Coolant: Service and Repair
Replacement1. Turn the ignition switch ON (II). Set the climate control system to 90°F (32°C) or heater controls to full hot, then turn the ignition switch OFF. 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. Install a rubber hose (A) on the drain bolt (B) located at the rear of the cylinder block, then loosen the drain bolt.
5. When the coolant stops draining, tighten the drain bolt.
6. Tighten the radiator drain plug securely.
7. Remove, drain, and reinstall the coolant reservoir.
8. Pour Honda All Season Antifreeze/Coolant Type 2 into the radiator up to the base of the filler neck.
NOTE:
- Always use Honda All Season Antifreeze/Coolant Type 2. Using a non-Honda coolant can result in corrosion, causing the cooling system to malfunction or fail.
- Honda All Season Antifreeze/Coolant Type 2 is a mixture of 50% antifreeze and 50% water. Premixing is not required.

9. Start the engine. Hold the engine speed at 1,500 rpm until it warms up (the radiator fan comes on at least twice). Make sure the thermostat is open.
10. Turn off the engine. Check the level in the radiator, and add Honda All Season Antifreeze/Coolant Type 2, if needed.
11. Set the climate control or heater control panel to maximum cool. Start the engine. Hold the engine speed at 1,500 rpm for 5 minutes, then turn off the engine.
12. Check the level in the radiator, and add Honda All Season Antifreeze/Coolant Type 2, if needed.
13. Set the climate control or heater control panel to maximum heat. Start the engine. Hold the engine speed at 1,500 rpm for 5 minutes, then turn off the engine.
14. Check the level in the radiator, and add Honda All Season Antifreeze/Coolant Type 2, if needed.
15. Set the climate control or heater control panel to maximum cool. Start the engine. Hold the engine speed at 1,500 rpm for 3 minutes, then turn off the engine.
16. Check the level in the radiator, and add Honda All Season Antifreeze/Coolant Type 2, if needed.
17. Set the climate control or heater control panel to maximum heat. Start the engine. Hold the engine speed at 1,500 rpm for 3 minutes, then turn off the engine.
18. Check the level in the radiator, and add Honda All Season Antifreeze/Coolant Type 2, if needed.
19. Repeat steps 15 through 18 until the coolant level does not change in the radiator, then install the radiator cap loosely.
20. Set the climate control or heater control panel to maximum cool. Start the engine. Hold the engine speed at 2,500 rpm for 1 minute.
21. Set the climate control or heater control panel to maximum heat, and select high speed heat mode on the rear control panel. Measure the temperature of the air from the rear floor vent for 2 or 3 minutes. Make sure the temperature is above the standard line of the graph shown. If the temperature is below the standard line, repeat steps 15 through 18 several more times. Then loosely install the radiator cap and recheck.
22. Make sure you do not hear the sound of water flowing near the rear heater unit. If you hear water flowing, repeat steps 15through 18 several more times. Then loosely install the radiator cap and recheck.
23. Fill the reserve tank with Honda All Season Antifreeze/Coolant Type 2 up to the MAX mark on the tank, then add an extra 0.4 L (0.4 US qt.) coolant.
