    No matter how tight or lose i get it the noise doesnt go away. I pulled the belt off and spun all the pulley's and they all seem fine. I did find part of the old belt lodged behind the waterpump pulley but i pulled that off and took all the peices out and that didn't help any. The waterpump isnt leaking and doesnt have any play in it so i would assume it is fine. Noise sounds like the power steering pump but the pulley is fine and im not having problems steering so i am at a lose of what to do.

I might not have enough information but the squeal is most likely a worn bearing. Try to isolate it with a "mechanic's stethescope" to locate the source. A pin point shot of WD-40 at the whining bearing (NO NOT put it on good bearings should TEMPORARILY quiet it IF it is a bearing. DO NOT overspray, just at the center of the pulleys...the lubricant should get pulled into bearing to confirm that the pump (power steering would be my guess) needs replacing.

Try removing the belt and turning each pulley by hand. If everything is smooth and free, with the belt still off, drive down the block once and see if the noise is there (this will eliminate all rotating accessories on the front). If you hear the noise, then there is a problem deeper inside. Oil pressure is good? Dont' forget when doing this, you will have no power steering, so be careful.

SOURCE: My Serpentine belt is squealing above idle

first thing you need to do is get a new belt that belt dressing just destroyed that belt that stuff is no good then get a new belt tensioner clean all the pullys with some brake clean then install the belt tensioner and belt if its still sqealing there maybe a pully making the noise to check that when you have the belt off spin them by hand and listen to them and feel for any play in the bearings

My bottom pulley squeals real bad i dressed the belts and they stopped for a lil bit, the belt is snug. is there anything i can do to quiet the pulley on the bottom of the motor?this is a 97 jeep grand...

Is it possible that the belt tensioner is the cause for the squeal or possibly the belt itself needs to be replaced. Although not impossible, the lower pulley usually is not the cause for belt squeal, unless it is damaged.

2005 grand cherokee squealing and loss of coolant

Check belt tension, squeeling is most likely due to belt slippage. Have you noticed any fluid leaking from under your Jeep? Coolant level drop could be from bad water pump, when the pump needs replacing, water flows out of a "weep hole". It could be leaking onto your belt also, causing it to squeel

Tech says serpentine belt needed to be replaced. after changing the belt 2 more times, still cannot use air conditioner or defrost due to loud squealing from belt and it pulls power down from alternator....

Your vibration damper may be going bad!
It sounds like a belt problem....but isnt load sensitive right? Yeah....that's what they sound like. Especially the part where they squeal on start up.

Have the tensioner replaced too just in case.

My jeep grand cherokee started overheating at idle

try the water pump - first - make sure the radiator is really full - take the cap off cold and fill - if it looks full - start and run 8 minutes or so - then fill it up - look at ur fan belt - is it tight - tight is about how much pressure u use to make a firm hand shake with little movement - any movement over about an inch is loose - when the jeep warms up the belt can slip and not even make a noise - - new materials don't always squeal. - then be sure ur water pump is ok - they go slowing - the fins wear down - one more thing is the radiator - u don't say how many miles or what maintenance schedules you have or not so that's it for now

My 1999 jeep cherokee belt squeals very loud when giving it gas and chirps a little when idleing

If you get the squealing noise even when car is not running, and if noise get louder when you push the accelerator pedal, then it is the serpentine belt.

You may need to put the belt in tension, or to replace it.
