Belt slap on the alternator belt. You can see it on the lower left of the water pump pulley.Anyone want to chime in with what they think this might be? It sounds like it's coming from the outside of the front of the engine, around the pulleys.
Thanks in advance!
Thanks for the reply! I had the idea, reinforced by Scott06, to take the belts off and run it. Will report back for others' reference.Belt slap on the alternator belt. You can see it on the lower left of the water pump pulley.
