NOTE:

Use Honda Long Life Antifreeze/Coolant Type 2, and if necessary add Honda Extreme Cold Weather Antifreeze/Coolant Type 2 (concentrate). Using a non-Honda coolant can result in corrosion, causing the cooling system to malfunction or fail.

Honda Long Life Antifreeze/Coolant Type 2 is a mixture of 50 % antifreeze and 50 % water. Honda Extreme Cold Weather Antifreeze/Coolant Type 2 is a 100% concentration coolant. Do not add water to either coolant.

If the vehicle is regularly driven in very low temperatures (below -22 °F ( -30 °C)), a 60 % concentration of coolant should be used.
