Coolant: Service and Repair
Coolant Replacement1. Start the engine. Set the heater temperature control dial to maximum heat, then turn off the engine. 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 rear side of the cylinder block.
5. After the coolant has drained, apply liquid gasket 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 reservoir. Fill the reservoir 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 reservoir capacity of 0.6 liter (0.6 US quart. 0.5 Imp quart)]:
M/T: 5.5 liter (5.8 US quart, 4.8 Imp quart)
A/T: 5.4 liter (5.7 US quart, 4.8 Imp quart)
9. Loosen the air bleed bolt (A) in the thermostat housing, then pour coolant into the radiator to the bottom of the filler neck. Do not let coolant spill on any electrical parts or the paint. If any coolant spills, rinse it off immediately.
10. Tighten the bleed bolt as soon as coolant starts to run out in a steady stream.
11. 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 coolant to bring the level back up to the bottom of the filler neck.
12. Put the radiator cap on tightly, then run the engine again and check for leaks.
