5B410015Coolant
The coolant level should be checked before
each ride.
Checking the coolant level1. Park the vehicle on a level surface.
2. Check the coolant level in the coolant
reservoir when the engine is cold as the
coolant level varies with engine tempera-
ture. TIPThe coolant should be between the minimum
and maximum level marks.
1. Coolant reservoir cap
2. Maximum level mark 3. Minimum level mark3. If the coolant is at or below the minimum level mark, remove the coolant reservoir
cap, add coolant to the maximum level
mark, install the reservoir cap.
Coolant reservoir capacity
(up to the maximum level mark): 0.32 L (0.34 US qt, 0.28 Imp.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.NOTICEMix 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 8-63 for
instructions.
