      First time posting here, wanted to thank everyone for their awesome input. I have a 2005 4.0l v6 that's just started squealing again. I've replaced idler pulley, tensioner, and the harmonic balancer when it separated about 4 months ago, and it has a new continental elite belt (similar to gatorback). Engine was smooth and quiet until a couple weeks ago.

      No indications that alternator, water pump or power steering pump is failing (no leaks, overheating or battery problems) The belt squeals only on cold startup then goes away when the engine is warm. It's not a belt or alignment issue, did the water spray test and squeal remains the same.

      I've removed the belt and spun the pulleys and none are loose or spin too freely. They all feel like they have the proper amount of resistance. My thought is that either the water pump or power steering bearings are going bad, but not the pumps themselves. Any help is appreciated

      How long does it squeal? You confirmed it’s not present without the belt?

      Facetious, or serious? I think anything in motion having frictional contact with something else probably can squeak. Clutch has bearings in it, like alternator, tensioner, idler, water pump, and all have been known to be able to squeak.
