Every time I start the car there's this noise I don't know how to describe. It's there immediately upon start, during idle, while driving, constant. I have been ignoring it because everything works fine. Yesterday it got significantly worse. Now it sounds like a kitten set on fire or something.
I think it's coming from the belt or one of the pumps that run on it. The thing is, everything works perfectly. Power steering is fine, A/C is fine, no loss of power, no trouble starting, temperature seems fine, if it wasn't for the noise, you would have no idea anything is wrong. While the noise is constant, it seems to become louder when I shift gears.
Should I replace the belt and hope that was the issue or how would I determine the exact source of problem?
