6 5. Remove the coolant reservoir
breather hose from the guide, and
then remove the coolant reservoir
cap.
6. Remove the coolant reservoir cov- er and coolant reservoir by remov-
ing the bolts. 7. Drain the coolant from the coolant
reservoir by turning it upside
down.
8. Remove the coolant drain bolt and its gasket to drain the cooling sys-
tem.
9. After the coolant is completely drained, thoroughly flush the cool-
ing system with clean tap water.
10. Install the coolant drain bolt and its new gasket, and then tighten
the bolt to the specified torque.

11. Install the coolant reservoir and its
cover by placing them in the origi-
nal position, and then installing the
bolts.
12. Pour the specified amount of the recommended coolant into the ra-
diator and reservoir.
13. Install the radiator cap.
14. Install the coolant reservoir cap.
15. Start the engine, let it idle for sev- eral minutes, and then turn it off.
16. Remove the radiator cap to check the coolant level in the radiator. If
necessary, add sufficient coolant
until it reaches the top of the radi-
ator, and then install the radiator
cap, radiator cap retainer and ra-
diator cap retaining bolt. 17. Check the coolant level in the res-
ervoir. If necessary, remove the
coolant reservoir cap, add coolant
to the maximum level mark, and
then install the cap.
18. Route the coolant reservoir breather hose through the guide
as shown.
19. Start the engine, and then check the vehicle for coolant leakage. If
coolant is leaking, have a Yamaha
dealer check the cooling system.
20. Install the cowling and the panel.

WARNING
EWA10401
Do not remove the ra diator cap when the en gine an d ra diator are hot.
Scal din g hot flui d an d steam may b e blown out un der pressure, which
coul d cause serious injury. Be sure to wait until the eng ine has cooled.
 After removin g the ra diator cap retainin g b olt, place a thick rag , like a
towel, over the ra diator cap, an d then slowly rotate the cap counter-
clockwise to the d etent to allow any resi dual pressure to escape. When
the hissin g sound has stopped , press down on the cap while turnin g it
counterclockwise, an d then remove the cap.
TIP
If coolant is not available, tap water can be temporarily used instead, 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 reservoir
and radiator.Add coolant.
(See TIP.)
The coolant level is
OK.
There is no leakage.
There is leakage.
The coolant level is
low.
Check the cooling
system for leakage.
Have a Yamaha
dealer check and
repair the cooling
system.
Start the engine. If the engine overheats again,
have a Yamaha dealer check and repair the cooling
system.
