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.
To check the coolant temperature warning light,
shift the drive select lever into neutral, turn the key
to “ON”, and then press the start switch. If the light
does not come on, have a Yamaha dealer inspect
the electrical circuit.CAUTION:_

The engine may overheat if the ATV is
overloaded. If this happens, reduce the
load to specification.


Restart after making 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 8-45–8-55 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

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 8-126 for details. Coolant reservoir capacity
(up to the maximum level mark):
