99 Grand Prix GTP pulley for Supercharger...

I had the pulley for the supercharger replaced about a year or so ago. Yesterday I was driving, smelled something burning so pulled over. The SC belt was laying on the engine and the plastic(?) grooves for the pulley had broken off and the ring of grooves(all of them still intact) was laying on my battery. What is the usual warranty on the pulley? I had it replaced by an independent garage.

Has anyone ever heard of this happening? The pulley didn't break, the grooves broke off...

Would replacing a power steering pump in a 2002 Grand Prix GTP Supercharger cause the SuperCharger belt to break.


No.

The supercharger belt is on the main drive, the water pump is on the accessory drive. Provided that they are both properly installed of course.

Yes I have a 1998 pontiac grand prix gtp on the supercharger, there is a pulley on the end of it!. Does this pulley have a bearing in it!


The pulley itself does not have a bearing in it. The shaft however that the pulley is pressed onto does, inside the snout.

2000 Grand Prix GTP supercharger fluctuates when accelerating


There is no wastegate.

Change the spark plugs and pay special attention to the plug on bank 3. Look for physical damage on the electrode...cracked, bent etc.
Use Autolite 605's copper core gapped to .055" and NEVER run less than 92 octane.

I have a 2003 Grand Prix GTP and when I start the car there is a loud metal-on-metal screaming noise coming from the supercharger area. I assume this is bad news for the supercharger but is it safe to...


Have it towed as the blower has probably lost one or more bearings. If metal shavings enter the cylinders, there could be serious damage there as well. Good luck!

How supercharger oil is need for the supercharger, 1997 Grand Prix GTP?


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.

Im looking at purchasing an 02 GTP but my mechanic friends tell me to stay away from them because the superchargers have issues? are they right?


Remanufactured nose drive kits consisting of nose cone, drive pulley, lubricant,
sealant and coupler are available. The nose kits are an excellent alternative to replacing an
entire supercharger when dealing with low mileage bearing noise or leaky seal concerns.

This was from a service bulletin in June 2003.
