Look under the alternator , as your standing , facing the front of the engine , to your left follow the belt down . It has a 3/8 square in it so you can use a ratchet to take the tension off the belt for removal. Easy to replace attached by one bolt to the engine and is sold as a unit (arm , sprng assembly and roller) for around $20.00. Just alot of stuff to reach through to get to it.
on my 1995 4.0 L OHV it is located below the alternator
The belt tensioner is located at the bottom of the power steering pump looking at it from the front the tensioner is on the bottom left. you could always loosen the alternator up a little. My 1997 with a 4.0 does not have a tensioner pulley, and I believe the 99s are the same. the alternator is the tensioner. Remove one of the bolts and it will swivel in and you can get the belt off
How do you change the supercharger belt tensioner in 1997 Pontiac Grand Prix GTP?
As viewing the motor from the front of the car, the belt tensioner is located on the left side of the engine. On what is essentially the front of the motor, the belt tensioner is located just below the idler pulley.
You dont! The belt is self adjusting with the belt tensioner. Check the tensioner for failure or damage if your belt is loose good luck
Powe stering belt (aka serpentine belt) is tightened with a belt tensioner. A new tensioner is needed if the belt is loose or a new belt
anywhere on the belt most likely close to the alt.
Remove the serpentine belt. Tensioner is below Alternator. Remove the three mounting bolts on the tensioner baracket assembly. Replace entire unit.
Look in the engine compartment for the "serpentine belt" path & tensioner diagram. Release the belt tension at the tensioner, remove & reverse operation.

The timing chain is on the front of the engine. Your drive belt tensioner pulley is bolted into the timing chain housing.
go to a napa store they have these diagrams in their belt book
