Did you replace the tensioner assembly? Perhaps the spring on the tensioner is worn out. Also make sure that all the pulleys are lined up and the belt is routed correctly. If someone else replaced the crankshaft pulley with one for a supercharged engine there'll be 2 pulleys on it. I believe that the inner pulley is for the accessories and the outer one is for the supercharger only. So use the inner pulley if that's the case. HTH. -Jim

Was this a new belt that you just installed ? That is one thing about a serpentine belt you think you can remember how it went on but you don't so many combinations you may think you got it right but it is not. Most part stores like auto zone will give you a print out of how the belt is routed on the engine for free.

Are the edges of one pulley missing ?
