I have a serpentine belt that is making noise. It does not appear to be warn. Is their a belt tightening procedure or alignment procedure? Any help appreciated. Thanks

It is probably stretched out. There is an automatic tensioners that regulates the force applied to the belt. Just put a new one on if the belt is original.

wow... didn't see that comming. It seems a little premature for those to fail so soon. At least you got it fixed on the house

Idler pulley and tension pulley replaced today under warranty. Dealer said bearings were noisy causing the whine. Good for another 33K miles.
