Squeaking from Serpentine belt, Pulleys?

I have a very annoying and consistant squeaking noise coming from my serpentine belt/pulley area. I had heard it might be an old idle pulley. when i look at it while running the tensioner is moving a bit. But i had that replaced a year ago. Any information will help. Thanks!

How old is the belt and what brand is it....... The tensioner can wear out and will squeek if the spring is weak. Ensure the noise is not coming from the vacuum pump pulley.

If you have replaced the belt recently what length did you use???

Go to my pics under my name there should be a picture of the bolts holding the tensioner and other appliances to the engine..... there are several different bolts.

The belt is in good condition. and for some reason the squealing is most prevalent when it is cold outside.

Is it pretty easy to replace the idler pulley? my tensioner assembly is basically brand new.

yeah it's pretty east, the bolt is the same size as the one that holds the tensioner on. if you had to replace the tensioner you would have had tp pull off teh idler pully. I know the tensioner pully(not the tensioner bolt ) loosens to the right and not the left...on the other hand the idler pully loosens to the left, like a normal bolt.

If you pull the bolt off and spin the idler pully and check it for 'walk' or movement in all directions, you should be able to tell if you need to replace it. check the other pullys on the alternator, powersteering, water pump etc.

it's hard to describe, but you will be able to tell by feeling it. there should be very little to no movement.

If you spin it and it has a dry sound it is fubar..... As for sideways movement (wiggle) there should be none......
