belt or pully problem, suggestions?
well whenever i start up my truck my belt or a pully will screach, with the a/c off and lights off. now while in idle, if i turn my a/c on it will screach when i accelorate and whenever the a/c clutch kicks in. now after the a/c on and the truck in idle i turn the lights on and all hell breaks loose it will let out an almost continuous screach. anyone know what this is? i recently installed a used underdrive crank pully and alt. pully with a new gatorback belt.
