The smooth rounded tensioner pulley has a 1/2 inch drive recessed
ratchet drive fitting in the outer side of it. Reach down and feel it
with your fingers and insert the ratchet drive into it. Look around the
underside of the hood and engine bay for a small diagram showing the
belt, pulleys and tensioner.
This pulley is either a slider or a spring loaded pulley. If it is a slider, there will be one or two bolts with "slide" areas that the bolt can move through, and possibly a third bolt that controls the tension. If it is a spring loader, there will be a pulley that looks like it is on a lever. There will be a "bolt" type head, a hole for a ratchet, or a square area on the end of the lever to twist it away from the belt. If it is one of these, the belt tensioner will move relatively easy.

I have a 1995 xj6....same problem. I replaced the belts, water pump, and the alternator. Still does it. As I play with the tension on the belt (belt that drives water pump, alternator) it goes away and comes back. If I remove the belt, the metal to metal screech stops. I then, with just the belt, turned the main pulley on the front of the engine, and there was the sound! The main pulley has 2 belts that run on it. Also, 2 pulley tracks. They SHOULD move simultaneously and be super meshed. But the rear one moves on its own under tension until it warms up and I guess, the bushing maybe expands. Now.....how do I fix it??????

If garage replaced alternator, return vehicle for warranty work.
If you replaced alternator, what was wrong woth old unit??
Provided regulator is internal with alterantor, fault is with alternator.
If an external regulator is used then its faulty.
What voltage reading are you getting at idle / 1500rpm??

never spray wd40 on your belts,if it gets on the pulley the alternator or power steering will slip and not work,
listen with an extension bar and pin point noise,if its a bearing in something or maybe just replace the belt for cracks.
