Squeak from Serpentine Belt Area

[black tahoe 08]

I have an 08 Tahoe, new to me about 2 months ago. The serpentine belt is squeeking and I can't figure out how to stop it. I have changed the alternator, idler pully, tentioner, tensioner pully, and belt. Still driving me crazy

Welcome to the forum from Oregon.

I am gonna go out on a limb here. The belt is not squeaking. If you take the belt off and start the engine, is the noise still there? If it is, maybe the noise is related to the a/c. If the noise is gone, maybe the water pump has a noise.

Welcome to TYF!

Moved you here from the Midwest Regional Forum.

Be sure to remove the A/C belt, too.

My 2005 has a squeaking A/C clutch bearing. As I tell people, I have a tweety bird under the hood!

As mentioned, put the A/C belt and see what happens.
