1998 Chevrolet Monte Carlo Q&A

1998 Chevrolet Monte Carlo Question: Why does a serpetine belt keep coming off.

The origanial belt was replaced a few years ago, then all of a sudden the belt came off. Replaced it with a new belt and it will not stay on. Could it be the auto tensioner is worn out? -
Answer 1
My suspicion is the auto belt tensioner is worn causing the belt to misalign with the other pullies. -
