14. Remove the engine oil tank filler cap, and then
gradually fill the oil tank with the remaining oil
quantity while regularly checking the oil level
on the dipstick.
15. Install and tighten the engine oil tank filler cap.
TIPBe sure to wipe off spilled oil on any parts after the
engine and exhaust system have cooled down.NOTICEECB00300●In order to prevent clutch slippage (since the
engine oil also lubricates the clutch), do not
mix any chemical additives. Do not use oils
with a diesel specification of “CD” or oils of a higher quality than specified. In addition,
do not use oils labeled “ENERGY CONSERV-
ING II” or higher.
●Make sure that no foreign material enters the
crankcase.16. Start the engine, and then let it idle for several
minutes while checking it for oil leakage. If oil
is leaking, immediately turn the engine off and
check for the cause.
17. Turn the engine off, and then check the oil lev- el and correct it if necessary.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.EBU27942To check the coolant level1. Place the ATV on a level surface.
Recommended oil:
See page 10-1.
Oil quantity: Without oil filter element replacement:1.75 L (1.85 US qt, 1.54 Imp.qt)
With oil filter element replacement: 1.85 L (1.96 US qt, 1.63 Imp.qt)

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 the coolant reservoir cap, add
coolant or distilled water to the maximum level
mark, and then install the reservoir cap.
NOTICE: If coolant is not available, use
distilled water or soft tap water instead. Do
not use hard water or salt water since they
are harmful to the engine. If water has
been used instead of coolant, replace it
with coolant as soon as possible, other-
wise the cooling system will not be pro-
tected 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.

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 A. (See page 8-10.)
3. Place a container under the engine, and thenremove the coolant drain bolt and its gasket.

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

9. Connect the coolant reservoir hose.
10. 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.

11. Pour the recommended coolant into the radia- tor until it is full.
12. Install the radiator cap, start the engine, let it idle for several minutes, and then turn it off. 13. 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.
14. Start the engine, and then check for coolant leakage.
TIPIf any leakage is found, have a Yamaha dealer
check the cooling system.15. Install the panel.EBU26806Cleaning the air filter element The air filter element should be cleaned at the in-
tervals specified in the periodic maintenance and
lubrication chart. Clean or, if necessary, replace
the air filter element more frequently if you are
riding in unusually wet or dusty areas.TIPThere is a check hose at the bottom of the air filter
case. If dust or water collects in this hose, empty
the hose and clean the air filter element and air fil-
ter case.
