Cooling System
This coolant is premixed with 50% an tifreeze and 50% water. Do not add any
straight antifreeze or water.
We recommend you check the engine coolant level every time you refuel. Check the
reserve tank first. If it is completely empty, also check the coolant level in the
radiator. Add the engine coolant accordingly.
1. Make sure the engine and radiator are cool.
2. Check the amount of cool ant in the reserve tank.
u If the coolant level is below the MIN
mark, add the specified coolant until it
reaches the MAX mark.
3. Inspect the cooling system for leaks.
Specified coolant: Ho nda Long Life Antifreeze/Coolant Type 2
■Reserve Tank
1Cooling System
NOTICE
Genuine Honda engine coolant is a 50/50 mixture of
antifreeze and water that can withstand freezing at
temperatures as low as about -31°F (-35°C). If your
vehicle is consistently subjected to temperatures below
this, the concentration of antifreeze in the coolant
should be increased. Consult a dealer for details.
If Honda antifreeze/coolant is not available, you may use
another major brand of non-silicate coolant as a
temporary replacement. Check that 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.
Do not add rust inhibitors or other additives to your
vehicle's cooling system. They may not be compatible
with the coolant or with the engine components.
3WARNING
Removing the radiator 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 radiator cap.

u If the cooling fan is not operating,
immediately turn the power system off.
2. Once the engine has cooled down, inspect
the coolant level and check the cooling
system components for leaks.
u If the coolant level in the engine coolant
reserve tank is low, add coolant until it
reaches the MAX mark.
u If there is no coolant in the engine
coolant reserve tank, check that the
radiator is cool. Cover the radiator cap
with a heavy cloth an d open the cap. If
necessary, add coolant up to the base of
