6 4. Add coolant or distilled water to
raise the coolant to the maximum
level mark, install the coolant res-
ervoir cap.
CAUTION:
ECA10471
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 instead
of 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 antifreeze content of
the coolant as soon as possible,
otherwise the effectiveness ofthe coolant will be reduced.WARNING
EWA10380
Never attempt to remove the radiatorcap when the engine is hot.NOTE:
The radiator fan is automatically
switched on or off according to the
coolant temperature in the radia-
tor.
If the engine overheats, see page6-37 for further instructions.
EAU40133
To change the coolant
1. Place the vehicle on the center-
stand and let the engine cool if
necessary.
2. Remove panel A. (See page 6-6.)3. Place a container under the engine
to collect the used coolant.
4. Remove the radiator cap retaining
bolt, radiator cap retainer and radi-
ator cap.
WARNING

Never attempt to remove the radiatorcap when the engine is hot.
5. Remove the coolant reservoir cap.

66. 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. Install the coolant reservoir and its
reservoir cover by placing them in
the original position, and then in-
stalling 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.
NOTE:Check the washer for damage and re-place it if necessary.12. Pour the specified amount of the
recommended coolant into the ra-
diator and reservoir.
CAUTION:

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.
