CAUTION:ECB00401
If 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.
NOTE:
The radiator fan is automatically switched on or
off according to the coolant temperature in the
radiator.
If the engine overheats, see page 8-64 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.)

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.12. 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-
gine.

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.15. Remove panel E. (See page 8-8.)
16. Loosen the clamp screw, and then remove the
V-belt cooling duct.
17. Loosen the cylinder head air bleed bolt, with-
out removing it, to allow all of the air to escape
from the air bleed bolt hole.1. Water pump air bleed bolt

hole, tighten the cylinder head air bleed bolt to
the specified torque.
19. Start the engine and let it idle for ten minutes.
20. Rev the engine five times.
21. Pour the recommended coolant into the radia-
tor until it is full.22. 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.
NOTE:If 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.EBU27801Cleaning the air filter element The air filter element should be cleaned at the in-
tervals specified in the periodic maintenance and
lubrication chart. Clean the air filter element more
frequently if you are riding in unusually wet or dusty
areas.NOTE:There 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 removing

8Engine overheating
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.NOTE:If 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 NOTE.)
Start the engine. If the engine overheats again, have a
Yamaha dealer check and repair the cooling system.
There is
leakage.
