Coolant drain and capacity (N63TU)
Changing the charge air aux pump, need to drain the coolant.
Since the N63TU has two separate cooling systems, does draining the coolant from the bottom radiator hose drain both systems?
Also, I read the system takes 12.3 qts of coolant. Is this referring to both systems total? How much would the charge air cooling and engine/turbo cooling take each?
