Flushing the Cooling System 1. Drain the cooling system. 2. Close the radiator drain valve, leaving the drain hose in place. 3. Add one can of radiator flush to the radiator and fill the radiator with clean water. 4. Install the radiator cap, start the engine, and run until the engine reaches operating temperature (71-82° C / 160-180° F). 5. Shut off the engine and remove the ignition key. WARNING Hot coolant can cause severe burns. Allow the tem- perature of the radiator to drop from hot to warm before draining the coolant. 6. Carefully drain the cooling system while the cool- ant is still warm. 7. Allow the engine and radiator to cool completely. ATTENTION Adding cold water to a hot engine can cause engine damage. Allow the engine and radiator to cool com- pletely before adding water. 8. Add clean water to the radiator and allow the water to run through the system. Add more water as needed, until the water flowing from the drain valve is clear and free of sediment. 9. After the water has drained completely, close the drain valve and remove the drain hose. 10. Slowly add the new coolant mixture to the radia- tor until the level reaches the bottom of the fill neck. NOTE: residual water may be present in the radiator and the engine block. Adjust the coolant mixture to achieve a 50/50 ratio of coolant to water. 11. Install the radiator cap, start the engine, and run until the engine reaches operating temperature (71-82° C / 160-180° F). 12. Shut off the engine and allow the engine to cool. 13. Recheck the coolant level when the engine is cold. Add additional coolant if needed. 14. Install the right engine cover.
