7. Fill with fresh coolant - Close all drain valves/plugs and
fill with a mixture of antifreeze, soft water, and coolant
conditioner as specified in the Fuels, Lubricants, and
Coolant section.
8. Check coolant level - Fill radiator to the top of the filler
neck. Run the engine until operating temperature is
reached. Let the engine cool (preferably overnight) and
recheck the coolant level. Coolant level with a cold
engine should be at the bottom of the filler neck. When
filling the cooling system it may require several
operating/cooling periods to stabilize the coolant level
in the system. Add make-up coolant to the radiator as
needed to bring the coolant level to the correct level.
