Cooling System: Service and Repair
Coolant Replacement1. Set the heater temperature control dial to maximum heat. 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 reservoir. Fill the tank halfway to the MAX mark with water, then up to the MAX mark with antifreeze.
8. Mix the recommended antifreeze with an equal amount of water in a clean container.
NOTE:
- Always use Genuine Honda Antifreeze/Coolant. Using a non-Honda coolant can result in corrosion, causing the cooling system to malfunction or fail.
- For best corrosion protection, the coolant concentration must be maintained year-round at 50% minimum. Coolant concentrations less than 50% may not provide sufficient protection against corrosion or freezing. Coolant concentrations greater than 60% will impair cooling efficiency and are not recommended.
- Do not use additional rust inhibitors or anti-rust products; they may not be compatible with the coolant.
Engine Coolant Refill Capacity (including the reservoir capacity of [0.6 Litre.. (0.6 US quart., 0.5 Imp quart.)]):
5.6 Litre. (5.9 US quart., 4.9 Imp quart.)
9. Pour coolant into the radiator up to the base of the filler neck, and 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 coolant if needed.
12. Put the radiator cap on tightly, then run the engine again and check for leaks.
