Default OM642 Coolant Change.
Hi Gents.
Planning a coolant change on the Jeep.

If i just drain the system by removing the coolant tank cap, and then opening the radiator drain tap, how much coolant will be left in the system?

Any special way to refill to avoid air locks?

Incidently, the Jeep has the blue Mercedes coolant in it, so i will be using the G48 stuff.

Thanks.
