Default Engine compartment rattling noise

2016 Lexus IS 200t . 128k miles. Base model.

This rattling noise started going on at idle and it keeps going on whether the engine is cold or at normal temperature. I just replaced the water pump, due to minor coolant leak , and the rattling noise it still there. Has anyone encountered this before. There are no issues with engine driveability or CEL.

unfortunately solara didn’t answer your question. He just made a silly retort to say that he traded into IS350. I would go have that looked at to get a diagnosis. It does not sound normal.

Agree, that does not sound normal at all.
