Radiator
Engine Coolant Refilling and Bleeding (cont'dl
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 corro-s\on, ca
sng t\e coo\
g sys\em \o ma\lunct\on
o. fail.
For best corrosion protection, the coolant con-
centration must be maintained year-round at50% minimum. Coolant concentrations less than
50% may not provide sufficient protection against
corrosion or freezing. Coolant concentrationsgreater than 60% will impair cooling efficiency
and are not recommended.
Do not use additional rust inhibitors or anti-rustproducts; they may not be compatible with the
coolant.

9. Pour coolant into the radiator uD to the base of the
filler neck. When pouring engine coolant. do not let
coolant spill on any electrical pans or the paint. lf
any coolant spills, rinse it oft immediately.
Start the engine, and let it run until it warms up (the
radiator fan comes on at least twice).
Turn off the engine. Check the level in the radiator,
add coolant if needed.
Put the radiator cap on tightly. then run the engine
again and check for leaks.
