Coolant: Service and Repair
ON-VEHICLE SERVICE
Draining And Refilling The Cooling System
Caution: To prevent personal injury, do not remove the surge tank cap while the engine and the radiator are hot Scalding fluid and steam may be
blown out under pressure.
1. Place a pan below the vehicle to catch the draining coolant.
2. Remove the surge tank cap.
3. Unplug the drain plug.
Caution: To prevent personal injury and to protect the environment, dispose of the used coolant in a used coolant holding tank to be picked up
with the used oil for disposal. Never pour the used coolant down the drain. Ethylene glycol antifreeze is an extremely toxic chemical. Disposing of
it into the sewer system or the ground water can contaminate the local environment
4. Catch the escaping fluid in a drain pan.
5. Remove all sludge and dirt from inside the surge tank. Refer to Coolant Overflow Reservoir.
6. Screw in the drain plug.
7. Add clean water to the surge tank.
8. Fill the tank slowly so that the upper reservoir hose remains above the water line. This allows the air inside the cooling system to escape.
9. Start the engine.
10. Run the engine until the thermostat opens. The thermostat is open when both radiator hoses are hot to the touch.
11. Stop the engine.
12. Repeat steps 1 through 9 until the drained water is clear and free of coolant and rust.
Notice: Never use an antifreeze mixture more concentrated than 60 percent antifreeze to 40 percent water. The solution freezing point increases
above this concentration.
