    Could be a worn belt or the power steering.

    Its not the belt, it's the pulleys. Take the belt off and use a wire brush on them. Theres residue from your old belt on them and when cold it squeeks, when hot it sticks.

    Might not be the same case, but. I had a poor experience with a gatorback belt.
    I needed a new belt for my 92 chev pickup so I bought a gatorback, figured it costs more should be better.
    Belt was on for a week when I started the truck on a 95F day and turned the ac on, it squeeled and then the belt jumped off. I put it back on using a crowbar "was at work" Then noticed the idler pully was almost touching the waterpump pully. I drove home slow but the next day the belt jumped off again.

    I went and bought another Gates belt which was much stiffer and kept the idler much higher up. The gatorback was soft and stretchy.
    Due to that experience, i'll probably never buy another gatorback belt.

    If I were you, i'd go buy a Gates belt and ditch the goodyear one, your squeal will probably go away.

    Cheap troubleshooting.. get a can of "belt dressing" ... not a long term fix by any means.

    belt dressing makes a mess, and yes, Gatorback is a gimmic. Theres actually LESS surface area on them causing them to slip more.

    Mine does the same thing. the accessories belt is new, the SC belt is not. I'll also try the brush thing I guess.

    Mine does that as well but it's all the time even under acceleration, put a new belt on , stopped for about a week, started back up. Changed out the Tensioner on the ACC side and still did it thought it was the alternator, still did it. Sanded down my water pump pulley and that stopped it for about a week or so, and now it's doing it again..


    Any other ideas? It stops for a few miles if i put break fluid on it, but other than that my only other idea/suggestion was to use a gator belt but now that i have read this im going to avoid that idea all together lol

    I just went throught this too only on my sc belt. Check the alignment of the belt and make sure it is stright. Mine was off due to me pressing the mps hub on too far. I was on groove off on my 8 rib pulley.

    Dont put anything on your belt. You just ruined it. Get a new good belt. I have a gator grip and it works fine on my car.
