2002 highlander--started squeeling from the belt area in Feb. Had belt replaced, was worn. It would squeel on starting then stop. Now turning on a/c makes it squeel. Fan works and after a little while

try cleaning the cogs that the belt runs around some times the belt puts a layer of rubber on them when the belt slips which makes the new belt slip if not could be a bearing in the pullys the belt runs around

Hello, not sure what happen but, on my way to work today my battery light came on and then went off right when I got to work. When I left work later that evening, not only was my battery light still on,...

you may want to check your crankshaft pully to make sure it does not slip. we were having the same problem with our 2004 kia and the crankshaft pully had lost its pins. so it was just spinning on the crankshaft bolt. its the center pully, the one comeing driectly out of the motor. we found this by opening the hood and turning on the a/c. the drag from the belts turning the a/c on. made the belts squeel slightly and you will see the pully slip under the load of turning on the a/c this takes 2 people. you want to start the car with the hood up a/c off and while the second person watches the center belts and pully have the driver turn on the a/c if the belts squeel or the center pully slipps thats your problem.. also if you have any problem with power steering, lights going out or dimming, battery going low or any function light coming on inside. thats an indicator of this also.. i hope this helps you...

I have a 2001 Sonata. I have a squeeling pulley.

It sounds like you have a worn or streched belt making the sqeeling noise. Whenever you turn on a
device in the car that draws a fair amount of voltage
ie. a/c or headlights it will cause increased drag on
the alternator and if you have a loose/worn or glazed
belt, it can slip around the pully making the squeel.
To adjust the alt-a/c belt loosen the mounting bolts
on the tensioner, then use the adjuster bolt behind
the tensioner pully to loosen and tighten the belt.
Be sure to check the belt for cracks bald spots etc.
While the belt is loose spin the pullys to make sure
they all spin freely. Also I would replace the belt just
to be sure. Hope this helps

Sounds like the tensioner bearing is frozen, not turning at all. You need to remove the belt and see if it spins.

2005 nissan ultima.hear a squeeling noise.its worse when ac is of

sounds like to tightened the belt to much... back off the tension on it a little bit, with the belt, you want it tight, but not to tight,,,, it should have about 1/4 flex in the belt when tightened... make a little loose and see if you still have the squeel... if you still do try going to a parts store, like pepboys, autozone etc. pick up some brake cleaner it will be in a canaster, and while the engine is running spray a little <spirts> on the pullys, and see if the squeel stops, if so then it could be a bad bearing in the part... see what makes it stop... the brake cleaner will dry quick and not ruin anything cause you do it in short bursts do not use wd40 or any oil type of stuff on it cause it will cause slippage...

98 mercury villager power dteering noise and hard to turn

The squeeling noise you hear could be the bearings in your power steering pump, when bearings go bad they tend to make a squeeling noise.
