Squeaking noise from the engine.

Squeaking noise from the engine.

Postby ppoopruitt1 [OP] » Mar 07 2011, 4:32pm

I have a squeak coming from my engine. I already replaced the serpentine belt and it is still doing this. I'm not sure what it is, maybe another belt? I don't know
If anyone knows or think they know please help. Thank you.

It could very well be a pully...when the bearings wear out they will wobble just enough to get a lil squeek going.
Crap, my hampster fell off the wheel and it broke its leg.

Could be any number of the pulleys. Could also be the A/C belt. You have to get under the hood and listen around to know for sure. If you can't narrow it down to any specific pulley, I would say try and replace the A/C belt

Ok say it is a pulley. Is it better to just replace the whole pulley or the bearings?

Yes, just for a quick test in the driveway.

I will definitely try this, to narrow down just what it is

Whenever I would walk by my truck, when it was running, the engine bay was always noisy. I could hear the belt squeaking, so I changed it- and everything seems quieter. Hope that helps...

you can buy the pullies they are very inexpensive. The bearings are pressed you cant replace just the bearings
