3. If the coolant is at or below the minimumlevel mark, remove the coolant reservoir
cap, add coolant to the maximum level
mark, install the reservoir cap. 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.
NOTICEECB02260Mix 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 8-56 for
instructions.EBU32400Axle bootsCheck the axle boots for holes or tears.
