Good walk through.. Your video is helpfull. I have the same car and engine. Something near my water pump sounds like shakin a box of rocks when the engine is idling. I will take the belt off and check all the pullies for loosenmess. I also got a check engine code 42 around the same time the noises started so it might be the harmonic balancer.
We didn't see the part on the pump. Is that a pully in there?
