My 2.4 Cobalt is squeaking when I press the clutch in. It's not terribly noticeable. At first I thought it was a wearing serpentine belt or something like that, but it appears that if the clutch is released 100% it does not make this noise. It only make the noise when clutch is pushed in.

Thoughts? Should I be worried?

 

Is the noise constant while the clutch is pressed in or does it only make it as the pedal is moving? If the noise is constant it is probably the throwout bearing, needs to be replaced and its a very labor-intensive job. If it is only when the pedal is moving it probably just needs some grease.
