WARNING:
Do not remove cylinder block drain plugs or loosen radiator draincock with system hot and under pressure. Serious burns from coolant can occur.
Drain the cooling system and refill it with water. Run the engine with the radiator cap installed until the upper radiator hose is hot. Stop the engine and drain the water from the system. If the water is dirty, fill the system with water, run the engine and drain the system. Repeat until the water drains clean.
