Cooling System
Checking the Engine Coolant
Level
Check the level of the engine coolant
by looking at the expansion tank
mounted above the engine. If the
level is at or below the M I N line, add
coolant to bring it up to the MAX
line. This coolant should always be a
mixture of 50% antifreeze and 50%
water. Never add straight antifreeze
or plain water.
Always use Genuine Honda
Antifreeze/Coolant. The cooling
system contains many aluminum
components which can corrode if an
improper antifreeze is used. Some
antifreezes, even though labeled as
safe for aluminum parts, may not
provide adequate protection.
Adding Engine Coolant
EXPANSION TANK
CAP
Loosen the expansion tank cap by
turning it counterclockwise, without
pushing it down, until it stops. This
will relieve any remaining pressure in
the cooling system. Then remove the
cap by pushing down and turning.
Fill the expansion tank with coolant
to the MAX line and put the cap back
on.
Maintenance
MAX
M I N
Removing the expansion tank
cap while the engine is hot can
cause the coolant to spray out,
seriously scalding you.
Always let the engine and
radiator cool down before
removing the expansion tank cap.
