Default Hood/Bonnet opening mechanism questions

I have a couple of sets that allow the hood to be opened wider for engine service from earlier E36 cars.

It looks like I can I add them to my '97M 2/3/5 with no change to the lift struts because the extension is in the added mechanism.

Do I need to factor in any negatives to doing so?

Thanks!

I wasn’t aware this was available on any Coupe. All sedan have this feature.

The “service mode,” which you get to by removing a small screw on both hood hinges? My 99 coupe’s hinges have that feature.

No, and that isn’t for over opening the hood, it is for cowl/windshield work. Sedan can open their hoods to a 90deg angle.

What's the difference? When I undo those torx screws on my coupe, it lets the hood open to 90 degrees.

I've never worked on a sedan by the way, just coupes.

I’m unaware of that being the case on Coupes. It will stay on it own too? Sedan have a flip latch on one side for quick service mode and doesn’t compromise safety. Coupe are anything but quick, and in any normal position with those torx out the hood falls.

No, it won't stay up on its own, and it's not quick since you have to undo the torx bolts.

I think we're all talking about the same thing you mentioned earlier for cowl/windshield work. It also allows greater hood opening, but apparently isn't as easy or safe as the sedan service mode.

I’m not seeing how the coupe hinges, torx removed, allows for greater opening. I distinctly remember it doing nothing as you hold the hood up to reinstall the service mode bolts.

The hood moves forward, thus it can open wider without having to remove the hood shocks.

It works on cabrio’s as well.

The system is not as easy as sedans/touring. With the grubscrews removed, you can move the hood forward and access the scuttle panel’s corners. But when you lift the hood, it opens much lower, untill you press it backwards (to fold back in the mini hinge).

However with the shocks removed, it allows the hood to be folded back onto the windshield.
