Question about 2001 Hyundai Sonata

1 Answer

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

I have a 2001 Sonata. I have a squeeling pulley. Is it the idler pulley tensioner pulley? If I start the car cold it squeels. If I have the fan on while driving it squeels. So what I have been doing is turning off the fan and the squeel stops. Then I turn the fan back on with the A/C. When I come to a stop with the A/C on and start to take off it squeels. Turn the fan off it stops then I turn the fan back on. Is this the idler pulley making all of this squeeling? How do you take it off. My manual has no procedures on belts or pulley changing. Where do I get this information?

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

1998 mitsubishi eclipse spyder. alternator belt squeels. no wiggle on any pullies. new belt tight. battery light stays on dim. parking brake stays on dim. what could be the problem


Belts should have a half inch of play on the longest distance between pulleys...when you push down on it with your finger...not too tight or too loose.

Check the tensioner pulley and others for wear in the bearings as they can wear and fall apart...

Check for shiny spots on the belts for wear..also, Usually a bad or failing idler pulley will produce a few symptoms that can notify you of an issue.

Visibly worn pulleys. One of the first symptoms of an issue with an idler pulley is visible wear on the pulley. ...
Belt squealing. ...Damaged bearing or pulley. Like the belt tensioner pulley, it's designed to remove that annoying belt vibration that's caused by excessive belt slack. The only difference between them is that the tensioner is mounted on an adjustable bolt, while the idler pulley isn't..... cheer's

Squeeling belts toyota avalon 2006


There are several possible reasons for this. The new belt may be the wrong size or have a different number of grooves cut into the belt. Some pulleys have more or less grooves which must match the number of grooves on any grooved pulley, even if only 1 pulley has the grooves.

Mounting the belt through different paths which makes slack in the belt.

Frozen or worn Belt tensioner which fails to put adequate tension on the belt. Idler pulley bearings can be worn out and new belt is now causing bearing to show up with noise.

When routing belt, make sure grooved part turns on grooved pulley and not the smooth backside of the belt.

Squeeling after replacing all belts and the tensioner pulley?


Still sounds like the belts, not much will cause that type of noise. You can completely remove all belts and start engine to see if noise is still there, no harm to engine to run it for a minute or two with no belts. You will know for sure then.

If for any reason, the tensioner is crooked, replace it!!! Also, install the belt with the writing facing you like you are trying to read a book. This WILL (a trick I learned at Mercedes) prevent even a new belt from squeeling!!
