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 max-
imum 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 8-53–8-63 for details.)CAUTION:_ Hard water or salt water is harmful to the en-
gine. You may use soft water if you cannot get
distilled water. _
Coolant reservoir capacity
(up to the maximum level mark):
0.25 L

Cooling system
1. Place the ATV on a level surface.
2. Check the coolant level in the coolant reser-
voir when the engine is cold as the coolant
level will vary with engine temperature.NOTE:_ The coolant level should be between the minimum
and maximum level marks. _3. If the coolant is at or below the minimum level
mark, remove panel D. (See pages 8-17–
8-19 for panel removal and installation proce-
dures.)
4. Remove the reservoir cap, add coolant to the
maximum level mark, install the reservoir
cap, and then install the panel.
