The issue at hand is a vortech s trim blower (loud version) and a stock 5.0 motor. When i start the car i hear a squeel but its hard to find where it is coming from over the sound of the blower. Everyone i get to help says its the blower but its def. not. The squeeling only occurs at a start up for the initial start up ( like 3 seconds) then disappears until i start it again. Sometimes will not do it when hot. Also put a new belt and belt tensioner on because i thought that was the problem.
