I have 82k on my car and it just started as well it is reall flippen loud and I have noticed it is coming form the back of the engine and I thought it was the belt on the backside of the engine so I replaced it and it is still there this happens even if the car is standing still i am replacing my water pump tonight thinking this is what is making the sound so i will let you guys know tomorrow if that is what it was but it is bad.
