How do I find a squeeking pulley?

[ridiculously_necessary]

any ideas? its loud, very loud, but i cant tell which one it is. i am suspecting the tensioner, but dont want to go replacing pulley's until i find it. the belt is fine. i have had the belt off and all are quiet, its only when the pulleys have tensionon them.

you can buy spray on product that will stop it ie CRC BELT GRIP

soap and water will normally get it to quite down. lightly spray each one it until it stops squealing.

Yeah X2 on spraying it with something to see which one stops the sound. Windex, wd40, soapy water, whatever you want to use like that as long as you aren't getting the belt - only hit where the bearing is in the pulley. I could feel the play in my tensioner pulley and it only made noise first start of the day. I replaced it and the idler pulley at the same time - with a new belt. It wasn't even that much and I considered it cheap insurance.

Good luck!

I use one of those radio shack sound amplifiers (hearing enhancer) tied to a stick. Then I move it by each pulley until i found the loud one. They only cost 10 or $15 from what i remember.

Ha or like my gramps used to do - listen through a piece of solid wood or screw driver. That works like a charm when it's pretty darn loud.

That doesn't work if there is no spot to rest the wood, and is dangerous to be that close to a belt. you can use that "mechanics stethoscope" to hear rod - piston or valve issues. You can use a piece of tubing instead of the sound thing, but the sound thing is pretty easy especially if you don't have a nice piece of vacuum tubing, ground down to fit in your ear, with a piece of coat hanger electrical taped to the end so it will hold the shapes you bend it to. I don't like spraying wd40 or other oils / lubes because it can get on the belt and make it slip.

usually under the hood of a chevy cavalier

i heard the wood things from someone, i can get it on the center bolt and try but makes me kinda nervous.

i tried wd40 on a few but to no avail. i may stop by radio shack and give that a shot. it can detect this with all the loud clatter and everything? its almost deafening with jsut the hood open...

you might wanna be sure its not ur belt. i had the same problem, i replaced the tensioner 4 times. so i went to auto zone exchanged there cheap belt that i bought and bought the more expensive one and no more squeak. mine sounded like birds chirping very loud
