[UPDATED 11/27/2016, 12/3/2016]
My next project is going to be an installation of the Cobalt Hood Lift Kit (part # 910-720) that was developed for the Mazda MX-5 (ND) and has been verified to work on the Fiat 124 Spider as well. People seeing my vehicle at car shows keep asking me to pop the hood so they can peruse Fiat’s longitudinal placement of the Abarth engine, so I figure – why not make the hood opening process easier, like the hoods in most classic cars?
I’m waiting for one of the vendors to have a free-shipping promotion, so that I can put in my order.
Even better than free shipping, MossMiata.com had part # 910-720 Hood Lift Kit (make sure you select the correct model) on sale for $79.99 ($20 off) and so with S/H ($14.49), the total came to $94.48. I put in my order.
I installed the kit today (12/3/2016) and although I oriented the quarter panel brackets incorrectly, the install still went very smoothly after swapping them. So here are my installation tips:
Make sure the brackets on the quarter panels are oriented such that the ball studs are inline with the forward holes. I later realized that there are two applicable photos in the instructions – one with Step 3 and another with Step 4. In my opinion, the Step 3 photo (which I had concentrated on) could have been eliminated and substituted with a less confusing version of the Step 4 photo. The Step 4 photo is technically correct, but the orientation lead me to install the brackets incorrectly (ball stud inline with the rear hole) and I had to remove them both, swap and reinstall. I feel that the photo should have been oriented as it would look when you’re standing there facing the opened hood (not standing in the passenger’s seat), with the “Forward” arrow (which had escaped my notice) aiming down, as the photographer did for the Step 2 photo. When the gas struts appeared to be too long, I realized my mistake.
I found it much more convenient during installation, to hold the hood up higher than the prop rod holds it by using an adjustable pole for a ceiling paint roller. It just makes getting to the hood bracket bolts so much easier, and as long as the instructions are followed, the hood won’t shift as you’re working on the hood brackets because 3 of the 4 bolts will always be in place. The instructions said to “support the hood with one hand and remove the top bolt” and later after reinserting it, “continue to support the bottom corner of the hood and remove the bottom hinge bolt”, but I didn’t find supporting the hood necessary – perhaps because the hood was in a more convenient position and/or perhaps because I did the install in my garage, not in a windy driveway.
I just used scissors to cut ¾” off of each end of the firewall seal, rather than cutting just the vertical portion off as the picture below seems to illustrate.
I also couldn’t believe how easy it was to remove the prop rod afterwards – you simply push in towards the center, 3 of the 4 tabs on the round plastic bracket that holds the rod at it’s swivel point. The prop rod is useless after the kit is installed anyways.
In my opinion – – –
INSTRUCTIONS COULD BE MORE INTUITIVE, BUT EXCELLENT PRODUCT!!
Cobalt’s Progressive Struts are said to start assisting the hood opening about half way up and gently lift it to the fully open position (even further than the factory prop rod). They claim that other kits use inexpensive linear struts that are either too strong or to weak that cause the hood to raise so fast it comes to a shuddering stop at the top stressing all components or requires you to lift the hood all the way open yourself. The stress from those can also exert a bowing force at the mounting point of the hood. Makes sense to me.
Preview the installation instructions of this kit that uses bolts and the welded threaded nuts already in place on the vehicle, and I think you’ll agree that this
should be is an easy project. The struts actually lift the hood much higher than the prop rod (and more securely), giving you greater access to everything in the engine compartment.
Interesting side story…
* Because of stringent pedestrian crash standards in the European Union, MX-5s and Fiat 124 Spiders produced for that market having such low hoods are required to incorporate “Impact Absorption Bonnets” (a.k.a. Deployable Hood Systems; Australians also get them) to mitigate the impact to a pedestrian’s head (into the windshield) in a frontal impact if the vehicle is travelling above 20 km/h, by popping up the rear end of the hood with two gas propelled actuators. These actuators fire against a small plate attached to the hood on each side which instantly lifts the rear of the bonnet by 120mm, creating a crumple zone above the engine to absorb some of the impact energy with the unfortunate pedestrian. Also note in this Euro NCAP YouTube video, that it shows the active bonnet in action. Once activated the system will display a flashing red dashboard warning light (Check Bonnet) and parts will need to be replaced by Mazda as the actuators cannot be re-used.
I suspect that the holes and weld-nuts in the quarter panels that these hood lift kits use, were originally designed for hood lifts, but were re-purposed for the active-hood actuators in European vehicles.
In non-European vehicles, blank plates are bolted over these same holes and the hoods are held in the up position for all global markets, with a prop rod instead. These hood kits replace those blank plates on the quarter panels with brackets, and two additional brackets are mounted on top of the hood’s hinge brackets, so by using all of the existing bolts and welded threaded nuts, an easy OEM-looking installation is accomplished.
