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 page9-10.)

16. Remove panel E. (See page 9-10.)
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.

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.

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. TIP
Tap water can be used in an emergency. Change to the recommended coolant as soon as possible.
 The engine will tend to overheat if the radiator is caked with mud, or if the ATV is overloaded. 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.
