EVU00181
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. (See page 8-140.)CAUTION:_

The engine may overheat if the vehicle 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 additional coolant to bring the level up to
maximum level mark. If coolant is not available,
add distilled water. Change the coolant every two
years. (See pages 8-47–8-49 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):
0.35 L (0.31 Imp qt, 0.37 US qt)

Coolant
The coolant level should be checked before each
ride.
Checking the coolant level
1. Place the vehicle on a level surface.
2. Open the hood. (See pages 8-17–8-19 for
hood opening and closing procedures.)
3. Check the coolant level in the coolant reser-
voir when the engine is cold as the coolant
level varies with engine temperature.NOTE:_ The coolant should be between the minimum and
maximum level marks. _4. If the coolant is at or below the minimum level
mark, remove the reservoir cap, add coolant
to the maximum level mark, install the reser-
voir cap, and then close the hood.

CAUTION:_ Mix antifreeze with distilled water only. Howev-
er, if distilled water is not available, soft water
may be used for refilling._Changing the coolant
The coolant must be changed by a Yamaha dealer
at the intervals specified in the periodic mainte-
nance and lubrication chart.NOTE:_

Adding water instead of coolant lowers the an-
tifreeze content of the coolant. If water is used
instead of coolant, have a Yamaha dealer
check the antifreeze content of the coolant as
soon as possible.


The radiator fan is automatically switched on or
off according to the coolant temperature in the
radiator.
_If your vehicle overheats, see page 8-140 for de-
tails.
