3. If the coolant is at or below the
minimum level mark, remove pan-
el C (See page 6-7.), remove the
reservoir cap, add coolant to the
maximum level mark, and then in-
stall the reservoir cap and the pan-
el.
WARNING! Remove only the
coolant reservoir cap. Never at-
tempt to remove the radiator
cap when the engine is
hot.

[EWA15161]

NOTICE:
If coolant is
not available, use distilled water
or soft tap water instead. Do not
use hard water or salt water
since it is harmful to the engine.
If water has been used insteadof coolant, replace it with cool-
ant as soon as possible, other-
wise the cooling system will not
be protected against frost and
corrosion. If water has been
added to the coolant, have a
Yamaha dealer check the anti-
freeze content of the coolant as
soon as possible, otherwise the
effectiveness of the coolant will
be reduced.

To change the coolant
1. Place the vehicle on a level sur-
face and let the engine cool if nec-
essary.
2. Remove panels A and C. (See
page 6-7.)
3. Place a container under the engine
to collect the used coolant.
4. Remove the radiator cap retaining
bolt and radiator cap.

6. Remove the coolant reservoir cap.
7. Drain the coolant from the coolant
reservoir by turning it upside down.
8. Install the coolant reservoir by
placing it in the original position,
and then installing the bolts.9. Remove the coolant drain bolt to
drain the cooling system.
10. After the coolant is completely
drained, thoroughly flush the cool-
ing system with clean tap water.
11. Install the coolant drain bolt, and
then tighten it to the specified
torque.
TIP

Check the washer for damage and re-
place it if necessary.
12. Pour the specified amount of therecommended coolant into the ra-
diator and reservoir.
13. Install the coolant reservoir cap.
14. Install the radiator 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 radia-
tor, and then install the radiator
cap and its 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
