TIPDo not exceed the specified differential gear oil
quantity when filling. Overfilling will cause the oil
to seep out of the breather hose during and af-
ter riding.
 The differential gear case capacity is greater
than the recommended oil quantity, therefore
the oil level cannot be accurately checked from
the oil filler hole. 6. Check the oil filler bolt gasket for damage,
and replace it if necessary.
7. Install the oil filler bolt and its gasket, and then tighten the bolt to the specified torque.
8. Check the differential gear case for oil leak- age. If oil is leaking, check for the cause.
EBU23471CoolantThe 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.EBU27129To 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.
Recommended differential gear oil:See page 10-1.
Oil quantity: 0.35 L (0.37 US qt, 0.31 Imp.qt)
Tightening torque: Differential gear oil filler bolt:23 N·m (2.3 kgf·m, 17 lb·ft)

83. If the coolant is at or below the minimum level
mark, remove panel C to access the coolant
reservoir. (See page 8-8.)
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,
replace it with coolant as soon as possible,
otherwise the cooling system will not be 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.

TIPThe radiator fan is automatically switched on or
off according to the coolant temperature in the
radiator.
 If the engine overheats, see page 8-65 for fur-
ther instructions. EBU37130To change the coolant
WARNING
EWB01891Wait 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 the front carrier and panel F. (See
page 8-8.)
3. Remove the radiator cap. 4. Remove panels D and E. (See page 8-8.)
5. 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 footrest.)

86. Remove the coolant reservoir cap. 7. Disconnect the coolant reservoir hose on the
coolant reservoir side, and then drain the
coolant from the coolant reservoir.
8. After draining the coolant, thoroughly flush the cooling system with clean tap water.
9. Install the coolant drain bolt and its new gas- ket, and then tighten the bolt to the specified
torque.

11. Pour the recommended coolant into the res-
ervoir to the maximum level mark, and then
install the reservoir cap. NOTICE: Mix anti-
freeze with distilled water only. However, 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.
[ECB00992]
12. Pour the recommended coolant into the radi- ator until it is full.
13. Install the radiator cap, start the engine, let it idle for several minutes, and then turn it off. 14. Remove the radiator cap to check the coolant
level in the radiator. If it is low, add sufficient
coolant until it reaches the top of the radiator,
and then install the radiator cap.
15. Start the engine, and then check for coolant leakage.
TIPIf any leakage is found, have a Yamaha dealer
check the cooling system. 16. Install the panels and the front carrier.EBU37112Cleaning the air filterThe main air filter element and sub air filter ele-
ment should be cleaned every 20–40 hours of en-
gine operation. When servicing the air filter
elements, check the air filter case inlet for obstruc-
tions. Check the air filter case rubber joint to the
throttle body and the rubber joint manifold fittings
for an air-tight seal. Tighten all fittings securely to
avoid the possibility of unfiltered air entering the
engine.TIPReplace the air filter elements if damaged.

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. TIPIf coolant is not available, tap water can be temporarily used instead, provided that it is changed to the
recommended coolant as soon as possible. Wait until the
engine has cooled.
