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.
EAUN0690
To check the coolant level
1. Place the vehicle on a level sur-
face and hold it in an upright posi-
tion.
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.
2. Check the coolant level in the
coolant reservoir.
TIP
The coolant should be between the
minimum and maximum level marks.
3. If the coolant is at or below the
minimum level mark, remove the
left side cowling and coolant res-
ervoir cover to access the coolant
reservoir.
4. Remove the coolant reservoir cap,
add coolant to the maximum level
mark, and then install the 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.
