Coolant temperature warning light “ ”
When the coolant temperature reaches a speci-
fied 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.
The electrical circuit of the warning light can be
checked by turning the key to “ON”. If the warn-
ing light does not come on, and then go off,
have a Yamaha dealer check the electrical cir-
cuit.

8The engine may overheat if the ATV is
overloaded. If this happens, reduce the
load to specification.
8After restarting, make sure that the light is
out. Continuous use while the light is on
may cause damage to the engine.

8Always set the parking brake before start-
ing the engine. The ATV could start mov-
ing unexpectedly if the parking brake is
not applied. This could cause loss of con-
trol or a collision.
8Always be sure you have released the
parking brake before you begin to ride.
The brake could overheat if you ride the
ATV without releasing the parking brake.
You could lose braking performance
which could cause an accident. You could
also wear out the brakes prematurely.

Hard water or salt water is harmful to the
engine. You may use soft water if you can’t
get distilled water.
NOTE:
8If water is added, have a Yamaha dealer
check the antifreeze content of the coolant as
soon as possible.
8The 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 8-138 for
details.

Never operate the engine with the air filter
element removed. This will allow unfiltered
air to enter the engine, causing rapid engine
wear and possible engine damage.
Additionally, operation without the air filter
element will affect the fuel injection system
with subsequent poor performance and pos-
sible engine overheating.

Engine overheating
NOTE:
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.

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
reservoir tank 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.
