2008 Hummer h3 engine or fan belt squeaking noise
 

Hi all,

Can someone help me figure out the potential cause of this squeaking noise? It happens when idling or driving, not very consistent, comes and goes.

Here's a quick video:

Thanks!

Thanks for replying! I just tried WD40, didn't help. It actually made the squeaking louder. But I noticed the rad fan pulley is shakey and misaligned. See video below:


Looks like it needs to be replaced. Should I replace the belt at the same time? Currently at 58k miles.

Remove belt and check for play in the water pump pulley. I found play in mine, perhaps too late because the fan clutch was a bit sloppy too. It's reasonable that one exacerbates the other. Replaced both in mine and now no noises.
