Thread: Just bought a 2004 Grand Prix Gtp Comp G but many problems..

no prob, ive been to queens, the best bet for a shop for you guys have is like strauss auto or some other sh!t chain shop lol and would not go there.


plug gap you stick the gap tool inside the spark plug end's and twist it till you get it where you want it to be.

tb is throttle body, where the air filter hose hooks up to the engine.

yes air in the engine, the s/c oil needs changing like every 30,000 miles, or so heres a vid how to do it, YouTube - ‪HOW TO CHANGE THE SUPERCHARGER OIL ON A GM 3800 SERIES II V6‬‏ get new oil from a GM dealer only.

Some guy said the car was overheating because of my water pump, but I did not trust him. Could this be true?

As for fuel mileage, since the air filter and plugs and wires were done. I want you to try and clean the MAF with maf cleaner and I would prolly change the front o2 sensor.

Is there a way to know when you need to change the lower intake gasket?

you may be due for a lower intake gasket, the shops in queens are going to rape you on that one.

Ok awesome, thanks so much.

There is a plug on the front of what we call the "snout" which is the part with the pulley on the end, that bolts into two other peices that make up the blower.

The fluid can be sucked out with a syringe and some tubing.

Then go to the dealer and ask for two bottles of supercharger fluid.

fill till its at the bottom of the threads of the plug. (make sure the car is level)

Gotta take the engine cover to see that though.

I'd suggest throwing out the engine cover. Just makes things hotter and decreases the life of everything.

If you're in a bind, Mobil 1 5W-30 is a GM approved temporary solution for southern states all year 'round or summer only in northern states.

water pumps work till they leak like mad,(and then they still work) or seize up, so i would say no.

best way to check the lim is to have the cooling system pressure tested.

im pretty sure you can buy that tool, a shop shouldn't charge that much to do it tho.

you just live in a bad town, every shop there is a back yard butcher, or a flat tire fix shop that sells rims lol

that sounds like a loose wire, or maybe the blower motor resistor, witch is under the dash behind the glove box, along with the blower its self, theres a write up here in the how to section on that, i haven't had to deal with it myself yet. search away for that one.

your car aint from queens NY lol, the city life is so hard on car over here, bad roads bad shops and people who drive cars till they stop working and they get left on the side of the cross Bronx expressway for the insurance money,(cars used to get stripped over night if left on that highway) if they have insurance that is.
