    When Im am sitting at a red light my truck makes this squeling noise from under the hood. It only does it at an idle, the moment you give it a little gas it goes away. I just replaced both belts with the gator back belts becuase I had old ones and thought that was the problem. Have any of you guys had this problem or any suggestions? By the way the truck is a 2001 with 87,000 miles if that helps.
    Thanks Brett

    Sounds like it's out of tune. Better trade off that wait for me tune for a Nelson tune so that it sings instead of squeeling.
