Engine CoolantThis coolant is premixed with 50% antifreeze 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.Check the amount of coolant in the reserve
tank.
2. 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: Honda Long Life Antifreeze/Coolant Type 2■
Reserve Tank
1Engine CoolantNOTICEIf temperatures consistently below −22°F (−30°C) are
expected, the coolant mixture should be changed to
a higher concentration. Consult a dealer for more
information.
If Honda antifreeze/coolant is not available, you may
use another major brand 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.

1. Make sure the engine and radiator are
cool.
2. Turn the radiator cap counterclockwise to
relieve any pressure in the cooling system.
Do not push the cap down when turning.
3. Push down and turn the radiator cap
counterclockwise to remove it.
4. The coolant level should be up to the base
of the filler neck. Add coolant if it is low.
5. Put the radiator cap back on, and tighten it
fully.
6. Pour coolant into the reserve tank until it
reaches the MAX mark. Put the cap back
on the reserve tank.

u If the coolant level in the reserve tank is
low, add coolant until it reaches the
MAX mark.
u If there is no coolant in the reserve tank,
