Agree, most likely something driven off serpentine belt, but ID'ing it is tough on serpentine belted.
Take a length of garden hose or any type of hose about 3-4 feet long or any length convenient for you. Hold one end up against your ear...some times put a funnel into it and hold the large end against the side of my head...sweetie thinks the neighbors will think I'm wacko... :) Poke the other end around various rotating shafts/bearings while the engine is running. CAREFUL to not get tangled up with the rotating stuff & serpentine belt. I have a length of copper tubing hose clamped to the "poke" end to allow better manipulation and can actually "touch" stuff (like the bearing housing).
Or you can buy a stethoscope with hard rod prob. I like the hose better as you can't touch all the time.
