Coolant
Check the coolant level in the coolant reservoir
when the engine is cold. (The coolant level will
vary with engine temperature.) The coolant level
is satisfactory if it is between the minimum and
maximum level marks on the coolant reservoir. If
the coolant level is at or below the minimum
level mark, add distilled water to bring the level
up to the maximum level mark. Change the
coolant every two years. (See pages 8-43–8-53
for details.)
cC
Hard water or salt water is harmful to the
engine. You may use soft water if you cannot
get distilled water.
Coolant reservoir capacity
(up to the maximum level mark):
0.29 L

check the antifreeze content of the coolant as
soon as possible.
8The radiator fan operation is completely auto-
matic. It is switched on or off according to the
coolant temperature in the radiator.
If your ATV overheats, see page 8-150 for
