Coolant temperature warning light “”
When the coolant temperature reaches a specified
level, this light comes on to warn that the coolant
temperature is too hot. If the light comes on during
operation, stop the engine as soon as it is safe to
do so and allow the engine to cool down for about
10 minutes.CAUTION:_
The engine may overheat if the ATV is
overloaded. If this happens, reduce the
load to specification.
After restarting, make sure that the light is
out. Continuous use while the light is on
may cause damage to the engine.

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

Changing the coolant
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. _1. Place the ATV on a level surface.
2. Remove panels E and F. (See pages 8-29–
8-31 for panel removal and installation proce-
dures.)
3. Place a container under the engine, and then
remove the coolant drain bolt. (Use a trough
or a similar object as shown to prevent cool-
ant from spilling on the footrest.)
4. Remove the front carrier and panel C. (See
pages 8-23–8-27 for panel removal and in-
stallation procedures.)

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.

ator until it is full, and then install the radiator
cap. Tightening torque:
