2004 CLK500
Alright so I’ve noticed that my car is leaking coolant at a relatively fast rate, maybe two days of driving I’ll lose about half my coolant. Also it only seems to drain while the car is running. The leak is coming from the right side of the radiator while facing the car, there is a black piece that protrudes into the silver metal, that looks like it’s where the radiator is held to the car, and it seems to be leaking from there, I will include pictures. I don’t see a hose that could have busted or rotted just some plastic, can’t really tell where it’s leaking, can you guys? Thanks in advance

if I confused you, it’s the first black piece you see when you look at the bolt at the bottom middle of the screen and moves your eyes up
