Also, it sounds like its noise is consistant with the engine turning, aka, something that is belt powered, and intermittent, so that leaves Ac clutch pulley and alternator, since both don't run 24/7 but in cycles. Alternators however can be heard phasing through the radio, and otherwise are not audible even when failing.
I agree that it sounds consistant with the engine turning. It's just that it was pretty loud.... it was louder than it seems on the video... lol

Thanks for the details. I'll follow up after I meet with them next week... hopefully with the problem solved even.
