COOLING SYSTEM
RADIATOR COOLANT
Release the retaining straps and open the front ,.
hood.
Check the coolant level of the reserve tank with the
engine running at normal operating temperature.
The level should be between the "MAX" and HMIN"
level lines with the vehicle upright on a level sur-
face.
If t he level is low, remove the reserve tank cap and
fill the tank up to the "MAX" level line with a 1;1
mixture of distilled water and antifreeze (coolant
preparation: page 7-5).
RECOMMENDED ANTIFREEZE:
Pro Honda HP coolant or an equivalent high qual -
ity
ethylene glvcol antifreeze containing silicate·
free corrosion inhibitors
NOTICE
Using coolant with silicate corrosion inhibitors may
cause premature wear
of
water pump seals or
blockage of radiator passages. Using tap warer may
cause engine damage.
Check to see if there are any coolant leaks when the
coolant level decreases very rapidly.
If the reserve tank becomes completely empty, there
is a possibility of air getting into the cooling system.
Be sure to remove any air from the cooling system
(page 7-6).
INSPECTION
Remove the following:
- engine front cover (page 3-6)
- center frame cover (page 3-7)
Release the retaining straps and open the front
hood.
Check for any coolant leakage f rom the water pump,
water hoses and hose joints.
Check the water hoses for cracks or deterioration
and replace if necessary.
Check that all hose clamps are tight.
Remove the front grille (page 3- 15).
Check the radiator air passage for dogs or damage.
Straighten bent fins with a small, flat blade screw-
driver and remove insects, mud or other obstruc-
tions with compressed air or low pressure water.
Replace the radiator if the air flow is restricted over
more than 20% of the radiating surface.
