weird noise in the engine

This almost sounds like its coming from around the pulleys on the serpentine belt. It doenst happen all the time and doesnt seem to effect the driving.

Re: weird noise in the engine

Does it get louder/more frequent as the RPM’s increase?

No. Its very infrequent. In fact, I dont think I can even hear it when I'm driving. Just idling.

Sounds like a bad bearing to me. Now, which pulley? You could try removing the belt then spinning each by hand. See if you can feel anything.

You're correct! Turns out I had 2 bearings going bad. I just replaced the water pump because it had a little play and the noise was still kinda there. The tensioner pulley is the pulley thats still making the noise. Can I JUST replace the pulley or do I need to replace the entire arm?
