If the coolant level in the reserve
tank is at or below the MIN line, add
coolant to bring it up to between the
MIN and MAX lines. Inspect the
cooling system for leaks.
Always use Honda Long-life Anti-
freeze/Coolant Type 2. This coolant
is pre-mixed with 50 percent
antifreeze and 50 percent distilled
water. Never add straight antifreeze
or plain water.
If Honda antifreeze/coolant is not
available, you may use another
major-brand non-silicate coolant as a
temporary replacement. Make sure it
is a high-quality coolant
recommended for aluminum engines.
Continued use of any non-Honda
coolant can result in corrosion,
causing the cooling system to
malfunction or fail. Have the cooling
system flushed and refilled with
Honda antifreeze/coolant as soon as
possible.
