Squeak/Chirp from accessory belt...

Squeak/Chirp from accessory belt...
I've noticed a weird noise coming from my belt. It seems to be around the alternator. It's pretty quiet at idle, but when I rev it the noise gets louder. However, if I spray some wd-40 on the underside of the belt wrapping around the alt's pulley, it goes away for about 10-15 min then it slowly comes back. Bearing, worn belt, rock, or somthing in the pulley?

Probably the idler pulley bearing. Put a large screw driver directly on the center bolt while the engine is running and the other end against your ear. You'll hear the bearing making noises if it is bad. Be very careful not to touch any moving parts!
It only costs about 10 - 20 bucks. You can buy just the pulley with bearing or the entire spring assembly with pulley. Either are readily available anywhere.
Spray WD40 right in the pulley center to see if quites the bearing. If it does, you know it is bad. Don't get it onthe belt or it will slip.

why go to a shop man?
go to the parts store and buy a new belt tensioner pulley, or the whole assembly, because its probably on its way out too. Then get under your car, put a 13mm on the belt tensioner pulley, turn clock wise. That will relieve tension. Take the belt off and then you can let go of the 13mm. Then you need a 10mm, theirs 2 bolts, 1 on each side of the tensioner. Take them out, the belt tensioner should now be free. Then just replace with your new one, make sure to lock tight the bolts.
If you just replace the pulley, leave the tensioner on the car unless you have air tools, and just take the center bolt out and then replace with your new pulley.
its a 15 minute job, 30 for a first timer.

Yeah I could do that myself, I just wanted to see what they say. But after thinking about it, there is a good chance it's just the belt cuz when I spray a bit of wd40 on the belt, the squeak goes away instantly. I'll pick up a gatorback and put it on and I'll let you know if that fixes it.
