Grinding/squealing noise from serpentine pulley
Today I had an issue I haven't had before, I started the car and was getting a loud squeaking almost grinding noise. Isolated it to the upper right pulley on the serpentine belt. I took some 3-in-1 oil and lubed the hole in the center and behind the pulley as best I could.
This actually eliminated the noise! My question is has anyone had this happen and will the squeak come back quickly? Is there a better method to fix it then what I did? I have 64k miles.
