...coming from the pulleys? the loud knocking sound scared me because it is very loud and thought the worst, crankshaft. I brought it to guy about 20 minutes later and asked him to tell me what he thought it was. He asked me 2 start the engine for less than 3 secs wit out the serpentine belt on and sound was gone ruled out crankshaft he told me he believed it to be water pump. i changed water pump and same thing. Then realized pulley on power steering pump had some play in there and if i did it by hand sounded like could be sound but changed it and same thing. that only leaves two things ac compressor or tensioner pulley. If i turn ac on all the way up sound really quiets down so i am thinking is ac compressor can someone please give me a better idea so i dont change ac compressor if it doesnt need to be.
i have taken belt off and shaken all the pulleys that is why beleved it was the power steering pump.
