Re: Vintage Air Top Mount Squeal

I went through a period of belt squeal on the donor 99 Trans Am. The consensus was cheap belts and weak tensioners followed by aftermarket brackets flexing on modified cars. I searched High and low for something without spacers. This one (LSX) is expensive but a nightmare averted is priceless. I had already bought a cheap belt so mine was squeaking. I mimicked the more expensive belt by carefully cutting angled grooves every half inch in the belt I was gonna toss anyway with my 4" grinder. Yes it was tedious but I had nothing to lose. It worked great. I will look for belts with those extra grooves from now on. Funny, my 94 serpentine system never makes any noise even with the crappy belt.
