2. Remove the bulkhead cover.
3. Remove the splash shield.
4. Remove the radiator cap.





5. Loosen the drain plug (A), and drain the engine coolant.





6. Remove the reserve tank mounting bolt (A), and remove the reserve tank.
7. Remove the engine coolant tube from the radiator. Put the end of the coolant tube lower than the reserve tank and drain the coolant in the tank.

10. Install the bulkhead cover.





11. Fill the reserve tank between the MIN mark (A) and the MAX mark (B) with Honda Long Life Antifreeze/Coolant Type 2 (P/N OL 999-9001).

NOTE:
- Always use Honda Long Life Antifreeze/Coolant Type 2 (P/N OL 999-9001). Using a non-Honda coolant can result in corrosion, causing the cooling system to malfunction or fail.
- Honda Long Life Antifreeze/Coolant Type 2 is a mixture of 50 % antifreeze and 50 % water. Do not add water.

13. Install the radiator cap loosely.
14. Start the engine, and let it run until it warms up (the radiator fan comes on at least twice).
15. Turn off the engine. Check the level in the radiator and add Honda Long Life Antifreeze/Coolant Type 2 if needed.
16. Put the radiator cap on tightly, then run the engine again and check for leaks.
