Because if its coming from there then you need to replace the compressor... $$$$$$$$$$
Are you $600 confident its coming from there? If so, replace it and see if the squeak goes away. Don't know what else to tell ya other than what I already did.... I'd spend $15 on an automotive stethoscope to be 100% certain that's the true origin of the noise because its not a cheap fix. Actually, its winter.... I bet They make an AC delete kit that would be cheaper...
AJ, what happens to the noise if you turn the AC on full blast right after you start up?
Water pump seems plausible.Originally Posted by cico7
The squeak is present, unless you want to know whether the frequency of the squeak changes. Squeak more, less, or unchanged - but I will find out.
My dad had a Cherokee sport with 4L that started squeeking. He thought it was the pulley. He bought and installed a new pully. It still squealed.
I asked why they didnt replace the water pump....cause it still squeaked. He had the pump replaced, squeek (squeak) gone.
If the squeak doesn't change significantly when the AC compressor clutch engages, then its probably not the compressor. Engaged vs disengaged is a different set of bearings and also rules out the clutch itself. So that would be a good test for peace of mind.
Expect the frequency of the squeak to change though because engaging the AC clutch will cause a fluctuation in engine RPM and load on the belt.
Let us know how it sounds.
I'll repost this - it didn't load correctly.
When the compressor engages - it squeaks louder. When I started the vehicle with a/c max it was loud - I tested it while driving and any time i turn on the A/C it comes on. It's my AC Compressor.

You must of messed up because I can see if it was removed and there's nothing there.
I dont think it was removed, I think i doubled tapped it on my phone and then driod freaked....You must of messed up because I can see if it was removed and there's nothing there.
AJ, I hear your words, read the print, but I still think it is the water pump....
I'm leaning towards this as well since it seems to go away after 10-15min..... engine heats up, tstat opens, less load on impeller. Due to its location in the block, it could definitely sound like its coming from the compressor if you're standing over the motor.
