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 besufficiently 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.
NOTE:
The radiator fan is automatically
switched on or off according to the
coolant temperature in the radia-
tor.
If the engine overheats, see page6-31 for further instructions.

Changing the coolant
WARNING
EWA10380
Never attempt to remove the radiatorcap when the engine is hot.
The coolant must be changed at the in-
tervals specified in the periodic mainte-
nance and lubrication chart. Have a
Yamaha dealer change the coolant.

Air filter and V-belt case air
filter elements The air filter and V-belt case air filter el-
ements should be cleaned at the inter-
vals specified in the periodic
maintenance and lubrication chart.
Clean both filter elements more fre-
quently if you are riding in unusually
wet or dusty areas.CAUTION:
ECA10530
Make sure that each filter ele-
ment is properly seated in its
case.
The engine should never be op-
erated without the filter ele-
ments installed, otherwise the
piston(s) and/or cylinder(s) maybecome excessively worn.
Cleaning the air filter element
1. Place the scooter on the center-
stand.
2. Remove the air filter case cover by
removing the screws.
