This problem started out of nowhere and I can't figure it out.
There is a loud chirping noise coming from the front part of my engine. At first I thought it was a pulley going bad or the water pump, but I took the serpentine belt off and ran the engine for a minute and the noise was still there.
I've heard that this might either be the cam sync, or the harmonic balancer but I can't tell for sure. Everything seems to run fine, and before I make any costly repairs I just wanted to see if anyone has had a similar problem or input on my situation.
Thanks in advance.
