Squeak sound from belt

[cashville]

I got a noise on idle, and specially on acceleration that is coming from the belt (i've tried a method which is using a candle wax on the belt, the noise went away for a minute but it came back, so I know for sure it's coming from the belt or some part related)
Before replacing the serpentine belt, I would like to try other methods to see if i can remove the noise, because the belt doesn't seem that worn out. Maybe the noise is coming from the pulleys.. Anyway I can isolate the noise with some tests, so I know the right parts to order?

Had the same problem. Replaced the belts but in end it was the pulley. Try lubricating them first.

Where exactly on the pulleys, should WD40 be used? I'm guessing not where the belt moves, because it's not supposed to get greasy there...

Seriously candle wax? Try a can of brake cleaner next time.

Just put on a new belt. If that doesn't solve it, its most likely your idler tensioner pully.

candle wax...never heard of that one before.

It works to remove the noise, but it's just temporary.
I didn't get a new belt yet, because delivery will take 2 weeks, and I don't want to wait 2 weeks to change the belt, and then find out it was not a belt problem, but rather a pulley.

where are you where its going to take 2 weeks??

if your pulley is ****, your most likely going to need a new belt from it slipping anyway.

There is a spring tool to test the tension on the belt.

Hose the pulleys and belt (both sides) down w/ brake cleaner and see what it does. That will actually clean dirt/grease off.

I remember my grandfather used to have a big stick of waxy material (like a fat candle) that he used to call Dum Dum (or something like that) that you would touch against the belt while it the motor was running and the squeal would go away. I tried to Google it, but must have the name wrong, or it was just a nick name for the product that they used around the shop. He used to work for MACK truck and would bring various kinds of random, industrial-brand products home from time to time.

I've also read of people spraying squeaky belts with Turtle Wax Super Protectant...supposedly works better than candle wax.

When you say wax...I just think of the friction and heat generated on the belt and pullies. Wax is kinda slippery, its not tacky. I dont get what the hell thats going to do other than goo up the belt. Holding a bar of that against the belt on a running motor is a good was to loose some fingers.
