EBU19540Fuel Make sure that there is sufficient fuel in the tank.
(See page 4-16.)
WARNING
EWB00520Do not overfill the fuel tank. Fuel expands
when it heats up. If the fuel tank is overfilled,
fuel could spill out due to heat from the en-
gine or the sun.Be careful not to spill fuel, especially on the
engine or exhaust pipe which can cause a
fire and severe injury. Wipe up any spilled
fuel immediately.Do not refuel right after the engine has been
running and is still very hot.Be sure the fuel tank cap is closed securely.EBU19560Engine oil Make sure that the engine oil is at the specified lev-
el. Add oil as necessary. (See page 8-22.)EBU19590Final gear oil Make sure that the final gear oil is at the specified
level. Add oil as necessary. (See page 8-26.)
EBU19600Differential gear oil Make sure that the differential gear oil is at the
specified level. Add oil as necessary. (See page
8-29.)EBU19630Coolant Make sure that the coolant is at the specified level.
Add coolant as necessary. (See page 8-31.)TIPThe coolant level must be checked on a cold en-
gine since the level varies with engine tempera-ture.
WARNING
EWB00510Wait 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 pressureto escape before completely removing the cap.

ant or distilled water to the maximum level
mark, install the reservoir cap, and then install
the panel.
NOTICEECB00401If coolant is not available, use distilled water
or soft tap water instead. Do not use hard wa-
ter or salt water since it is harmful to the en-
gine.If water has been used instead of coolant, re-
place it with coolant as soon as possible,
otherwise 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, oth-
erwise the effectiveness of the coolant willbe reduced.TIPThe radiator fan is automatically switched on or
off according to the coolant temperature in the
radiator.If the engine overheats, see page 8-66 for fur-ther instructions.

EBU27761To 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 pressureto escape before completely removing the cap.
1. Place the ATV on a level surface.
2. Remove panels D and F. (See page 8-8.)
3. Place a container under the engine, and then
remove the coolant drain bolt. (Use a trough
or a similar object as shown to prevent coolant
from spilling on the engine guard.)
4. Remove panel B. (See page 8-8.)
5. Remove the radiator cap.

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

812. Pour the recommended coolant into the reser-
voir to the maximum level mark, and then in-
stall the reservoir cap.

ter or salt water since it is harmful to the en-

If water has been added to the coolant, have
a Yamaha dealer check the antifreeze con-
tent of the coolant as soon as possible, oth-
erwise the effectiveness of the coolant willbe reduced.
13. Loosen the water pump air bleed bolt, without
removing it, to allow all of the air to escape
from the air bleed bolt hole.
14. When coolant begins to flow out of the bolt
hole, tighten the water pump air bleed bolt to
the specified torque. Antifreeze/water mixture ratio:
1:1
Recommended antifreeze:
High-quality ethylene glycol antifreeze con-
taining corrosion inhibitors for aluminum en-
gines

822. 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.
23. Start the engine, and then check for coolant
leakage.
TIPIf any leakage is found, have a Yamaha dealercheck the cooling system.
24. Install the V-belt cooling duct, and then tighten
the clamp screw.
25. Install the panels.EBU27804Cleaning 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 are two check hoses at the bottom of the air
filter case, which are located behind panels D and
E. (See page 8-8 for an explanation on removingthe panels.) Check the hoses periodically and, if
dust or water collects in them, empty them and
clean the air filter element and air filter case.1. Air filter case check hose

WARNING
EWB02290Wait 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 rec-ommended 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.
There is
