I can't find any information on how to flush and fill the low temp coolant. I am not sure it is for the intercooler but it is the tank at the top of the engine that holds coolant. Coolant tank on top of engine in front of the turbos
Anyone done this and can give me some directions on where the drain is and what the pressure specs are to vacuum fill this system?

Reason: added info
Does anyone check this coolant tank and do you need to add to it occasionally? Mine was empty so I want to flush the system. Anyone know where the drain is for this system? I can only find a video on an older S class and this is different.
