Remove supercharger on pontiac GTP 1999

I need to change the lower intake manifold gasket of my pontiac grand prix GTP 1999, do I have to change the Supercharger gasket and what difference makes to install a thinner and a thicker gasket on the SC.
Is there any place where I can see the procedure.
Thanks

Technically you are supposed to (change the s/c gasket) but if your careful and don't tear it, you don't really need to.

Be sure to inspect the yellow coolant o-rings.

The gasket thickness isn't going to matter at all on the supercharger gasket.

Perfect oportunity to install that Intercooler you always wanted ;)

SOURCE: I have a 1997 Grand Prix GTP and the Supercharger

sometimes they just go out....lack of lubrication can cause problems but more then likely it is just going out. Try taking the air cleaner off and reaching in where the fins are and you will see a nut on the end, grab the nut and see if there is any play moving it up and down. If there is any play then the bearing is going out.

SOURCE: 1998 Pontiac Grand Prix GTP Supercharger coupler

The rattle you are/were hearing is typical on the Eaton blowers. After they get some miles on them, the coupler wears out and the holes become ob-longed or out of round which causes the rattle you are hearing.
Usually at idle you can hear it very clearly.
I have changed a few, and they are pretty simple to change. Just take off the supercharger belt, then you may have to remove your alternator bracket, depends on which years, drain the supercharger oil with a spray bottle sprayer (it does stink badly) then just remove the 10 or so bolts that hold the snout to the housing. Remember to keep track of where they go, some are different lengths.
You may have to use a rubber mallet, or your hand to hit the snout around to break the gaskets loose. Pull off the old black hockey puck looking thing (coupler) clean out the snout, attach new coupler, then reassemble and put new supercharger oil back in, and your rattle will be gone, at least for another 100k miles.
Best place to get a coupler is at,

Costs about 30, plus the few bottles of oil for the supercharger.

SOURCE: How supercharger oil is need for the supercharger,

The oil should be changed every 30K miles according to the Pontiac manual.
However, it is best to change it sooner or whenever you don't know when the last change was done.

SOURCE: replace thermostat on 2003 grand prix gtp with

The thermostat housing is located in the upper radiator hose. You will see a metal elbow secured by two bolts into what I remember is the upper intake manifold...don't quote me on that but you will see it regardless of whatever I call it. Anyways, GM decided it was a good idea to put stainless steel bolts in there but that makes it easy to strip the threads in the bolt hole so I think it's best when you put your wrench on the bolt to just tap on the handle till you vibrate it loose, then turn it.
When you pull off the housing you'll lose a little coolant and it will create an air pocket which we'll address. It's a 50/50 chance that the thermostat housing gasket will either stick to the housing or the engine...it may be torn, cracked or flaking in either case clean both contact surfaces before you replace the gasket. I recommend an oil impregnated poly material gasket.
Note the position of the thermostat in the hole and place the new one in as such.
I recommend a 180 degree thermostat...stock is 195 but the GTP runs better with the 180.
Put on gasket and reinstall the hose/housing assembly, alternate from one bolt to the other so the housing mates flat and cannot cause a leak.
Next, fill the coolant overflow bottle to the "HOT" mark. If the bottle is dirty and hard to see just put a light on top of the bottle...GM didn't mark it very well so if it's not squeaky clean you can hardly see a damn thing.
*IMPORTANT** if your car still has Dexcool in it, DUMP IT. It will eventually destroy the motor.
If not...continue on. Start the car. Go back to the thermostat housing and place a rag on top of, and twist the peacock valve on top of it to let the air out until it starts to get coolant on the rag. Done.

Double check the wiring harness to make sure it did not get pinched under the manifold or the top cover. It is common for a single wire to get pinched and shorted and cause this.

did you check the lower intake manifold gaskets? they go bad on the 3800 series 2, since you have the supercharger you won't have an issue with the upper intake because it is not plastic but the gaskets may be bad as well. that engine runs best with irridium plugs.

I have a 2000 pontiac grand prix gtp with supercharger. I have oil in coolant reservoir, I am not getting the white steam from exhaust pipes. car runs fine. not overheating. I checked the oil dipstick and...


The reason for this is because your trans cooler(which is built into the radiator itself) has failed and burst causing trans fluid to contaminate the cooling system.The fix for this is to remove and replace the radiator with a new one and then flush your cooling system to remove all trans fluid.I hope I could help!!! Any other questions please get back to me and rate me accordingly.

Replacing 90 pipe assembly part on 1997 Grand Prix GT


If its the same as my GTP, its just under the Supercharger right in the middle of the intake.
Just pull it out, its only held in with a O-ring. When you replace it, make sure you lube the gasket with grease so its easier to put back in, and less likely to nick the O-ring.
