Some background... I was getting some high pitched "squeals/chirps" from the front of the engine after driving for awhile. Nothing at cold start and only would hear it if I was stopped at idle. It may be happening when driving but I can't hear it if it is.
I sprayed a little water, noise went away, so I thought it was the belt. Replaced the belt and was good, but then it came back.
Replaced the two idlers and tensioner assembly and was good, but then came back. One of the idlers had some wobble to it so I thought that was the culprit but, apparently not.
After driving 20min or so I sat in my driveway at idle and cycled the A/C, turned the steering wheel (P/S pump), turned on the heated seats (Alternator), etc to see if I could hear any difference in the noise. No change.
Water pump, perhaps? I may yank the belt and feel the pulley to see if there is any lateral motion detectable. I've also heard of belt alignment issues on these engines. Usually turning on the A/C would detect that, however.
I have a video of the noise but it's too large to load. I'll try to edit it down so I can get it attached...
