EBU30530Coolant temperature warning light “ ”
This warning light comes on when the engine over-
heats. When this occurs during operation, stop the
engine as soon as it is safe to do so and allow it to
cool down for about 10 minutes.
The electrical circuit of the warning light can be
checked by turning the key to “ ” (on). The warn-
ing light should come on for a few seconds, and
then go off.
If the warning light does not come on initially when
the key is turned to “ ” (on), or if the warning light
remains on, have a Yamaha dealer check the elec-
trical circuit.NOTICEECB00891●The engine may overheat if the ATV is over-
loaded. In this case, reduce the load to spec-
ification.●The engine may also overheat if mud or dirt
has accumulated on the radiator (i.e., after
riding in wet terrain). In this case, see page
8-20 for an explanation on how to access the
radiator.
●Start the engine after making sure that the
warning light is out. Continuous use while
the warning light is on may cause damage to
the engine.EBU30480Engine trouble warning light “ ”
This warning light comes on or flashes when an
electrical circuit monitoring the engine is not work-
ing correctly. When this occurs, have a Yamaha
dealer check the self-diagnosis system. (See page
4-7 for an explanation of the self-diagnosis device.)
The electrical circuit of the warning light can be
checked by turning the key to “ ” (on). The warn-
ing light should come on for a few seconds, and
then go off.
If the warning light does not come on initially when
the key is turned to “ ” (on), or if the warning light
remains on, have a Yamaha dealer check the elec-
trical circuit.EBU30570Electric Power Steering warning light “EPS”
(for EPS model)
This warning light comes on when the key is turned
to “ ” (on), and then goes off once the engine is
started. If the warning light remains on or comes on

EBU28671Removing the radiator grills The radiator grills can be removed to access the
radiator for cleaning.
To remove a radiator grill
Remove the quick fastener, pull the radiator grill
outward at the top, and then pull it upward.
To install a radiator grill
Place the radiator grill in its original position, and
then install the quick fastener.
EBU23213Checking the spark plug The spark plug is an important engine component,
which is easy to check. Since heat and deposits
will cause any spark plug to slowly erode, the spark
plug should be removed and checked in accor-
dance with the periodic maintenance and lubrica-
tion chart. In addition, the condition of the spark
plug can reveal the condition of the engine.
To remove the spark plug1. Remove the spark plug cap.

protected against frost and corrosion. If
water has been added to the coolant, have
a Yamaha dealer check the antifreeze con-
tent of the coolant as soon as possible,
otherwise the effectiveness of the coolant
will be reduced.
[ECB01011]
TIP●The radiator fan is automatically switched on or
off according to the coolant temperature in the
radiator.●If the engine overheats, see page 8-68 for fur-
ther instructions.EBU27767To change the coolant
WARNING
EWB01890Wait 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 place 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 panel D. (See page 8-10.)
3. Remove the footboard by removing the bolts
and nuts.

6. Remove the radiator cap.
7. Remove the coolant reservoir cap.
8. Disconnect the coolant reservoir hose on the
coolant reservoir side, and then drain the cool-
ant from the coolant reservoir. 9. After draining the coolant, thoroughly flush the
cooling system with clean tap water.
10. Install the coolant drain bolt and its new gas- ket, and then tighten the bolt to the specified
torque.
11. Connect the coolant reservoir hose.
12. Pour the recommended coolant into the radia- tor until it is full.

813. Pour the recommended coolant into the reser-
voir to the maximum level mark, and then in-
stall the reservoir cap. NOTICE: Mix
antifreeze with distilled water only. Howev-
er, if distilled water is not available, soft
water may be used for refilling. Do not use
hard water or salt water since they are
harmful to the engine.
[ECB00991]
14. Loosen the water pump air bleed bolt, without removing it, to allow all of the air to escape
from the air bleed bolt hole. 15. When coolant begins to flow out of the bolt
hole, tighten the water pump air bleed bolt to
the specified torque.
16. Remove panel E. (See page 8-10.)
17. Loosen the clamp screw, and then remove the V-belt cooling duct.
Antifreeze/water mixture ratio:
1:1
Recommended antifreeze: High-quality ethylene glycol antifreeze con-
taining corrosion inhibitors for aluminum en-
gines
Coolant quantity: Radiator capacity (including all routes):1.99 L (2.10 US qt, 1.75 Imp.qt)

823. Stop the engine and allow it to cool. If the cool-
ant level has dropped after the engine has
cooled, add sufficient coolant until it reaches
the top of the radiator, and then install the ra-
diator cap.
24. Start the engine, and then check for coolant leakage.
TIPIf any leakage is found, have a Yamaha dealer
check the cooling system.25. Install the V-belt cooling duct, and then tightenthe clamp screw.
26. Install the footboard by installing the bolts and nuts, and then tighten them to the specified
torques.
