my serp. belt is riding the inside edge of the crank pully. its done this twice. everything is tight and aligned. the belt is two years old.
since my ac doesnt work, i want to lose it. i like the idea of converting to v belt. other than brackets, clockwise water pump, and pullys, it seems easy. suggestions?

 

any idea why it's doing it? sounds like your balancer may not be back far enough...

 

Thats what I was thinking. Either that or your tensioner is shot and allowing the belt to "walk" on top of your balancer pully. Maybe try to put a level on your top part of your belt and lower part and see if maybe your balancer is out a bit or if your bel is not straight up and down.

 

make sure it is all really aligned properly...
