I replaced my serpentine belt a few months ago and I just replaced it again last week- the belt had a strip about 1/4" wide and 18" long gone off of it.

I got it from Advanced and it had a 1 year replacement warranty so the second was no charge <img src="/forums/images/graemlins/kewl.gif" alt="" />. The second belt was much beefier and I think a little smaller because it was much harder to get on.

OK, here is the question- I notice that the belt looks fine on all pulleys except the tensioner- it rides right against the front lip of the tensioner that keeps the belt from falling off, is there some kind of adjustment that I can make to resolve this or is it normal?
