PERIODIC MAINTENANCE AND MINOR REPAIR

EC000080
•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
coolant as soon as possible,
otherwise the engine may not
be sufficiently cooled and the
cooling system will not be
protected against frost and cor-
rosion.
•If water has been added to the
coolant, have a Yamaha dealer
check the antifreeze content of
the coolant as soon as possi-
ble, otherwise the effectiveness
of the coolant will be reduced.
EW000067
Never attempt to remove the radiator
cap when the engine is hot.
CAUTION:
WARNING
EAU01808*
Coolant
To check the coolant level
1. Place the scooter on a level sur-
face and hold it in an upright po-
sition.
NOTE :
•The coolant level must be
checked on a cold engine since
the level varies with engine
temperature.
•Make sure that the scooter is
positioned straight up when
checking the coolant level. A slight
tilt to the side can result in a false
reading.
2. Remove cowling A. (See page
6-5 for cowling removal and ins-
tallation procedures.)3. Check the coolant level in the
coolant reservoir.
NOTE :
The coolant should be between the
minimum and maximum level marks.
4. If the coolant is at or below the
minimum level mark, open the
reservoir cap, add coolant to the
maximum level mark, and then
close the reservoir cap.
Coolant reservoir capacity:
0.25 L
