Cooling System Filling

STANDARD PROCEDURE-COOLING SYSTEM REFILLING
1. Tighten the radiator draincock and the cylinder block drain plug(s).
2. Fill system using a 50/50 mixture of water and antifreeze. Fill the radiator to the top and install the radiator cap. Add sufficient coolant to the reserve/ overflow tank to raise the level to the FULL mark.
3. Operate the engine with both the radiator cap and reserve/overflow tank cap in place. After the engine has reached the normal operating temperature, shut the engine off and allow it to cool.
4. Add coolant to the reserve/overflow tank as necessary. Only add coolant when the engine is cold. Coolant level in a warm engine will be higher due to thermal expansion.
