NOTE:The coolant should be between the minimum andmaximum level marks.
3. If the coolant is at or below the minimum level
mark, remove panel D. (See page 8-8.)
4. Remove the reservoir cap, add coolant or dis-
tilled water to the maximum level mark, install
the reservoir cap, and then install the panel.
CAUTION:ECB00400
If coolant is not available, use distilled water
or soft tap water instead. Do not use hard wa-
ter or salt water since it is harmful to the en-
gine.
If water has been used instead of coolant, re-
place it with coolant as soon as possible,
otherwise the engine may not be sufficiently
cooled and 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 con-
tent of the coolant as soon as possible, oth-
erwise the effectiveness of the coolant willbe reduced.
NOTE:
The radiator fan is automatically switched on or
off according to the coolant temperature in the
radiator.
