Coolant: Service and Repair
DRAINING AND REFILLING THE COOLING SYSTEM
Caution: To avoid 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 cock.
Caution: 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 "Surge Tank" in this section.
6. Plug the drain cock.
7. Add the 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. You can tell 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: To avoid damaging the vehicle, never use an antifreeze mixture more concentrated than 60 percent antifreeze to 40 percent water. The
solution freezing point increases above this concentration.
13. Fill the cooling system through the surge tank with a mixture of ethylene glycol antifreeze and water. The mixture must be at least 50 percent
