Coolant: Service and Repair

Coolant Replacement

1. Start the engine. Set the heater temperature control dial to maximum heat, then turn off the ignition switch. Make sure the engine and radiator are cool to the touch.
2. Remove the radiator cap.
3. Loosen the drain plug (A) and drain the coolant.





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





5. After the coolant has drained, reinstall the drain bolt with a new washer.
6. Tighten the radiator drain plug securely.
7. Fill the coolant reservoir to the MAX mark (A) with Honda Long Life Antifreeze/Coolant Type 2.





8. Pour Honda Long Life Antifreeze/Coolant Type 2 into the radiator up to the base of the filler neck.

NOTE:
^ Always use Honda Long Life Antifreeze/Coolant Type 2. 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.





9. Install the radiator cap loosely.
10. Start the engine and let it run until it warms up (the radiator fan comes on at least twice).
11. Turn off the engine. Check the level in the radiator and add Honda Long Life Antifreeze/Coolant Type 2 if needed.

NOTE: Removing the radiator cap while the engine is hot can cause the coolant to spray out. Always let the engine and radiator cool before removing the cap.

12. Put the radiator cap on tightly, then run the engine again and check for leaks.
13. Clean up any spilled engine coolant.
14. If the maintenance minder required engine coolant replacement, reset the maintenance minder, and this procedure is complete. If the maintenance minder did not require engine coolant replacement, go to step 15.
15. Connect the Honda Diagnostic System (HDS) to the data link connector (DLC).
16. Make sure the HDS communicates with the vehicle and the engine control module (ECM)/powertrain control module (PCM). If it doesn't communicate, troubleshoot the DLC circuit.
17. Turn the ignition switch ON (II).
18. Select BODY ELECTRICAL with the HDS.
19. Select ADJUSTMENT in the GAUGE MENU with the HDS.
20. Select RESET in the MAINTENANCE MINDER with the HDS.
21. Select MAINTENANCE SUB ITEM 5 RESET with the HDS.
