I started my car up this morning and it made an awful screeching noise from the engine, sounded like it was coming from the belt. The noise went away after I drove the car for a few minutes though. I know it isn't the throwout bearing, this was definitely something different--could the belt just be squeaking because of the cold weather? It hasn't done this before and I didn't notice any major cracks on the belt surface. Any ideas would be appreciated as I really don't want to pay a dealer $75 just to tell me what the problem is and then have to pay to get it fixed from there.
