7. When the coolant stops draining, tighten the radiator drain plug, water pipe drain bolts and engine drain bolts.

-

Be sure to replace the water pipe drain bolt washers with new ones.

8. Open all four bleeders. 

1) Loosen the radiator bleed plug. 
2) Remove the heater pipe bleed bolt. 
3) Loosen the water pipe bleed bolt. 
4) Loosen the engine bleed bolt on the therms cover.

9. Mix the recommended antifreeze/coolant 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 concentrations 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.

CAUTION:
-

Do not mix different brands of antifreeze/coolant.

-

Do not use additional rust inhibitors or anti-rust products; they may not be compatible with the recommended coolant.

10. Fill the expansion tank with engine coolant. As coolant starts to run out in a steady stream without bubbles, tighten the bleeders in sequence:

thermo cover bleed bolt, radiator bleed plug, heater pipe bleed and water pipe bleed bolt.

11. After tightening all the bleeding bolts and plug, fill the expansion tank with coolant up to the MAX line.
