1. Coolant reservoir cap
Coolant reservoir capacity (up to the
maximum level mark):
0.25 L (0.26 US qt) (0.22 Imp.qt)
CAUTION:
G 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.
G
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.
G
If water has been added to the
6-13
coolant, have a Yamaha dealer
check the antifreeze content of
the coolant as soon as possible,
otherwise the effectiveness of
the coolant will be reduced.
WARNING
Never attempt to remove the radiator
cap when the engine is hot.
NOTE:
G The radiator fan is automatically
switched on or off according to the
coolant temperature in the radia-
tor.
