Coolant
Your CRF’s liquid cooling system dissipates
engine heat through the coolant jacket that
surrounds the cylinder and cylinder head.
Maintaining the coolant will allow the cooling
system to work properly and prevent freezing,
overheating, and corrosion.
Coolant Recommendation
Use Pro Honda HP Coolant or an equivalent high
quality ethylene glycol antifreeze containing
corrosion protection inhibitors specifically
recommended for use in aluminum engines.
Check the antifreeze container label.
Use only distilled water as a part of the coolant
solution. Water that is high in mineral content or
salt may be harmful to the aluminum engine.
NOTICE
Using coolant with silicate inhibitors may cause
premature wear of water seals or blockage of
radiator passages. Using tap water may cause
engine damage.
The factory provides a 50/50 solution of
antifreeze and water in this motorcycle. This
coolant solution is recommended for most
operating temperatures and provides good
corrosion protection.
Decreasing the concentration of antifreeze to
less than 40% will not provide proper corrosion
protection.
Increasing the concentration of antifreeze is
not recommended because it decreases cooling
system performance. Higher concentrations of
antifreeze (up to 60%) should only be used to
provide additional protection against freezing.
Check the cooling system frequently during
freezing weather.
Checking & Adding Coolant
Refer to Safety Precautions on page 25.
1. With the engine at normal operating
temperature, check the coolant level in
the reserve tank. It should be between the
UPPER (1) and LOWER (2) level marks.
If the reserve tank (3) is empty, or if coolant
loss is excessive, check for leaks and see your
dealer for repair.
