After my car has been sitting for a while, overnight or after work, when I start it up I hear a faint squealing noise like a belt going bad. The serpentine belt is not even a year old so rule that out. I have also narrowed it down to it only happens while I have the clutch depressed. When I let off, the sound goes away, then press and it comes back. The sound completely goes away once the car is warm.

Any ideas?

Minor detail or should I change that ASAP? I would much rather wait until I needed a new clutch.

 

yeah, I don't see why you cant wait till you need a clutch. unless it gets really loud don't sweat it.
