Squeaking of belt noise

A use tip for all car owners. no specific model/make.

The Belt of the a/c to the solenoid pulley or the main belts can create a lot of squeaking noise.
Start the car to hear the noise now pour some water into the belt and the noise will subside off . You have the noise confirmed of a belt as sometimes it will trick you to think of water pump bearings, alternator bearings or even engine noises.
Stop the engine and check for play in the belt if so tighten the belt If not use some chalk power or candle wax to be rubbed into the belt that was making the noise - the a/c drive belt - or the main belts..
Now start and check . the nosie would be reduced or gone.
You can have the belts changed sooner or later.

squeaking fan belt


fan belts squeak for several reasons 1 incorrect belt for pulley.2 belt running on the botton of the pulley and worn pulleys. To check measure across the top part of the pulley and the widest part (back) of the belt should be the same if not marginally bigger. V belts work best at t5he top of the pulley.If you can see that the pulley is polished at the bottom the belt is slipping and not driving Check if the pulley sides where the belt runs is not stepped from wear. Recheck the tension as new belts stretch slightly. If you have a multi groove pulley check the tension setting. As a last resort CRC make a product that is used to stop belt but it is best to fix the real fault first

squeaking sound from fan belt


  • Take a can of brake clean and spray it on the belt while it is rotating. If the sound goes away for good it was a dirty or wet belt. If the sound goes away and come back it is more than likely a bad belt. Remove the belt and turn all the pulleys to see if they are spinning free. a stuck pulley can cause a belt to squeal too. If a pulley should catch a bit then perhaps the pulley could be part of the issue as well. Should all pulleys check good then put a new belt on. Don't forget to check the tension pulley for weak springs.

I have a brake sensor problem. I read one of the comments about setting the ignition to position 2. I tried it but did not work. Am I doing it wrong? Second problem is... one of my belts squeaks in the morning when car is cold. I was told it wasn't the belt but rather the pulley. Not sure if it hydraulic or mechanical.


i expect ur engine 24v. this model use one long belt and one short belt. the pulley cammonly not the cause. when belts is squeaking ur pour some water to those belt and find out the hot belt. the hot belt will vapourise the water. the belt should be replaced. before replace check for free running of each pulley and clean the pulley surface. im suggest place with continental belt.tq

AC Belt squeaks on my 2002 Lexus es300


When belts squeak it's either from dryness wear or tension / tightness / looseness affecting alignment.

Check for tightness and you can spray with belt dressing and try some WD40 on the compressor pulley.

If none of that doesn't stop it it very well could be the clutch or pulley is stiff from non use and could need replacing soon.
