Thanks HotZ28 for the tip.....

In July 09 you recommended Goodyear Gatorback belt for smith1000 when he had a "chirping" problem with his serpentine belt. I tried it for my same type problem and it worked. This problem started after I replaced a blown a/c compressor with a Dorman Idler pulley. I think there must have been a slight mis-allignment of the pulleys that helped cause the "chirp". Thanks for the tip.

Thanks for the feedback, and good to here you had positive results. Metal pulleys tend to chirp more than plastic, especially if there is a slight misalignment. If you have any metal idler pulleys, I would suggest replacing them with plastic. This is the reason plastic was installed at the factory.

Actually, HotZ28, I had already replaced the spring-loaded idler pulley in an effort to solve the chirp problem. When I had the belt off I checked all the other pulleys, too. I never thot to replace the nearly new belt until I read your old post.
Of course, Gatorback belt solved it.
