Angry my belt squeaks

i got a 91 jeep wrangler and everytime i start it up it squeaks for about 30 seconds except when its really cold out. i replaced the idler pulley cause someone told me to but that still hasn't helped. i've read it just needs to be tightened but i don't know how to and i don't wanna pay a mechanic an arm and a leg for it. also the belt is only about 4 months old. can anyone help? thanks.

Loosen the bolts on your alternator and tighten using that. That is how I remember mine working, anyway. Maybe someone else knows from more recent experience. (I did my '91 YJ about 6 years ago.)

If you have to ask what it is or what it does, you don't need it, and you will need help to install it!

Hey Karl, check your belt and make sure it is loose first..you should be able to put your finger or two fingers on it..and push it a little..you should only be able to have about 1/4 to 1/2 inch of slack in it...if that is ok...sometimes the belts get a coating on them just from use...go to a auto parts store..discount auto or something similar and buy a can of belt dressing. Just spray a little on the belts and start it up...that should take care of the problem, unless it is a loose belt..that will have to be tightened..

I will Second this. Tried new belt and adjust/tighten....no good. Tried Belt Dressing (many times)....no good.
My trouble is Intermitent.....seems to happen if I leave lights on, other times for no apparent reason.....sometimes it's only a few seconds...others it SQUEALS LIKE A PIG for a mile or two down the road. Wet, Dry, Cold, Warm........doesn't matter when it wants to squeal it does. I have gotten used to it... but.. If someone has a good fix I will try it too!

The tension adjuster on my 92 is under the power steering pump. It pulls the power steering pump over to tighten down the belt. I would assume the 91 is the same.

If it is happening intermittently with no rhyme or reason, I would guess that something is going bad, either an alternator, a power steering pump, or a water pump that is causing it to seize, and therefore squeal as the belt is dragged across a non-moving part. Just another (hopefully wrong for your sake) thought!
