(up to the maximum level mark):
0.32 L (0.28 Imp qt, 0.34 US qt)
Changing the coolant
The coolant must be changed by a Yamaha
dealer at the intervals specified in the periodic
maintenance and lubrication chart.
Adding water instead of coolant lowers the
antifreeze content of the coolant. If water is
used instead of coolant, have a Yamaha deal-
er check the antifreeze content of the coolant
as soon as possible.
The radiator fan is automatically switched on
or off according to the coolant temperature in
the radiator.
NOTICE
Mix antifreeze with distilled water only.
However, if distilled water is not available,
soft water may be used for refilling.
If your vehicle overheats, see page 8-60 for
