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 8-57–8-67 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 8-19–
8-21 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.

CAUTION:_ Hard water or salt water is harmful to the en-
gine. You may use soft water if you cannot get
distilled water. _NOTE:_

If water is added, have a Yamaha dealer
check the antifreeze content of the coolant as
soon as possible.


The 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 8-142 for details. Coolant reservoir capacity
(up to the maximum level mark):
0.25 L

5. Remove the radiator cap.
6. Remove panel D. (See pages 8-19–8-21 for
panel removal and installation procedures.)
7. Remove the coolant reservoir cap.
8. Disconnect the hose on the coolant reservoir
side, and then drain the coolant from the
coolant reservoir.
9. After draining the coolant, thoroughly flush
the cooling system with clean tap water.
10. Replace the coolant drain bolt washer if it is
damaged, install the coolant drain bolt, and
then tighten it to the specified torque.
11. Connect the coolant reservoir hose.
12. Pour the recommended coolant into the res-
ervoir to the maximum level mark, and then
install the reservoir cap and panel D.
13. Pour the recommended coolant into the radi-
ator until it is full, and then install the radiator
cap. Tightening torque:
Coolant drain bolt:
10 Nm (1.0 m·kgf)

CAUTION:_ Hard water or salt water is harmful to the en-
gine. You may use soft water if you cannot get
distilled water. _14. Start the engine and let it idle for several min-
utes. Stop the engine, and then check the
coolant level in the radiator. If it is low, add
more coolant until it reaches the top of the ra-
diator.
15. Check for coolant leakage.Recommended antifreeze:
High quality ethylene glycol antifreeze
containing corrosion inhibitors for
aluminum engines.
Antifreeze and water mixing ratio:
1:1
Total amount:
1.30 L

Engine overheatingNOTE:If it is difficult to get the recommended coolant, tap water can be temporarily used, provided that it is
changed to the recommended coolant as soon as possible.
WARNING
Wait for the engine and radiator to cool before removing the radiator cap. You could be burned by
hot fluid and steam blown out under pressure. Always put a thick rag over the cap when opening.
Allow any remaining pressure to escape before completely removing the cap. Wait until the
engine has cooled.
Check the coolant level in the
coolant reservoir and/or radiator.
Level is OK.Level is low, check the
cooling system for leakage.
No
leakage.Leakage.
Ask a Yamaha dealer to inspect
and repair the cooling system.Add coolant. (See NOTE.)
Restart the engine. If the engine overheats again, ask a
Yamaha dealer to inspect and/or repair the cooling system.
