Coolant

The coolant level should be checked
before each ride. In addition, the cool-
1
ant must be changed at the intervals
specified in the periodic maintenance
and lubrication chart.
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 temperature.

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 cool-
ant reservoir.
TIP
The coolant should be between the
minimum and maximum level marks.
