Draining the Cooling System
Whenever repairs are to be made which would require disconnection of
coolant hoses, etc., the cooling system should be drained. Carefully remove
the filler cap and remove all pipe plugs.
Refilling the Cooling System
Close all drain cocks and fill with the proper coolant mixture. Run engine
with the pressure cap removed until operating temperature is reached and
the thermostat opens. Recheck level and add coolant if required. Run the
engine long enough to be sure the system is free of air and has the correct
amount of coolant.
