EBU34213To 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. Park the ATV on a level surface.
2. Remove panels A, B, C, and D. (See page8-9.)
3. Remove the footboard by removing the bolts and nuts. 4. Remove the radiator cap.

6. Place a container under the coolant reservoir
to collect the used coolant.
7. Remove the coolant reservoir cap.
8. Disconnect the coolant reservoir hose on the coolant reservoir side, and then drain the
coolant from the coolant reservoir.
9. After draining the coolant, thoroughly flush the cooling system with clean tap water.
10. Install the coolant drain bolt and its new gas- ket, and then tighten the bolt to the specified
torque. 11. Connect the coolant reservoir hose.
12. Pour the recommended coolant into the radi-
ator until it is full.
13. Pour the recommended coolant into the res- ervoir to the maximum level mark, and then
install the reservoir cap.
14. Loosen the water pump air bleed bolt, with- out removing it, to allow all of the air to es-
cape from the air bleed bolt hole.

815. When coolant begins to flow out of the bolt
hole, tighten the water pump air bleed bolt to
the specified torque.
16. Remove panel E. (See page 8-9.)
17. Loosen the clamp screw, and then remove the V-belt cooling duct. 18. Loosen the cylinder head air bleed bolt, with-
out removing it, to allow all of the air to es-
cape from the air bleed bolt hole.
19. When coolant begins to flow out of the bolt hole, tighten the cylinder head air bleed bolt
to the specified torque.
20. Start the engine and let it idle for ten minutes.
21. Rev the engine five times.

22. Pour additional coolant into the radiator until
it is full.
23. Stop the engine and allow it to cool. If the coolant level has dropped after the engine
has cooled, add sufficient coolant until it
reaches the top of the radiator, and then in-
stall the radiator cap.
24. Start the engine, and then check for coolant leakage.
TIPIf any leakage is found, have a Yamaha dealer
check the cooling system. 25. Install the V-belt cooling duct, and then tight-en the clamp screw.
26. Install the footboard by installing the bolts and nuts, and then tighten them to the speci-
fied torques.
TIPTighten footboard bolts B in the order shown. 1. Footboard nut
2. Footboard bolt A
3. Footboard bolt B

EBU34233Cleaning the air filter elementThe air filter element should be cleaned at the in-
tervals specified in the periodic maintenance and
lubrication chart. Clean or replace the air filter ele-
ment more frequently if you ride 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. 1. Park the ATV on a level surface.
Tightening torques:
Footboard nut:4.0 N·m (0.40 kgf·m, 3.0 lb·ft)

86. Wash the sponge material gently but thor-
oughly in solvent. WARNING! Always use
parts cleaning solvent. Never use low-
flash-point solvents or gasoline because
the engine could catch fire or explode.

7. Squeeze the excess solvent out of the sponge material and let it dry. NOTICE: Do
not twist the sponge material when
squeezing it.
[ECB00442]
8. Check the sponge material and replace it if damaged.
9. Apply Yamaha foam air filter oil or other qual- ity foam air filter oil to the sponge material.TIPThe sponge material should be wet but not drip-
ping. 10. Pull the sponge material over the air filter ele- ment frame, and then install the lock plate.
11. Insert the air filter element into the air filter case, and then install the air filter case cover
by hooking the holders onto the air filter case.
NOTICE: Make sure that the air filter ele-
ment is properly seated in the air filter
