Coolant
The coolant level should be checked
before each ride. In addition, the cool-
ant must be changed at the intervals
specified in the periodic maintenance
and lubrication chart.
EAUM3045To check the coolant level
1. Place the vehicle on a level sur-
face and hold it in an upright posi-
tion.
2. Open the front storage compart-
ment A. (See page 3-21.)
TIP
The coolant level must be
checked on a cold engine since
the level varies with engine tem-
perature.
Make sure that the vehicle is posi-
tioned straight up when checking
the coolant level. A slight tilt to the
side can result in a false reading.
3. Check the coolant level through
the check window.
TIP
The coolant should be between the
minimum and maximum level marks.
4. If the coolant is at or below the
minimum level mark, remove pan-
el A. (See page 6-7.)
5. 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.
[EWA15162] NOTICE: If coolant is not
available, 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 cool-
ant as soon as possible, other-
wise the cooling system will not
be protected against frost and
corrosion. 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.
