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.
EAU50543
To check the coolant level
1. Place the vehicle on the center-
stand.
2. Remove cowling A. (See page
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 in the
coolant reservoir.
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
cowling C. (See page 6-7.)
5. Remove the coolant reservoir
breather hose from the guide, and
then remove the coolant reservoir
cap.
WARNING! Remove only
the coolant reservoir cap. Never
attempt to remove the ra
d
iator
cap when the en
g
ine is hot.
