoglio 5W-40 ♦ this is the same oil that the FIAT factory in Termoli, Italy fills each new ABARTH engine with
- AMSOIL FS Synthetic European 5W-40 (AMSOIL has not sought FCA certification, but officially guarantees that this oil is also a suitable alternative)
Note 1: 0W-40 is an ideal cold-climate alternative to 5W-40 – having a thinner “cold” viscosity. Although Mobil has not sought FCA certification, they officially guarantee that their Mobil 1 ESP X3 0W-40 oil meets or exceeds FIAT 9.55535-S2. I only mention this since, the others listed above may not be easily obtainable in some countries, and since some FIAT dealers in cold-climate regions are using Mobil 1, it is doubtful that FCA would fight this choice, should an oil related issue occur during the warranty period.
Note 2: The ECU has the oil temperature/viscosity parameters for the entire working temperature range of Pennzoil’s Platinum Euro oil, programmed in, because in addition to lubricating your engine, the oil also plays a major function within the Multi-Air brick in individually controlling all of your intake valves, so other than the grade difference mentioned in Note 1, it is imperative that you adhere to the specified oil requirements, and not just find any ‘ol 5W-30 or 5W-40 oil that is convenient! (quite likely in some quick-lube shops). Regarding 5W-30, viscosity is ultra important and the viscosity of this oil can cause the cam/valve operation to misbehave!
Multi-Air “brick”
* Multi-Air: Hydraulically-actuated ⇒
variable valve timing (VVT) engine technology (upgrade from the T-jet version) enabling “cylinder by cylinder, stroke by stroke” control of intake air directly via the engine’s inlet valves (great article on FIAT’s Multi-Air technology)
Oil Pressure (@normal operating temp):
→ →♦ @ curb idle: >10 psi
→ →♦ @ 4,000 RPM: >58 psi
Oil Capacity: Although the manual states 4 qts. with 
dry filter (3.785 liters), an initial fill of 3½ qts. is advised, to avoid having to extract potential overfill; add as necessary after running engine for a few moments (also good opportunity to inspect for O-ring seal leaks of the oil filter cap and drain plug)
Oil Drain Plug: MOPAR # 6507741AA with re-usable O-ring, not crush washer; M14 x 1.5
Oil Drain Plug Torque: 14.75 ft.•lb. (20 N•m)
Wrench size for Drain Plug: 13 mm (1⁄2 in.)
Wrench size for (9) Belly-Pan Bolts (to expose drain plug): 12 mm (15⁄32 in.)
Replacement Belly-Pan Bolts: MOPAR # 68314616AA (M8 x 1.25 x 16 to 22 mm long flange bolts)
Belly-Pan Bolts Torque: 71 – 80 in.•lb.
Oil Filter Cartridge (includes new O-ring for cap): MOPAR # 68102241AA, or equivalent
Oil Filter Cap (w/ Bypass Valve): MOPAR # 04892850AA (normally, no need to replace)
Oil Filter Cap Torque: 18 ft.•lb. (25 N•m) per Service Manual, but after it bottoms out, using the wrench, you risk distorting the O-ring
Wrench socket for oil filter cap: 27 mm (1 1⁄16 in.)
Oil (& Oil Filter) Change Interval (first to occur with “normal” driving):
→ →♦ ≈ 1 year or
→ →♦ ≈ 10,000 miles or
→ →♦ when the oil-life monitor indicates “Oil Change Due!”
→ →Note that the oil-life monitor should react to “severe” driving by alerting the driver much sooner than 10,000 miles (perhaps closer to 3,000 miles). This includes frequent short trips, driving in hot weather, stop-and-go traffic, track use, and driving through mountainous passes.
→ →(DIY instructions via drain plug + via dip-stick tube extraction)
Reset Oil Change Monitor (also, an illuminated Wrench light (near tach’s 4,000 rpm position), but only if “oil change” is what triggered the light (not “tires” or “other scheduled maintenance”):
→ →♦ Ignition ON (not ACC; more)
→ →♦ Press accel pedal to the floor 3X (within 10 seconds)
→ →♦ Ignition OFF
➤ Regardless of wrench light status, reset Oil Change Monitor after each oil change!
Other oil related items, not associated with standard oil changes:
→ →♦ Multiair-Brick Oil Filter Banjo Bolt: MOPAR # 68189847AA (more details)
→ →♦ Turbo Oil Filter Banjo Bolt: (more details)
Engine Cooling & Coolant:
Although MOPAR # 68163848AB Antifreeze / Coolant was specified in the owner’s manual, FIAT is now (2018) recommending MOPAR # 68334695AA Antifreeze / Coolant, or equivalent FL22 coolant, as specified on the coolant reservoir cap, and matching the coolant that MAZDA installs (including the green color).
For more details, read my in-depth article.
Note: If flushing the coolant out, I recommend switching over to the aforementioned purple, “Extended Life” MOPAR coolant {or equivalent} + reflect that changeover on the coolant reservoir bottle cap label.
Coolant Capacity:
→ →♦ 7.6 qts. (7.2 liters) with six-speed manual
→ →♦ 7.5 qts. (7.1 liters) with six-speed automatic
Coolant Change Interval: 5 years or 75,000 miles (120,000 km), whichever comes first. Note: Since the FL22 spec coolant is “5-Year POAT (Phosphate Organic Additive Technology)”, and therefore isn’t an “Extended Life” coolant, I disagree with the Owner’s Manual which states 10 years or 150,000 miles (240,000 km)
Coolant leaking?: Although the water pump is usually suspected, the core plug (MOPAR # 6106046AA) may actually be the culprit (more here), or it could simply be the expansion tank overflow venting
Cold-Engine (blue) light: simply indicates coolant temperature hasn’t yet reached 130° F (54.5° C); not to be considered a warning, but rather a “don’t bother turning on the heat yet, it wont work” light.
Hot-Engine (red) light: warning that coolant temperature is at least 223° F (106° C )
Normal Operating Temperature Range: 170°F – 195°F
Thermostat: MOPAR # 68320858AA; the 124 Spider is the only FCA vehicle that uses this particular electrically assisted (also called “map-controlled”) thermostat that provides broader and faster operation than traditional thermostats. Rather than depending on coolant temperature alone, electric coils heating the wax inside the thermostat are controlled by the ECU to schedule optimal opening, factoring in the current load demands on the engine. If the time to reach operating temperature falls outside of the algorithm, resulting in a CEL, try increasing the engine load temporarily by activating the A/C after starting.
Thermostat initial opening temperatures:
→ →♦ Globally (except U.S. and Canada) ~ 188° F – 193° F (86.5° C – 89.5° C)
→ →♦ U.S. and Canada ~ 177° F – 182° F (80.5° C – 83.5° C)
Water Pump: MOPAR # 68385387AA (common on all Fiat/Alfa Romeo 1.4 L engines)

124 SPIDER ~ MANUAL TRANSMISSION
Availability Standard: Classica, Lusso, ABARTH
Make / Model #: MAZDA C635 (some sources state MAZDA P66M-D?)
Description: Six-speed; 1ˢᵗ, 2ⁿᵈ, 3ʳᵈ, 4ᵗʰ gears: Triple cone
Prior usage: MAZDA developed a different MT for the ND MX-5 (Model M66M-D, 15 lbs. lighter, and much lower torque capability primarily due to housing flex attributed to removal of ribs) that FIAT chose to avoid, and instead use the same internals as version used in NC3 MX-5, although the housings differ slightly to accommodate shifters and mounting to respective engines. NC Service Manual for reference; per Good-Win Racing, clutch is not NC spec though.
Adjustment procedure: described in detail, should it pop out of 4ᵗʰ gear.
Rating: 258 lb.•ft.

124 SPIDER ~ OPEN DIFFERENTIAL
Availability Standard: Classica, Lusso (both MT & AT)
Make: GKN Driveline (Tochigi Fuji)
Description: Torque-sensitive cone type, helical gears, open center – meaning that effectively the torque is evenly split among the two wheels, but that can result in the drive of the engine being sent to the wheel of least resistance
Wrench socket for filler plug: 23 mm
Wrench socket for drain plug: 24 mm
Filler and drain plug crush washers: Mopar # 68314601AA (thanks DBoe)
Fluid Requirement: MOPAR # 68333589AA, or a 75W-90 SG1 (GL-5) Hypoid Gear Oil equivalent; (DIY instructions)
Fluid Capacity: 0.63 qt. (0.6 liter)
Axle Ratio: 3.454:1 with manual / 3.583:1 with automatic
Notes: Cross-compatible with ND MX-5 (although different internals result in a 2.866:1 axle gear ratio with manual / 3.45:1 axle gear ratio with automatic, so performance would be altered); 15 lbs. lighter than the NC MX-5 differential.
Availability Standard: ABARTH (both MT & AT)
Make / Model: GKN Driveline (Tochigi Fuji) / Super LSD
Description: Torque-sensitive, cone clutches made of hardened metal which can transmit higher torque levels for a given diameter than traditional flat plate clutches
Axle Ratio: 3.454:1 with manual / 3.583:1 with automatic
Torque Bias Ratio (TBR): 1.8:1 (represents maximum distribution ratio of torque from side to side)
Wrench socket for filler plug: 23 mm
Wrench socket for drain plug: 24 mm
Filler and drain plug crush washers: Mopar # 68314601AA (thanks DBoe)
Fluid Requirement:
→ →• 4 oz. of MOPAR # 68334697AA, or a FCA MS-10111 Limited Slip Additive equivalent (a friction modifier)
→ →• and remaining capacity with MOPAR # 68333589AA, or a 75W-90 SG1 (GL-5) Hypoid Gear Oil equivalent
(Note that some equivalent ‘limited slip’ gear lubes, may already contain the required friction modifier, but I don’t believe the spec’d lube is on-it’s-own, a limited slip gear lube. The Fiat Service Manual states that the additive is required for LSD, but I think the note “Additive is contained within the specified gear oil for the rear differential” is a misinterpretation of the fact that the additive is to be added to the MOPAR # 68333589AA gear oil, not that it is already mixed in.)
Total Fluid Capacity: 0.63 qt. (0.6 liter)Notes: Cross-compatible with ND MX-5 GT (although different internals result in a 2.866:1 axle gear ratio with manual / 3.45:1 axle gear ratio with automatic, so performance would be altered); Conical friction elements enveloping the side spider gears, with centrally-positioned springs to preload the friction surfaces.
124 SPIDER ~ ELECTRICAL SYSTEM
Alternator: Denso SC2 150 A with LIN regulator
OEM Battery: MAZDA‘s “Start-Stop” EFB battery (Panasonic enhanced flooded cell lead-acid); MAZDA part # PE1T-18-520-9U; Q85, 520 CCA, 65 Ah [20 hr rate], 52 Ah [5 hr rate], 37.3 lbs (16.9 kg), more details
Replacement Battery: As an alternative to the spec battery, FIAT has recommended that U.S. dealers install their stocked H5 battery (currently MOPAR # BB0H5500AB), which fits OK, although slightly smaller in height and capacity (500 CCA). See my battery article for other BETTER alternatives, which include good-value and readily available Group 35 (and Group 51R) batteries, unlike the Q85.
Battery Cover: Anclar has confirmed that the corrugated/insulated surround “battery guard” (Mopar # 68313904AA) also fits nicely with Group 35 replacement batteries. Do not discard, as it should be reused, in order to protect the battery from turbo/engine radiant heat.
Important: The ⊝ negative* or ⊕ positive terminal should always be disconnected from the battery, prior to working on any electrical/electronic components:
→ →♦ Tap the brake pedal for a few seconds afterwards, to completely discharge residual power
→ →♦ A 10 mm deep socket works to loosen the battery tie-down nuts, as well as the lead-post terminals.
→ →♦ Get yourself a battery carrier strap beforehand, since there is no built-in handle on the original battery (and perhaps your new battery) to lift it out of the car.→
→ →♦ Afterwards, upon re-connection, all modules learn current configurations, but you should re-initialize the windows and TPMS
→ →♦ Additionally, upon re-connection (and after a timing belt change), the UK/Euro owner’s manual indirectly mentions that the TDC sensor calibration for the ECM should be re-initialized via a “phonic wheel learning procedure” ➤ Let the engine run until the Cold-Engine (blue) light turns off – rev the engine min. 3 times up to 6000 rpm and let the RPM drop to idle in between – wait one minute, turn engine off, wait one minute, turn it on, wait one minute – this should store the phonic wheel values, and prevent getting intermittent misfire errors (including P0300/P0302/P0303), triggering the “Check Engine” light. (I doubt that this normally needs to be done just because the battery has been disconnected)
* The sensor module (MOPAR # 68340388AA) attached to the ⊝ negative terminal is somewhat fragile. Installing terminal with the customary hammer tapping may cause damage, resulting in alternator not charging and warning message >> I suggest you tap the terminal down using a larger diameter socket directly in-line with the lead post.

124 SPIDER ~ AIR CONDITIONING
Note: If you’d like to avoid musty smells emanating from the HVAC system, always allow the system to ventilate by turning Max & Recirculate OFF before parking the car overnight or longer.
Refrigerant Type: HFC134a (R-134a, aka as Freon™ 134a, a hydrofluorocarbon (HFC) refrigerant) is specified in my MY 2017, but at some point switched over to HFO-1234yf (aka Opteon™ YF, a hydrofluoro-olefin (HFO) refrigerant) instead, and that is what MOPAR now “officially” recommends, as it is claimed to be a compatible alternative (that meets EU standards), with “improved performance” and more environmentally friendly (although it is mildly flammable and does require special handling). Refer to the label on the underside of your hood (also specifies the PAG compressor lubricant that needs to be added), and if you aren’t in Europe, and your AC shop still uses R-134a, you need not change over.
HVAC “Cabin” Filter: MOPAR # 68313632AA or MAZDA N243-61-B05; it’s primary purpose is to protect foreign material from interfering with the fan, rather than filtering cabin air. The process for accessing this filter is quite involved, so contrary to the Owner’s Manual, which states mandatory replacement every 18,000 miles (every 3rd oil change; resulting in MOPAR’s excessively high fee for this service), FIAT has now agreed that this filter should not normally need to be changed, unless air flow seems restricted. Filter access procedure here. Note: If debris (or critters) seems to be an issue, consider adding a screen to the air inlet.
Evaporator Drain: If anyone happens to find water residing in their floor carpeting, I would first suspect the drain filters for the convertible top well are in need of cleaning, but a second possibility is a clogged/pinched drain hose for the HVAC evaporator. I couldn’t find out anything about this in either the Miata of 124 Spider Service Manuals, but justanothermx5 shared the results of his investigation, and has located the elusive HVAC drain connection (yes, it’s under the subwoofer/wedge, as shown in his photo above), where the hose going through the firewall is attached, allowing condensate to drip on the ground. If that hose somehow gets clogged, condensate can back up into the passenger footwell instead, so I’m displaying his pic, to hopefully help you locate the exterior end of the hose, as it would be advantageous to unclog it there (once you locate it), vs. breaking the seal by removing the drain component from the inside.
Cracked “cooler pipe” (HI): According to this revised Mazda TSB, if your A/C does not blow cold air, engine vibration may have cracked the weak spot in the under-designed cooler pipe. To correct this issue, the material and thickness of the cooler pipe replacement (now in it’s third generation, as noted by the B suffix in the part #) has been changed to increase durability (pipe diameter has been changed from 12mm to 16mm).
Note the additional comment: This repair with P/N NA6W-61-466B will only be covered once under warranty for MX-5’s that have suspension modifications and/or engine modifications such as PCM calibration, supercharger/turbocharger setup, engine mounts, headers etc.

Convertible Rollover Protection: Primarily attributed to the use of high-strength steel in the A-pillar structure surrounding the windshield. The high seat backs paired with the fixed aluminum roll-bar hoops (shown exposed in photo ⇒ of a ND MX-5), offer a little more protection. Brian Goodwin adds, “Stock hoops are designed to hold up for low-speed flips, like an intersection accident where you get pushed into the curb and roll over it. They are not designed for high-speed rolls, like going over an embankment or off a canyon road at speed. That’s why most track groups want to see a real roll bar [installed when participating] in higher-speed events.”
124 SPIDER ~ WHEELS, RIMS AND TIRES
Common specs for all OEM wheels (including ND MX-5; not 124 RALLY):
Quantity: 4 (no spare wheel)
Wheel Rim Bolt Pattern: 4 x 100 PCD 
Wheel Rim Offset (ET): +45 mm (positive offset, aka wheel inset) ⇒
Center Bore: 54.1 mm (wheels are primarily hub-centric, so if aftermarket wheels with a larger center bore are used, the correct size hub centric rings are recommended, but not required ➤ proper incremental lug nut installation procedure is even more critical though
Axle Nut clarification: If removed to install spacers, a new nut should be used, and torque spec should read ♦ 92 ft.•lb., -180°, 188 ft.•lb. (125 N•m, -180°, 255 N•m)
Rear Wheel Hub Assembly (same for left and right side): Fiat Part # 6000612251; Mopar # 68313912AA; Mazda # N243-26-15X; all quite expensive as the assembly includes wheel bearing, hub, studs and ABS magnetic ring. Aftermarket alternatives (thanks Victor Do):

🔴 Speedometer Calculations: The Revolutions/mile (/km) spec PID is programmed into the PCM for the OEM tires originally installed, and is the basis of all the vehicle speed calculations using input from the ABS sensors. The PID can not be changed to accommodate newly installed tires of a different circumference (nor even tread wear), so your speedometer readings may be slightly off.
124 SPIDER ~ TIRE PRESSURE MONITORING SYSTEM (TPMS)
🔴 Classica & Lusso (MY 2017, 2018) uses ABS algorithms to detect wheel rotational speed Δ; no actual TPMS sensors are in the wheel rims.

* Data source TireRack.com; values are adjusted to reflect representative rolling radius. Manual calculation results may differ, using equation [63360/(πΦ)], where Φ is the tire’s unloaded diameter (inches), since Revolutions per mile of a mounted tire under load will generally be about 3% more than the calculated number. These are most likely the numbers programmed into the PCM, for converting ABS wheel revolution data into Vehicle Speed.

Passenger volume: 49 cu ft (vs 48 cu ft for the MX-5)
Seating Capacity: 2
Seat Travel: 8.3 in. (210 mm) driver / 6.7 in. (170 mm) passenger
Seat Back Angle: 25° nominal, 12° forward, 22° rearward
Seat Construction: The seats in our Spiders are relatively lightweight (around 30 pounds due mostly to the steel frame). All of the comfort and support in both the seat bottom and seat back is attributed to the combination of the outer covering and the tight mesh fastened along both sides of the frame underneath that skin (there are no typical springs, and except for the bolsters – no foam).
Other than the outer coverings, the construction is exactly the same – whether they are:
- Classica’s premium cloth seats
- Lusso’s Italian Nappa leather seats
- ABARTH’s premium cloth, Nappa sport leather options or the Nappa leather with Alcantara suede (microfiber) inserts used in the Recaro seats
In my opinion, not only are the Classica seats the most durable, they are also the most comfortable, especially in extreme high and low temperatures (which may be why seat warmers needed to be made available for the leather seats). Granted, the other seats do have a premium appearance though.

Note: Since the Adaptive Front Lighting System (AFS) headlights have to point with a bias toward the inner edge of the road so as not to “blind” oncoming traffic, depending on the region, if ordering replacement units, be sure to order the proper LHD or RHD configuration, at least in Europe (thanks hefbadr). 
These lights self-level when starting the vehicle, and they move in conjunction with the steering wheel (really noticeable in foggy weather). When driving in countries that differ from your LHD/RHD configuration, the CMU personalization settings allow for unbiased aiming (straight-ahead) by switching AFS off temporarily (not sure why the UK manual omitted this).

* Notes regarding DRL:
→ →♦ The Daytime Running Lights (inboard of the LED halos) turn on automatically when the vehicle starts moving, and turn off when the parking brake is engaged or the gear selector is shifted to the PARK position (if equipped with automatic transmission). The CMU personalization settings allow for disabling DRL in some regions. Pictured is a U.S. AFS headlight, as it has an amber side-marker light lens.
→ →♦ Also note the headlamp [high-pressure] washer nozzle, required in Europe for lights producing ≥ 2,000 Lumens (the LED headlights), that are activated at every fifth windshield washer activation (thanks Steele).
→ →♦ A lower voltage is supplied to the Halogen bulbs for the DRL mode, so obviously the Lumen output is also reduced (vs High-Beam output).
Front Turn Signal Lights {2}: WY21W, SAE 7443NA (21 Watts, amber incandescent); lamp assemblies made by Stanley for the 2014–2018 Mazda3 are utilized (much more expensive to purchase as a FIAT part)
Front Foglamps (optional) {3}: H11 (Halogen, 55 Watts, 1345 Lumen, 6000 Kelvin); recommended bulb upgrade; lamp assemblies made by Koito Lighting for the 2014–2018 Mazda3 are utilized (much more expensive to purchase as a FIAT part). Note: although wiring exists for these foglamps in all models, without the Euro turn signal stalk (has switches for both front and rear foglamps), and perhaps a missing relay, just installing lamp assemblies will not enable their functioning, unless wiring modifications are done, as explained in a nice writeup for adding front foglamps to Classica here.
Rear Side-marker Lights {4}:
→ →♦ FIAT (U.S. only): W5W (5 Watts, white incandescent), behind a red lens
→ →♦ ABARTH (along wheel well trailing edge): W5W (5 Watts, white incandescent), behind a red lens; lamp assemblies are common with the ND MX-5
Tail Light Modules {5}:

→ →♦ Rear “Foglamp” (standard for Europe region): W21W, SAE 7440 (21 Watts, white incandescent), behind a red lens.
The Euro rear foglamp is a single lamp, offset from vehicle centerline and reverse light (on the driver’s side, so it’s not confused with brake lights), to meet Euro regulations (provisions for either LHD or RHD exist in the lamp housing); the wiring harness for the rear foglamp exists for all regions (plugged into an empty cavity in the housing for non-Europe), but in order for it to function, a Euro turn signal stalk (has switches for both front and rear foglamps) is required; by drilling hole(s) for bulb socket(s), you can add symmetry to the Euro foglamps (or create an additional pair of brake lights) – BillaVista’s flashing brake lights modification instructions are here.
Center High Mount Stop Light (CHMSL) Module {7}: a row of LEDs, behind a red lens
License plate lights: W5W (5 Watts, white incandescent, behind a clear lens); located on the underside of the decklid; lamp assemblies are common with the ND MX-5

✅ Interactive wiring diagram (right-click it; select Full screen; select Flow; then you’ll be able to see all of the circuit paths that activate either interior light)
✅ Upgrading both interior light bulbs with Super-bright CANbus LED units* is highly recommended for significantly improved lighting
* Note: LED “bulb” substitutions can be made for incandescent bulbs, but they won’t always behave well with the Body Control Module (which interprets the very small circuit current draw as a burned-out bulb, resulting in “hyperflash”), unless: (1) at least one of the bulbs in the respective circuit remains incandescent, or (2) the LED bulbs are CANbus “error-free” units (built-in load resistor), or (3) you splice into the wiring circuit to add your own inline resistor.

Ignition Push Button Switch while pushing clutch pedal (MT) or brake pedal (AT): Each time the keyless ignition START/STOP button is pushed, the engine cycles in START or OFF mode.
Instructions, if key fob battery is dead (or if room fuse is not in place): Starting the car by pushing the START/STOP button by pressing it with the logo end of the fob (rather than using your finger), is how the cars were moved around in “transport mode”, before the room fuse has been installed. There is a RFID chip in the fob that can be detected by the switch, and if the code is correct, will allow the engine to be started. Keep that in mind if your car seems unable to detect the key.
124 SPIDER ~ PAINT
Where to find your paint code: For North American 124 Spiders, MAZDA prints THEIR paint code on the B-pillar VIN placard (just above the striker plate for the driver’s door latch)
Paint: MAZDA‘s “Takumi-nuri”, water-based “Aqua-tech“
Paint thickness (in microns per source, avoid aggressive polishing! as paint is VERY thin due to MAZDA‘s gram strategy):
→ →Aluminum body panels (hood, decklid): 33 μm; (front quarter panels): 46 μm
→ →Steel body panels (Doors, rear quarter panels): 109 μm
click illustration to enlarge; Note the absence of primer. Both paint layers (base and clear topcoat) are applied in succession before being dried (the inner body parts by hand and the outer panels using robots), the entire process taking about 17 minutes per vehicle.

Ameridan I thought you might want this info.
After buying H&R 30/30 lowering springs for 2018 Abarth they actually lowered the car 30 mm at rear and 45mm front with a bone shaking harshness on larger bumps and woeful oversteer and overall balance (do not believe the glowing reports) as an ex formula 3 technician, I decided to check it out and the springs are manufactured to lower 30/30 but not taking into account the front has a ratio of 10 mm at the spring to 15 mm at the wheel hence the 45 mm drop at the front .and the rear has a 1 to 1 ratio as the spring is attached to the hub.
I have refitted the original springs after machining a new groove in the shocker body 15mm lower at rear and 10mm lower at front giving equal lowering of 15mm and maintaining balance and ride quality with lower roll centre .
Also somewhere in my research on the net there was some info about the spring height /wheel travel claiming 0.75 front and 0.66 rear also misinformation. I have measured this myself and my info is correct / feel free to edit this to a more readable diatribe.

I am planning to take my car to a track later this month. But the track owner wants documentation of the Spider’s rollover protection. They allow the current Miata on the track with its factory rollover protection. And they say they will allow my car if I can document it. They told me to check the manufacturer’s specs. But so far I can’t find this info anywhere. I can’t find the info for the Miata either so I can compare. Any idea where I can get this?
LikeLike
Good question! I looked in my Specs files and found nothing. Since “Rollover Protection System” is listed as a standard item for every 124 on some dealer’s sites, and since it consists of EXACTLY the same components as those in the MX-5 (perhaps that is enough for some track owners?), I expected “Rollover Protection System” to appear on my official build sheet, but it isn’t listed there either unfortunately. If it is listed on your build sheet, perhaps that can be used for documentation purposes.
Add your VIN to the end of this link to create a detailed pdf file of your 124 Spider build.
For the heck of it, I added:
Convertible Rollover Protection: same fixed hoops as MX-5to the SPIDER ACCOMMODATIONS section of my Specs page, but I doubt that will carry much weight with track owners 😉
At many SCCA events, apparently the factory hoops are acceptable, but only if your vehicle is otherwise unmodified.

I already had the build sheet. But it doesn’t list any kind of rollover protection. In all my searching I still haven’t really found what I’m looking for. But I did find this link to the safety and security section of the Press Kit for the Spider. I thought you might be interested in it.

If your beach chairs are unusual, you could take one of your chairs to your local dealership and see if you can jam them in. lol Joking aside, you can purchase an aftermarket chromed exterior luggage rack that mounts on the trunk lid… kind of a 50’s/60’s retro kind of look, but with that you could strap pretty much anything on (so long as it didn’t weigh so much that it caved the trunk lid in).

I’m going to stick my neck out and cancel my statement “Abarth wheels have/require individual 433 Mhz TPMS sensors”. I can’t recall all of my sources at the time, but as an example, based on Hound’s comment that insisted on 433 Mhz, if you analyze what actually ended up working for him – the Schrader 33500 TPMS sensor, it actually is capable of using either 433 Mhz or 315 Mhz, and he may not realize that Discount Tire probably changed the frequency from 433 to 315 to get those sensors working.
All indications are that the necessary frequency is in-fact 315 Mhz for our 124 Spiders (the 500s use the 433 Mhz however, which probably adds to the confusion), similar to the MX-5 ND.

Sean Marshall & Ferny Vera have helped to reveal Fiat’s revised recommendation regarding the coolant for the 124 Spider, and I’ve revised the Specs Coolant section to reflect that. Essentially, Fiat got Mopar to stock a FL22 coolant that matches the green coolant that Mazda installs in our cars, and now recommends installing that, instead of the purple coolant, at least until a full flush & replace is performed.

Took my 14,000 mile 2017 to the dealer an extra oil/filter/fluid check 3 weeks ahead of my upcoming 7500 mile road trip. I got it back with new oil and filter plus a “multi-point inspection” sheet showing everything to be perfect. But actually, the coolant level is way below “L” when cold and barely reaches “L” when hot. Next appointments available – after I have to leave. Based on the info here and the fact that no coolant has been added in the past, I’m thinking I need a visit to the Mazda dealer for some green FL-22. But – the Fiat owners book (not always the best source) says when adding (not replacing) the correct Mopar coolant to the car, use a “minimum 50% mix”. With water or what? Does that also apply to the green FL-22 from Mazda ?
LikeLike
John, I bet if you return to the service bay of your dealer, they would add some FL22 for you (if they stock it, as it’s only used in the 124 Spider, which might explain why they skipped). It comes in either premix or concentrate. Distilled water (to insure proper pH) only gets added if coolant concentrate is used! The usual % of added water would be 45%, but in the really cold states, 40% is ideal.
If you visit a Mazda dealer, ask how much for a jug. It may be reasonable, unlike the Mopar product.

A gallon of premix at the Mazda store was $25 including our local 10% tax. They’re closer to my house than Fiat and what’s already in the car is Mazda green so – seemed like the way to go.

Hi Cal. This is the most recent instance. Patricio also installed Alfa Romeo 4c coils (along with Brisk plugs) and found that the tubes were disintegrating from the arcing. By the way, what’s easier: applying the grease to the outside of the plug OR the inside of the tube? I’m assuming the latter. Good to hear yours is running great, but I’ve read that the tubes will have a short life, if there is arcing, which the grease inhibits.

So, I’ve recently come across a Mopar document that has altered a few of the fluid callouts for the 124 Spider, and in some cases disagreeing with workshop manuals and the labels adhered to the vehicle. I think the callouts are vague intentionally, to encourage vehicle owners to have their vehicles serviced at the dealerships.
♦ For instance, they changed the Air Conditioning refrigerant to HFO-123yf, which I think is a typo, because i think they really mean HFO-1234yf, and it is claimed to be a compatible alternative (that meets EU standards) that is a little bit more environmentally friendly than HFC-134a. I’m going to add as a note to my callout on this one.
♦ Next is Automatic Transmission Fluid. The callout has been JWS3309, but now seems to be JWS3324? If you look up the part #, JWS3309 is still specifically specified however, so this may be another error.
♦ The callout for manual transmission fluid is still vague, but I’m leaving the GL4 requirement in my Specs, so that nobody installs a GL-5, or a GL-4/GL-5 combo fluid unknowingly, as that is not a recommended alternative.
♦ The recommended differential gear oil should be 75W-90 SG1, rather than 75W-90 GL-5 that my previous research had revealed. I have a feeling that these two callouts are very similar, and I am leaving my GL5 API rating in place. SG has no published “spec” behind it to identify non-Mazda/non-Fiat products against. And my additive requirement spec for those with LSD, is still spot on.
♦ Mopar finally corrected the callout on the engine coolant to match my Spec, which called for a FL-22 equivalent, as I was already on top of that one.

I just went to both a Mazda and a Fiat place in Canada asking about the differential oil.
Mopar part number is 68333589AA whether it’s the open diff or the LSD for $89 per qt.
Mazda number is 0000-77-SG1-QT for the MX-5 2016+, also known as “Mazda Long Life Hypoid Gear Oil SG1” for $45 per qt.
Neither had any additive to be added to it. I wonder why? Maybe the SG1 stuff is just about a GL-5 with the LSD additive?

The Mazda equivalent always seems to be much cheaper. However, if you have a LSD, just because the additive wasn’t in stock, doesn’t mean it shouldn’t be added. Because of the low volume, the Parts Departments are stocking very few items for 124 Spiders. If you check the Owner’s Manual, you’ll see the required additive. There is also a good possibility that the dealer hasn’t had to work on any LSDs yet, but the additive is definitely required, and both Service and Parts Departments should absolutely be familiar with that (see document below).
I provided a Mopar part # and link to help you locate the required additive, or as one alternative, you might consider the AMSOIL equivalent that has the additive already included in a package that is supposed to make it very convenient to fill the differential.

Yeah my bad, I didn’t mean they didn’t have it in stock.
I don’t have a picture, but I looked at similar papers on both dealers’ computers. Neither dealers mentioned the additive being needed.

Added to Battery Specs: The ⊕ positive terminal should always be disconnected from the battery, prior to working on any electrical/electronic components:
• Tap the brake pedal afterwards, to completely discharge residual power
• Afterwards, upon re-connection, all modules learn current configurations
• The sensor module attached to the ⊖ negative terminal makes it somewhat fragile
And added to Engine Specs: Re-calibrate Throttle Pedal (required after any ECU alterations): Ign ON (not ACC; more), press accel pedal to the floor 5X (within 10 seconds), Ign OFF (for another 10 seconds)

Sorry, but I don’t comprehend which coils you are recommending as upgrades to the Mopar coils??
Bosch, Eldor or both? Has anyone verified that they are indeed better?
And what are the Alt #s (Mopar, Fiat,)??
I notice that Eurocompulsion doesn’t reveal any Bosch part #s for the Alfa coils they sell, and they state “A great replacement for the inferior factory BERU coil-packs”. Are the Mopar coils BERU? I thought I read somewhere that Mopar coils haven’t been BERU since the 124 has been in production, and that they are actually Bosch as well?
I’ll gladly add the recommendation back to the Specs section (it was there at one time) once the confusion is cleared up as to whether the Alfa coils are actually better, and which ones specifically.

My bad, I didn’t read the entire comment thread.
Those are Alfa 4C coils mentioned on a Fiat 500 forum. Alfa switched from Bosch to Eldor units in 2015, which seem to be better.
I am a little confused, trying to find more info, and don’t know if we need the upgrade on the 124. Another person mentioned we already have the upgraded coils, and taking the cover off on mine shows some Eldor units but with different part numbers than the Alfa 4C ones.

Hi ameridan,
Great site! Thanks so much for doing it.
I was wondering if you might know if that lighter blue (Azzurro Italia / PBP (KBP 599)) only shows up on the limited edition 2017s, also known as Prima Edizione Lusso, of which apparently only 124 were sold in the US ?
Thanks much in advance, for any help.

I like the second one here because of the larger paint examples, and if you hover over them, it shows a pop up with alternate names for the paint (should it be one that gets called by several different names for that same paint code).
On my build sheet, my mirror caps and window trim are listed at Gun Metallic, and I’ve yet to find anything matching that name.

Paul, are you referring to the side marker lights on the fenders, just behind the front wheel wells? If yes, and you may have already done this, do a quick check of your fuses to make sure none are burned out. The side markers behind the front wheel wells are enclosed units and the bulbs are not replaceable in them. You have to purchase and replace the entire component, including the angular plastic housing that fits on the fender. If you do have to replace them, I recommend sourcing a non-OEM replacement from Moss Motors that does allow you to replace just the bulbs. It’s a one time up front cost that’s on par with the cost of the OEM units, but any subsequent bulb burn outs become dramatically less expensive.

When Paul stated “turn side lights on and only tail and rear number plate illuminate”, I assumed he meant the lights behind the rear wheels, and I find it hard to believe both those bulbs have failed already, so I didn’t have anything helpful to offer.
The front lights Cal mentions will only illuminate in conjunction with the turn signals, so Paul if those are the lights in question, there is probably nothing wrong, as shown in this photo:

Paul Carruthers – then I think the next logical step would be to replace the two bulbs, or at least replace one to see if that’s the fix. If you look around page 136 of your owner manual (in the section called Replacing a Bulb in the Abarth version of the owner manual), it shows you how to gain access to the bulb in question. It will require the removal of five plastic pins that hold the front section of your front wheel liner in place, and, turning the wheel to give you more access to the space.
Here on Dan’s most excellent reference site, under the specs, exterior lights section, you’ll find a link that points to a thread on the 124spider.org site. Scroll down about two thirds of the way in that thread, and you’ll see detailed instructions on how to access and change these bulbs. It’s more detailed than what’s in the owner’s manual, and might be easier to understand if you’ve never done this before on the Spider.
In all honesty, anything above the fog lights is hard for me to get to without actually removing the tire from the car. My hands and arms are too big to fit in the gap when you merely turn the wheel all the way in one direction. I don’t know your “do it yourself” skill levels, but if you don’t have the tools to lift your vehicle to safely remove the tire, it might just be best to take it to a shop to get the bulbs replaced.
I’m hoping this is just a matter of coincidence that both bulbs burnt out at the same time, because if it’s just a bulb replacement, it’s relatively easy, fast, and one of the least expensive repairs to can complete. Best wishes for success…
One final small tip…. a very small flat bladed screwdriver is an excellent tool to pop out those plastic rivets that hold the fender liner in place. They each consist of two pieces, an outer housing, and an inner pin that you need to pop partially out to loosen the rivet assembly so it can be extracted from the vehicle.

Had to use my fog lights yesterday and was astonished about their non-performance. Ordered a set of Osram Night Breaker Silvers and had the OEM replaced this morning at the dealer. Already had an appointment there for mounting winter tyres so they changed the lamps for free *thumbs up*
Little information tidbit:
OEM fog lights in mine were Philips H11 LL (product code 12362 LL). A quick google search indicates that this is a long life (hence LL) bulb, probably this https://www.philips.co.uk/c-p/12362LLECOC1/longlife-ecovision-car-headlight-bulb.
Wondering if LL also stands for ‘less light’ 😉
Subjectively the Osrams are brighter. Have to wait until the next time we’re having fog for a more profound verdict.
