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.
Antifreeze/water mixture ratio:
1:1

taining corrosion inhibitors for aluminum
engines

WARNING
EWB02341Do not start the engine when cleaning the
spark arrester, otherwise it could cause injury
to the eyes, burns, carbon monoxide poison-
ing, possibly leading to death, and start a fire.
Always let the exhaust system cool prior to
touching exhaust components. EBU23921V-belt cooling duct check hoseIf dust or water collects in the V-belt cooling duct
check hose, remove the hose and clean it.
EBU23932V-belt case drain plugAfter riding in water deep enough to allow it to en-
ter the V-belt case, remove the V-belt case drain
plug to drain the water from the case.TIPIf water drains from the V-belt case after removing
the plug, have a Yamaha dealer check the ATV as
the water may affect other engine parts.

WARNING
EWB02291Wait 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. 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.
Check the coolant level in the
reservoir and radiator.
The coolant level
is OK.The coolant level is low.
Check the cooling system
for leakage.
Have a Yamaha dealer check
and repair the cooling system.Add coolant. (See TIP.)
Start the engine. If the engine overheats again, have a
Yamaha dealer check and repair the cooling system.
