so ive noticed coolant leakage at the reservoiur tank, not at any of the hoses or at the radiator

the cap looks good and seems to be on tight, but after the car is shut off, it sseeems to pour out quite a bit from the cap area

we refilled it with peak green coolant/antifreeze...hope it was the right one

anyways, what could be the issue

the engine temp is fine, 80 c

Sound like pressure in coolant due to bad head gasket.Ma Benz used crappy head gaskets on their gas engines.

u dont think it might just be the cap?

I would check the reservoir itself - particularly where the hose to radiator connects. Mine had a small crack in it and would require a top up every couple of weeks. replaced for about $100.
