Does motor have to be warmed first to open thermostat or bottom hose pulled for complete system drain/flush?
Manual says coolant capacity is 12 quarts.
I opened both radiator and block drain petcocks.
Drained and flushed system (didn"t quantify volume drained).
Added 1 gallon antifreeze and 1 gallon water.
Radiator is full.
Where does the other gallon of fresh water go?
