get a ratchet and a socket that fits the nut on the pulley. turn either left or Right, not sure been a while. one of the two will move the tensioner enough to get the belt off...
in the front where the belt is at unders the power steering pump .

you can't disable it. the only way not to spin the supercharger is take the belt off the supercharger. there are 2 belts on these engines. the one that drives the supercharger does not run anything else. to remove you need to get a 15 mm soclet and rachet and place it on the bolt of the tensioner. take the tension off and remove the belt. only advantage would be you wouldn't be making boost so not as much fuel is added. disadvantage would be that a Honda civic would beat you.
use ratchet on square hole on tensioner to pull it back and loosen belt
How do you change the supercharger belt tensioner in 1997 Pontiac Grand Prix GTP?
the timing belt tensioner is located on the lower side of the rear head just below the camshaft drives
The Pontiac Grand Prix has a Timing Chain with a spring loaded tensioner. The tensioner is know to wear, crack and then break. The timing chain and tensioner should be replaced at 100,000 miles. This is a pretty big job that can be done with the motor in the car. $$$ Ray
Usually it takes a 3/8 or a 1/2 inch rachet on the spring loaded tensioner. simply put the rachet in the square hole and loosen the tension to get the belt off.
The idler pulley is the tensioner for the serpentine belt. To loosen it, do the following... - Notice the bolt in the centre of the idler pulley. Find the appropriate socket. - Using your rachet (set to loosen) put the socket on the bolt so that the rachet handle is pointing towards the windsheild. - Push down on the rachet handle. The tensioner will give slack to the belt. (careful because it is under spring tension) - While holding the tensioner down slip the belt off. Gently allow the tensioner to spring back slowly until it stops.
look how it is routed before removal. There is a tensioner that holds the belt tight. Use a wrench to hold the tension off the belt while you pull the out from under the tensioner. install new belt the same as old.
there is a bolt in the center that is a 15mm that you will have two take out two change the belt tensioner and there is a pin that has two line back up on the block when you change it so that it seats right for the right tension .
Pontiac Grand Prix does not have a timing belt. It has a timing chain and it is replaced when it breaks.
Use a 3/8" drive ratchet and insert it into the square 3/8" slot on the tension wheel and turn appropriately.
that alt belt is a serpentine belt so you should take a picture of how the belt looks right now and then put a wrench on the tensioner pulley and relax the tensioner so that you can pull the belt off of one pulley then you can let the tensioner back so you have both hands free to pull out the old belt reverse steps to replace
it has a timing chain
