CAUTION:
ECA10470
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 engine may not be
sufficiently cooled and the cool-
ing 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.
5. Install the panel.NOTE:
The radiator fans are automatically
switched on or off according to the
coolant temperature in the radia-
tor.
If the engine overheats, see page6-42 for further instructions.
EAU39001
To change the coolant
1. Place the vehicle on a level sur-
face and let the engine cool if nec-
essary.
2. Remove cowlings D and E. (See
page 6-6.)3. Place a container under the engine
to collect the used coolant.
4. Remove the radiator cap.
WARNING
EWA10380
Never attempt to remove the radiatorcap when the engine is hot.
5. Remove the coolant drain bolt to
drain the cooling system.
6. Move the hose clamp in the direc-
tion shown, and then disconnect
the radiator hose to drain the radi-
ator.

6 7. Remove the coolant reservoir by
removing the bolts.
8. Remove the coolant reservoir cap,
and then turn the coolant reservoir
upside down to empty it.9. After the coolant is completely
drained, thoroughly flush the cool-
ing system with clean tap water.
10. Install the coolant reservoir by in-
stalling the bolts.
11. Connect the radiator hose, and
then move the hose clamp back to
its original position.
12. 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.13. Pour the recommended coolant
into the reservoir to the maximum
level mark, and then install the
coolant reservoir cap.
14. Pour the recommended coolant
into the radiator until it is full.
