Thread: Belts are squeaking when the engine is running. How should i stop this?

Take a look at the belts. Are they off/out of the proper grooves on any of the pullies? If so..loosen and fix.
With engine running, dribble a few drops of water on the belt. If the noise stops, typically it's a belt that needs to be replaced.
If that didn't help it. Check all your pulley bearings, rotating them by hand and feeling for looseness. Replace as needed. If that doesn't work, it's usually a tensioner.

If you want it quite for a few minutes, use belt dressing or soap.

x2 on the tensioner.....I'd start the search there.

I've found that when a new/good belt squeaks, cleaning it off all around with a wire brush can resolve the squeaks sometimes.

Just had this issue with my car. I just ended up throwing an old belt I had laying around and it stopped the chirping all together.

it squeels, if the belt has alot of cracks in it, if the grooves of the belt are worn down.

replacing the belts yourself is easy, just use a 15mm wrench on the tensioner pulley to loosen the belt.

I hope it works for ya. The good thing is that you can always return the belt if it doesn't resolve the issue. Don't forget though you have 2 belts(one for the S/C and one for the accessories). So you need to figure out which one it is.

X3 on the Tensioner, but check the other pulley's or wind up with this... I changed it out the other day after crazy noise started from nowhere only to find it in pieces when I opened the hood. Luckily I made it home without any problems... lol

If they were squeaking when the car wasn't running I would be really worried

sounds like it could be a bad idler or tensioner, remove the belts and turn the pulleys to see if one squeaks or has excessive play in it.

when you have the belt off, look at the groves, bend it, if it has cracks you will see them clearly.

Sounds like a squeaky pulley. Could take off the belt and try them all. Pulleys are cheap and all autoparts stores carry them. nbd.
