Coolant: Service and Repair
Coolant Replacement1. 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 radiator are cool to the touch.
3. Loosen the drain plug (A), and drain the coolant.
4. After the coolant has drained, tighten the radiator drain plug securely.
5. Remove, drain, and reinstall the coolant reservoir.
6. Fill the coolant reservoir to the MAX mark (A) with Honda Long Life Antifreeze/Coolant Type 2 (P/N OL999-9011).
7. 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 (P/N OL999-9011). 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.
^ If the vehicle is regularly driven in very low temperatures (under -31°F, -35°C) a 60% concentration of coolant should be used. To accomplish this, pour 1.6 L (0.4 US gal) of Honda Coolant Concentrate (P/N OL999-9020) into the radiator first, then add Honda Long Life antifreeze/Coolant Type 2 until the radiator is full.
8. Loosely install the radiator cap.
9. Start the engine. Set the heater temperature control dial to maximum heat and let it run until it warms up (the radiator fan comes on at least twice).
10. Turn off the engine. Check the level in the radiator, and add Honda Long Life Antifreeze/Coolant Type 2, if needed.
11. Put the radiator cap on tightly, then start the engine again, and check for leaks.
12. Clean up any spilled engine coolant.
13. 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 11.
14. Connect the Honda Diagnostic System (HDS) to the data link connector (DLC).
15. 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.
16. Turn the ignition switch to ON (II).
17. Select BODY ELECTRICAL with the HDS.
18. Select ADJUSTMENT in the GAUGE MENU with the HDS.
19. Select RESET in the MAINTENANCE MINDER with the HDS.
20. Select MAINTENANCE SUB ITEM 5 RESET with the HDS.
