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.

Sounds like a loose belt, but which one I don't know. My truck did something similar, and it turned out to be the alternator belt.

Also, how do I tighten the belt? The noise doesnt re-occur once the truck is started.

On each of the belted items PS pump, AC , & Alternator there are pivot points
Look for a bracket toward the bottom of each of the above items, the bracket will have a bolt head visible as you stand in front of the engine - this bolt holds the adjustment bolt in place-
This will need to be loosened to make adjustments. Perpendicular to the that locking bolt- you should see a longer bolt which will actually move each respective pulley either toward or away from the fan pulley as you turn Clockwise/C-Clockwise - You willl also need to loosen the bolt that serves as the pivot point

They all adjust in similar manners
The easiest one to see is the alternator - Loosen the bolt up to, loosen the bolt below on the bracket, then turn the long bolt to essentially move the pulley .

Since I put a new Power Steering pump on my truck has a quick squeel when its very cold out on initial start up. I dont think it is my belts because I paint marked everything prior to disassembly, go figure.

You start hearing all kinds of diffent noises when you first crank your truck and it`s real cold outside. Belts will sometimes do that. Let the engine warm up a bit and then shut it off and re-crank it. If it doesn`t do it again then you know that`s it. You still may want to check belt tension though.

check your belts they stretch a little at first. If it squeals just for a second when you start it up and goes away I would look at the alternator belt but you should check all of them while you are in there.

Thanks everyone, i am going to get out today if i can to check it all.

I'm placing my bet on a bad front bearing in the alternator.

I'm placing my bet on a bad front bearing in the alternator.

would you have start up squeal? or drive around squeal?
how do you know if the bearing is shot?

another vote here for just a simple lose belt...check em all and tighten them up.
