I heard this loud rattling from engine compartment. Not sure where it is coming from. When idling or driving it is a constant noise.

Are there any drive pulleys on the engine wobbling? It could be a water pump. If it is really loud it is most likely the water pump. You can also pop the belt loose and see if the water pump pulley is loose. It is the pulley right bellow the A/C compressor. You can also spin the A/C compressor pulley while the belt is off. Let me know what you find.

Hopefully it is not the timing chain.
