Caution: Before removing the expansion tank cap, wait until the engine has cooled down to prevent the release of hot coolant or steam.
1. Place a container under the vehicle to drain the coolant.
2. Remove the expansion tank cap.
3. Open the drain valve.
Caution: Store drained coolant in a container specifically designed for disposal of coolant. Never pour used coolant into the sewer. Antifreeze containing ethylene glycol is an extremely toxic chemical. Discharging it into the sewer or groundwater may cause environmental pollution.
Flushing the system
1. Place a container underneath to catch any leaking liquid.
2. Remove dirt and sediment from the inner surface of the expansion tank.
3. Close the drain valve.
4. Fill the expansion tank with clean water. Fill the tank slowly so that the top hose of the tank is above the surface of the water. This will release air from the system.
5. Start the engine.
6. Let the engine run until the thermostat opens. An open thermostat is indicated by the radiator hoses becoming hot.
7. Stop the engine.
8. Drain the water.
Continue flushing the system until the drained water is clear and free of antifreeze and rust particles.
Filling the system
Fill the cooling system through the expansion tank with a solution of ethylene glycol and water. The solution should contain at least 50% and no more than 60% ethylene glycol for operation in cold climates.
Note: Never use antifreeze containing more than 60% ethylene glycol and less than 40% water.
Add fluid to the expansion tank no higher than the MAX mark on the outer surface of the tank.
