Help needed diagnosing a chirping noise in the engine bay!
Hello everyone,
I've recently purchased a 2000 Mustang V6 with 160k miles as a project, but I'm loving it so much that I have a feeling it may end up be my daily driver soon. Now, it has a few things that need to be fixed, but the most urgent thing is this annoying chirping noise that I can't for the life of me find out what it is! I originally thought it was the belt tensioner but replaced that to no avail, and the previous owner thought it was the water pump yet that still hasn't done anything to fix the noise. The only thing I can think of is that it may be the camshaft synchronizer. I embedded videos, and as you can see from the interior view once you press on the accelerator the sound goes away a bit and comes back down once the car starts idling again. Any help would be greatly appreciated! Thanks!

The A/C has no affect on it at all, and the stethoscope really didn't help much because everything it could be is all in the same general area ie. Belt tensioner, water pump, camshaft sync. I'm starting to think it's the camshaft sync since the water pump and belt tensioner have both been changed, but I wanted a few more opinions before I try and change it out.

Also, it sounds exactly the same in person as it does on the video. The wind noise messed it up a bit but it's almost a pretty good reference.

ok, so you changed the belt, you changed the tensioner, you changed the water pump and when the A/C is on the sound doesnt change?
you couldnt pin point anything with the mech stetho either?
The sound increases and goes away with the rise of RPM's.
Alright so that leaves the top pulley, the alt, the ps pump and the CPS. Dont rule out your A/C though, the pulley is always turning.
To be honest, from the video the chirp was loudest when you went over to the A/C.
Also like said before, starting the car for a very brief moment will prove or rule out the CPS. Do this when the car is cool too and have a set of jumper cables handle just in case.
With these things it is just trial and error.
