EBU23546To 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 panel A. (See page 9-10.)
3. Place a container under the engine, and thenremove the coolant drain bolt and its gasket. 4. Remove the radiator cap.

95. Remove the coolant reservoir cap.
6. Disconnect the coolant reservoir hose on the
coolant reservoir side, and then drain the
coolant from the coolant reservoir.
7. After draining the coolant, thoroughly flush the cooling system with clean tap water.
8. Install the coolant drain bolt and its new gas- ket, and then tighten the bolt to the specified
torque. 9. Connect the coolant reservoir hose.
10. Pour the recommended coolant into the res- ervoir to the maximum level mark, and then
install the reservoir cap.
11. Pour the recommended coolant into the radi- ator until it is full, and then install the radiator
cap.
12. Start the engine, let it idle for several minutes, and then turn it off.
TIPWhile the engine is idling, check the cooling sys-
tem for leaks. 13. When the engine is cool, remove the radiatorcap to check the coolant level in the radiator.
If it is low, add sufficient coolant until it reach-
es the top of the radiator, and then install the
radiator cap.
14. Install the panel.EBU2680BCleaning the air filter elementThe air filter element should be cleaned at the in-
tervals specified in the periodic maintenance
chart. Clean or, if necessary, replace the air filter
element more frequently if you are riding in unusu-
ally wet or dusty areas.

Engine overheating
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.
