TIP
The coolant should be between the
minimum and maximum level marks.
1. Maximum level mark
2. Minimum level mark
3. Coolant level check window
3. If the coolant is at or below the
minimum level mark, lift up the
right floorboard mat as shown.
1. Floorboard mat
4. Open the reservoir cap, and then
add coolant to the maximum
level mark. WARNING! Remove
only the coolant reservoir cap.
Never attempt to remove the
radiator cap when the engine is
hot.
[EWA15161]
NOTICE: If coolant is not avai-
lable, use distilled water or soft
tap water instead. Do not use
hard water or salt water since it
is harmful to the engine. If
water has been used instead of
coolant, replace it with coolant
as soon as possible, otherwise
the cooling system will not be
protected against frost andcorrosion. If water has been
added to the coolant, have a
Yamaha dealer check the anti-
freeze content of the coolant
as soon as possible, otherwise
the effectiveness of the coolant
will be reduced.
