Coolant
48
Servicing Your Honda
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.
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.
NOTICE
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
Honda dealer for repair.

2. Open the air cleaner housing cover (4) by
turning the quick fastener (5)
counterclockwise and remove the left side
cover bolt (6), collar (7), seat mounting bolt
(8) and left side cover (9).

3. Remove the reserve tank cap (10).
Always add coolant to the reserve tank.
Do not attempt to add coolant by removing
the radiator cap.
