1991 300e coolant type
 

hi i just bought a 1991 300e 3.0, and the còolant it has in it is the green stuff. is that right? b/c i got a 94 e320 and the coolant is orange.
thanks

Green = Prestone = bad! Get some Zerex citris flush. Drain at radiator and engine block drain, Then flush with heater/defrost on. Drain again until all is clear.

Get some MB orange stuff here from Phil (best price!), distilled water and
one bottle of Red Line water wetter. Here in the South I run a 45 antifreeze 55 to distilled water mix.
