DRAIN & REFILL

CAUTION
Do not remove a radiator cap while the engine and radiator are still hot. Danger of burns by scalding fluid and steam under pressure may result!

1. Make sure the vehicle is parked on a level surface.
2. Remove the coolant recovery reservoir fill cap.
3. With a cool engine, slowly rotate the radiator cap counterclockwise to the detent without pressing down on the cap.
4. Wait until any remaining pressure is relieved by listening for a hissing sound.
5. After all the pressure is relieved, press down on the cap and continue to rotate the radiator cap counterclockwise.

   Fig. 1: NEVER remove the radiator cap when the engine is hot!

6. With a suitable container to catch the fluid under the radiator, open the radiator drain cock.

   Fig. 2: The radiator drain cock is located at the bottom corner of the radiator

7. If equipped, remove the engine block drain plugs. This will help to drain the coolant from the block.

   Fig. 3: If equipped, remove the engine block drain plugs and let the coolant drain into a suitable container

8. Loosen or slide the recovery tank hose clamp at the radiator filler neck overflow tube and remove the hose. Holding the hose down to the drain pan, allow the recovery tank to empty. Attach the hose to the filler neck overflow and tighten the clamp.
9. Close the radiator drain cock and install the engine block drain plug.
10. Add enough coolant mixture to fill the system to a level just below the radiator neck. Fill the reservoir assembly to the FULL mark.

    NOTE: Fill the cooling system with a 50/50 mixture of water and Ethylene Glycol antifreeze.

11. Firmly set the parking brake. Run the engine with the radiator cap OFF, until normal operating temperature is reached.

    CAUTION
    Under some conditions, ethylene glycol is flammable. To avoid being burned when adding engine coolant, do not spill it on the exhaust system or on hot engine parts.

12. With the engine idling, add engine coolant to the radiator until the level reaches the bottom of the radiator fill neck. Install the cap assembly.

    Fig. 5: Cooling systems should be pressure tested for leaks periodically

    Fig. 6: Be sure the rubber gasket on the radiator cap has a tight seal

    Fig. 7: Periodically remove all debris from the radiator fins

    NOTE: Never add cold water to an overheated engine.

13. Add coolant to the recovery tank, as necessary.
14. After filling the radiator and recovery tank, run the engine until it reaches normal operating temperature, to make sure that the thermostat has opened and all the air is bled from the system.
