I have replace the serpentine belt and both idle pulleys and it is still ticking and squeaking. I poured water in the belt before and after replacing it and the noise stopped each time. I am not a mechanic, but could this noise be a warning of something major about to happen,AGAIN. I just spent $2000.00 due to low/no oil pressure. Also, it was not making this noise pryor to the oil pressure issue. Does anyone have any more suggestions?
