I have a squeal that has been awful. OOPS! here we go.
When I start my truck, usually when its cold it happens.
It lets out this horrible belt squeal, I tightened them once.
It seems like an alternator thing, possibly water pump.
Next weekend I guess I will try to take a belt off and let it cool off.
Try it and if thats not the one, I will move to the next belt and try again.
