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.
EAU78580To check the coolant level
1. Place the vehicle on the center- stand.
TIP
zThe coolant level must be
checked on a cold engine since
the level varies with engine tem-
perature.
z 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 through
the check window.
TIP
The coolant should be between the mi-
nimum and maximum level marks.
3. If the coolant is at or below the mi-nimum level mark, remove the left
floorboard mat by pulling it up.
4. Remove the coolant reservoir cov- er.
5. 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 diator
cap when the en gine is hot.
[EWA15162] NOTICE: If coolant is not
availa ble, use distille d water or
soft tap water instea d. Do not
use har d water or salt water
since it is harmful to the en gine.
