8. Check the differential gear case for oil leak-
age. If oil is leaking, check for the cause.
EBU23470Coolant The coolant level should be checked before each
ride. In addition, the coolant must be changed at
the intervals specified in the periodic maintenance
and lubrication chart.EBU27126To check the coolant level1. Place the ATV on a level surface.TIPThe coolant level must be checked on a cold en-
gine since the level varies with engine tempera-
ture.2. Check the coolant level in the coolant reser- voir.TIPThe coolant should be between the minimum and
maximum level marks.
3. If the coolant is at or below the minimum levelmark, remove panel D to access the coolant
reservoir. (See page 8-10.)
4. Remove the coolant reservoir cap, add cool- ant or distilled water to the maximum level
mark, install the reservoir cap, and then install
the panel. NOTICE: If coolant is not avail-
able, use distilled water or soft tap water
instead. Do not use hard water or salt wa-
ter since they are harmful to the engine. If
water has been used instead of coolant, re-
place it with coolant as soon as possible,
otherwise the cooling system will not be1. Maximum level mark

8protected 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.EBU27766To 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.

4. Place a container under the engine, and then
remove the coolant drain bolt and its gasket.
(Use a trough or a similar object as shown to
prevent coolant from spilling on the engine
guard.)

86. 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.

13. 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.

taining corrosion inhibitors for aluminum en-
gines

out removing it, to allow all of the air to escape
from the air bleed bolt hole. 19. When coolant begins to flow out of the bolt
hole, tighten the cylinder head air bleed bolt to
the specified torque.
20. Start the engine and let it idle for ten minutes.
21. Rev the engine five times.

23. 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.
