Coolant: Service and Repair

Coolant Replacement

1. Wait until the engine is cool, then carefully remove the radiator cap.

2. Start the engine. Set the heater temperature control dial to maximum heat, then turn the ignition switch to LOCK (0). Make sure the engine and the radiator are cool to the touch.

3. Loosen the drain plug (A), and drain the coolant.






4. Remove the drain bolt (A) from the right side of the engine block.

5. After the coolant has drained, apply liquid gasket, P/N 08718-0009, to the drain bolt threads, then reinstall the bolt with a new washer and tighten it securely.

6. Tighten the radiator drain plug securely.

7. Remove, drain, and reinstall the coolant reservoir. Fill the coolant reservoir to the MAX mark with Honda Long Life Antifreeze/Coolant Type 2 (P/N OL999-9001).






8. Remove the bleed cap (A) from the heater bypass tube.






9. Loosen the air bleed bolt (A) in the intake manifold, then pour Honda Long Life Antifreeze/Coolant Type 2 into the radiator to the base of the filler neck. Do not let coolant spill on any electrical parts or the paint. If any coolant spills, rinse it off immediately.
NOTE:

- Always use Honda Long Life Antifreeze/Coolant Type 2 (P/N OL999-9001). 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. Premixing is not required.





10. Tighten the air bleed bolt as soon as coolant starts to run out in a steady stream.

11. Reinstall the bleed cap on the heater bypass tube as soon as coolant starts to run out in a steady stream.

12. With the radiator cap off, start the engine and let it run until warmed up (radiator fan comes on at least twice). Then, if necessary, add more Honda Long Life Antifreeze/Coolant Type 2 to bring the level back up to the base of the filler neck.

13. Put the radiator cap on securely, then run the engine again and check for leaks.

14. Clean up any spilled engine coolant.
