Go to www.zzperformance.com and you will be able to rent a pulley puller do not use a regular pulley puller they. It is about 30 bucks to rent. It will take about an hour to do

Yes
Could be the bearings/pulley. until you fix the issue you should remove the charger belt, so it doesn't get worse (blow the supercharger).
put a socket on the tensioner pulley and pull on it until there is slack then just slip it off.
do not remove your supercharger belt, the engine is set up to work with supercharger. my belt broke on mine and i was told to replace it before i drive it to much
How do you change the supercharger belt tensioner in 1997 Pontiac Grand Prix GTP?
no
means the car has a supercharger
Yes you can, but you will need some things Here is a list GTP Supercharger w/ bolts and pulley GTP Throttle body GTP Fuel Injectors GTP Lower Intake Manifold GTP Cylinder Heads w/ valve covers Passenger motor mount GTP Harmonic Ballencer GTP supercharger belt tensioner and idler pulleys GTP MAP sensor GTP Vacuum lines Head Gasket set Head Bolt Set Lower Intake Manifold Gasket GTP Valve Cover Gaskets Supercharger gasket and coolent O Rings Throttle Body Gasket MAP/BBV harness adaptors PCM Tune In my opinion, you would be WAY better off just buying an L67 engine. I have seen those on craigslist from $200 to $500. Ya it will be a little bit more frustrating, but so will putting and replacing parts from a gtp onto your gt. But good luck though :)
You would need to remove the pulley and place a smaller pulley on to make the supercharger turn faster and pump more air. This can be done to a point but if you go too small without doing alot of other modifications to the intake and exhaust you will burn up your motor in no time. Check out the following website. http://www.gtpworld.com/index.html Read and learn from others mistakes. Hope this helps.
You will need to remove the front engine cover, on your 1997 Pontiac Bonneville, in order to change the supercharger belt. Loosen the tensioner pulley to remove the belt.
