Belt issues

My wife’s 03 is having a problem with its serpentine belt jumping off of the car. belt is new… I wounder if its the belt beeing crappy… Any suggestions would be great.

problem sounds like a bad tenstioner. or wrong size belt would double check the length they sold u.

I would take the belt off and check the belt 1st. My belt was making noise (not the same problem I realize) and when I took it off to change to Powders UDP, the belt had chunks missing out of the grooves.

If its not the belt then go for that tensioner.

Thats what i figured… time to swap tensioners… yah…
