Aluminum pulley squeal - The 1947 - Present Chevrolet & GMC Truck Message Board Network

KEH · 09-14-2005, 10:44 PM

I have replaced the water pump pulley now a couple of times because of belt squealing when running the a/c. I have replaced the belts, which temporarily solves the problem, but the squealing returns after a few days.

I have tried different belt manufacturers, but they all do it. I have also tried belt dressing to no avail. It is only when running the a/c.

Does anyone else have this problem too. Is the only cure a steel pulley?
