on my 1995 4.0 L OHV it is located below the alternator
Your Explorer has a serpentine belt tensioner which keeps the proper tension on the serpentine belt unless the tensioner has failed.
There should be an engine belt diagram near the latch that keeps your hood closed.
near the belt
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?
belt tensioner fell off this morning.I need to know how to install new one.
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.
