good morning gents, i just drained the old coolant (i can tell it's been there for a while!), added 50/50 mix, let the engine run for a bit, drain again, and then added 50/50 mix (OEM MB fluid).
I'm a bit nervous about the MB cooling system coz i do not see an extra reservoir. anyway, i have the heater set at max and i've let it reach operating temperature. how do i make sure all the trapped air is purged from the system? thanks !

Don't you have pressurized coolant reservoir on passenger side in the engine compartment?
You did fill the system, so you have a cap somewhere. Just recheck the level there. MB usually have a sensor waring about low coolant level.
