I’ve owned this car for over 10yrs. It has very low miles and has been very well maintained. The motor internals are stock as well as the turbo; it even still has the R12 freon in the A\C which works. With in the last year I have had the valve stem seals replaced, valve cover gaskets and oil pan...

For as long as I have owned my 87 GN, the rad fan has been loose at the bottom. I was wondering is that normal? Doesn't seem to be but I've seen stranger. To be clear, if you reach in and grab the fan housing, it's attached at the top but not at the bottom. I looked down to see if maybe...

I've decoded everything on the cowl tag except for the upper right corner. There is a "P" then space and then six numbers. I'm guessing maybe the p stands for pontiac assembly plant, don't know. Thanks for any help.

I found the production numbers for GNs total in 87 but nothing about how many were t-top cars. Thanks very much.

I have a question about the plastic seatbelt guide attached to the headrest. How does the seatbelt work with this piece? Is the seatbelt suppose to run behind it or what? "When" I wear my seatbelt I have to put it on and then reach behind me to run it behind the guide or it cuts into my neck...

My GN still has r12 in it but the compressor has started cycling more so its time for a recharge. I'm wanting to update to r134 for but I'm wondering what needs to be done. I've read from one extreme to another, replacing everything to going to advance and getting a "kit". I'd like to hear from...

I'm wanting to remove the black trunk lid trim that runs along the edge so I can paint it. I've removed the three screws but it will not move. Recommendations? Tks

Can this be fixed? It looks like I'd have to remove the door panel and take the mirror off the car to access the bolt to tighten it. That sound right ?

Need the correct measurement specs for proper hood emblem positioning on an 87 GN. Thanks

I have a 87 GN with 30k on it. I have only a few mild mods and I am not trying to turn this car into some kind of monster. Motor internals are stock, trans is stock along with converter. I've installed msd 50lb injectors, CAI, Hooker exhaust, afpr, 160 thermostat, TurboTweak chip, walbro fuel...

Is that a factory option or dealer installed option? Thanks

I want to repaint not only the tail light trim pieces but also the wheel opening mouldings, the trim on the trunk edge, key cylinders, ETC..... What is the correct color? Flat black, semi gloss??? Thanks..

The brake light stays on all the time. I have 12v to the motor and the ground is good. With the key on and the switch on top unplugged, I am grounding the white wire and the motor does not run, I only hear and feel a click from the motor. I also tested the continuity of the switch and it is ok...

Rpms run up to around 3300 before shifting into 2nd. I have tried adjusting the TV cable. The cable does not adjust correctly on its own. I have manually adjusted to several different positions and it does not make a difference. Someone mentioned to me that the spring may have come off in the...

As the title says, I have checked with the GM dealerships.... discontinued. Can some one tell me if it is available aftermarket? Thanks

Hello, I tried adjusting the TV cable and thought it worked. I took it out for a short drive and it runs up to about 3300 hundred rpms and it will shift from 1st to 2nd. Tried to adjust again and with the cable pulled all the way back, I noticed the cable does not click at all with WOT. I...

I want something clean that does not take up a bunch of room. I know some companys make specialized enclosures but have not found any for the GN. Looking for something that sits under the rear 4x10s. No preference on size or amount of speakers. One 10 inch sub will probably be all I need. Thanks.

I believe in coincidence but I am not so sure I did not cause this. This problem started after I over filled the master cylinder. I topped it off with out pumping the brake pedal and when I did it blew out around the reservoir lid. Is it possible to have damaged the master cylinder internally...

:confused:

Brakes went out and checking somethings. Is there a procedure to replace the switch or just unscrew it? Thanks
