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

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.

Replace serpentine belt



Removal & Installation

  1. Rotate the drive belt tensioner clockwise and remove the drive belt.

  2. Rotate belt tensioner clockwise and slip drive belt over idler pulley on tensioner.
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!!

Found tensioner pulley was bad and changed it. Still squeeled and engine would stop when squeel got loud. This time while sitting in yard. Further checking found binding in power steering pump. Will be putting on new one tomorrow. Hope it works. Will update.
