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.
A102D001
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 sys-
tem 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 in-
side 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 antifreeze, but
not more than 60 percent antifreeze for cold weather
operation.
14. Fill the surge tank to the specified MAX fill mark on
the outside of the tank.
