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.

Differential gear oil
Make sure the differential gear oil is at the speci-
fied level. Add oil as necessary. (See pages 8-45–
8-49 for details.)
EBU01244
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 upper and lower
level marks on the coolant reservoir. If the coolant
level is at or below the lower level mark, add tap
water (soft water) to bring the level up to the upper
level mark. Change the coolant every two years.
(See pages 8-51–8-61 for details.) Recommended oil:
SAE 80 API “GL-4” Hypoid gear oil

Cooling system
1. Check the coolant level in the reservoir when
the engine is cold as the coolant level will
vary with engine temperature. The coolant
level should be between the maximum and
minimum marks.
2. If the level is low, remove panel D. (See pag-
es 8-17–8-21 for panel removal and installa-
tion procedures.)

3. Remove the reservoir cap, and then add
coolant or distilled water to raise it to the
specified level.
4. Install the panel.CAUTION:_ Hard water or salt water is harmful to the en-
gine. You may use soft water if you can’t 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.
