Coolant
Refer to Important Safety Precautions on page 31.
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.
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 the mechanical seal or
blockage of the 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.
Refer to Important Safety Precautions on page 31.
1. With the engine at normal operating
temperature, check the coolant level in the
reserve tank (1) from the inspection window
(2). It should be between the UPPER level (3)
and LOWER level (4) marks.
If the reserve tank is empty, or if coolant loss is
excessive, check for leaks and see your dealer
for repair.
2. Remove the reserve tank cap (5). Always add
coolant to the reserve tank. Do not attempt to
add coolant by removing the radiator cap.
3. Add coolant to the reserve tank as require to
bring the coolant level to the UPPER level
mark.
4. Install the reserve tank cap.
