Cooling System: Service and Repair

CLEANING

Drain the cooling system and refill with clean water.

Run the engine with the radiator cap installed until the upper radiator hose is hot. Stop the engine, and drain the water from system. If the water is dirty, refill, run, and drain the system again, until the water runs clear. After flushing, refill the cooling system with a 50/50 mixture of the recommended antifreeze/coolant and distilled water.

INSPECTION
After performing a cleaning/flush procedure, carefully inspect all hoses, clamps and connections for deterioration and leaks. Inspect the radiator and heater core for leaks.
