So I did some studying on this belt situation. It seems to be a pretty common problem and for the most part like many internet searches, way more questions than answers. Its always fun trying to weed through the arm chair yahoo responses but after quite a bit of reading I came across one that seemed to make more sense than most. "The squealing noise is the belt grabbing then slipping over and over again. It is a misconception that you want the belt to be "sticky" to grab the pulleys better. This actually makes the issue worse. As the belt wraps around the pulley it will always stretch and move on the contact surfaces. The "stickier" they are the worse the squeak. Think of wet sneakers on a tile floor. At the dealership we would hit the belt with brake clean, hit it both sides with a wire brush and then put a small dab of the silicone high temp brake grease on both sides. Just a small dab on the tip of your finger. The belt will still slip a bit because that is simply what a belt does, however it will now do it with no squeal. And it is a lasting fix. Side note though, make sure your pulleys are clean and lined up correctly. If one is out of line it will squeal all the time." We were headed for a cruise night last night so I took the belt off and we gave it a try with the current belt. I reinstalled it and no noise for a bit but just as I was loading the car, it came back. No where near the original sound level (which was horrible) but still a squeal. I did pick up a smaller belt, 3/8 width versus 7/16. I decided to give it a quick try and slapped it on. I fired it up and the belt ran with no noise at all but upon reving it a bit, immediately twisted itself over in the pulleys. LOL I decided since we had a measurable change the first round maybe we would give it a second try. So we took the original belt again repeated the process. I spent a bit more time with the wire brush this time and we reinstalled it. Not a peep. No sound what so ever even at high revs. We ran the car quite a bit last night including a quick cruise or two still no squealing!
