cap, add coolant to the maximum level
mark, install the reservoir cap. Changing the coolant
WARNING
EWB01891Wait for the engine and
radiator to cool be-
fore 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 com-
pletely removing the cap. 1. Park the vehicle on a level surface.
2. Remove the hood. (See page 8-10 for hood removal and installation proce-
dures.)
3. Remove the right rear panel. (See page 8-11 for right rear panel removing and in-
stalling procedures.)
4. Place a container under the engine to col- lect the used coolant.
5. Remove the radiator cap.

9. Disconnect the coolant reservoir hose,and then drain the coolant from the cool-
ant reservoir.
10. After draining the coolant, thoroughly flush the cooling system with clean tap
water.
11. Install the coolant drain bolt and its new gasket and then tighten the bolt to the
specified torque. 12. Connect the coolant reservoir hose.
13. Pour the recommended coolant into the
radiator until it is full.
14. Pour the recommended coolant into the
reservoir to the maximum level mark, and
then install the reservoir cap.
NOTICEECB02190Mix antifreeze with distilled water only.
However, if distilled water is not available,
soft water may be used for refilling. Do not
use hard water or salt water since they are
harmful to the engine.

15. Loosen the water pump air bleed bolt,without removing it, to allow all of the air
to escape from the air bleed bolt hole. 16. When coolant begins to flow out of the
bolt hole, tighten the water pump air
bleed bolt to the specified torque.
17. Loosen the cylinder head air bleed bolt, without removing it, to allow all of the air
to escape from the air bleed bolt hole.Antifreeze/water mixture ratio:1:1

taining corrosion inhibitors for aluminum
engines

18. When coolant begins to flow out of thebolt hole, tighten the cylinder head air
bleed bolt to the specified torque.
19. Start the engine and let it idle for ten mi- nutes.
20. Rev the engine five times.
21. Pour additional coolant into the radiator until it is full. 22. Stop the engine and allow it to cool. If the
coolant level has dropped after the en-
gine has cooled, add sufficient coolant
until it reaches the top of the radiator, and
then install the radiator cap.
23. Check the coolant level in the reservoir. If necessary, remove the coolant reservoir
cap, add coolant to the maximum level
mark, and then install the cap.
24. Start the engine, and then check for cool- ant leakage.
TIPIf any leakage is found, have a Yamaha dealer
check the cooling system. 25. Install the panel and the hood.EBU32400Axle bootsCheck the axle boots for holes or tears.
If any damage is found, have them replaced
by a Yamaha dealer.

Engine overheating
Wait for the engine to cool before removing the radiator cap. WARNING! If the engine is not
cool when removing the radiator cap, hot fluid and steam could blow out under pressure
and burn you.
[EWB03460]
Place a thick rag over the cap and remove the cap slowly to allow any re-
maining pressure to escape.
TIPIf it is difficult to get the recommended coolant, tap water can be used temporarily, provided that
it is changed to the recommended coolant as soon as possible. Wait until the
engine has cooled.
Check the coolant level in the
coolant reservoir and/or radiator.
Level is OK.Level is low, check the
cooling system for leakage.
No
leakage.Leakage.
Ask a Yamaha dealer to inspect
and repair the cooling system.Add coolant. (See TIP.)
Restart the engine. If the engine overheats again, ask a
Yamaha dealer to inspect and/or repair the cooling system.
