Coolant
The coolant level should be checked before each
ride.
Checking the coolant level
1. Place the vehicle on a level surface.
2. Open the hood. (See pages 8-17–8-19 for
hood opening and closing procedures.)
3. Check the coolant level in the coolant reser-
voir when the engine is cold as the coolant
level varies with engine temperature.NOTE:_ The coolant should be between the minimum and
maximum level marks. _4. If the coolant is at or below the minimum level
mark, remove the reservoir cap, add coolant
to the maximum level mark, install the reser-
voir cap, and then close the hood.
Coolant reservoir capacity
(up to the maximum level mark):
0.35 L (0.31 Imp qt, 0.37 US qt)

CAUTION:_ Mix antifreeze with distilled water only. Howev-
er, if distilled water is not available, soft water
may be used for refilling._Changing the coolant
The coolant must be changed by a Yamaha dealer
at the intervals specified in the periodic mainte-
nance and lubrication chart.NOTE:_ Adding water instead of coolant lowers the anti-
freeze content of the coolant. If water is used in-
stead of coolant, have a Yamaha dealer check the
antifreeze content of the coolant as soon as possi-
ble. _If your vehicle overheats, see page 8-136 for de-
tails.
