Recently my truck has begin to give a little squeal when I start it. it is coming from the drivers side of the engine compartment (I think). It sounds like a belt squeal. My belts were replaced not to long ago (30k). Could it be the PS pump if the belts look OK? Also, how do I tighten the belt? The noise doesnt re-occur once the truck is started. I am worried it culd be something I need to address real soon, I want to go wheeling in Paragon PA on Sat, but i dont have much time to work on the truck befor then.
