I don't why but my belts squeek like hell. I tried to tighten the tension pulley but that only fixed it temporarily. The funny thing is that the belt stops making noise once I push the clutch pedal in. Is this because its taking load off of the motor?
When my car is just idling at a stop they squeek, but as soon as I push the clutch(no revs, in nuetral) it stops. Dirty belts? Not tight enough?

 

I've been having the same problem as you. It could be old belts but I've sat listening to them with the hood open idling and I think it could be something else.

 

The end play of the crank is taken up when you press on the clutch pedal. It may align the crank pulley just enough with the accessory pulleys to alleviate the noise from your worn belts. How much end play do you have is the question?

 

End play?

I only need to push in the clutch pedal about an inch.

 

EUREKA!

throw out bearing making noises. I can manipulate the sound with the clutch pedal, so it can only be one thing :clutch not belts.

Too bad I now have to drop my transmission.

 

yeah my throw out bearing has been squeeking for about 60K miles...i wonder when i should replace it :P

 

there is something called belt ease it's a spray that u just spray on and the noise goes away, not saying there might be other problems tho

 

why is that a way to shorten it? it just makes the noise go away....
