To inspect the coolant level:
Position the motorcycle on level ground
and in an upright position.
The expansion tank can be viewed from
the right hand side of the motorcycle,
towards the rear of the engine.
Check the coolant level in the expansion
tank.
The coolant level must be between the
maximum (top) and minimum (bottom)
marks. If the coolant is below the
minimum level, the coolant level must be
adjusted.
Coolant Level Adjustment
Warning
Do not remove the expansion tank or
radiator pressure cap when the engine
is hot. When the engine is hot, the
coolant inside the radiator will be hot
and also under pressure. Contact with
this hot, pressurized coolant will cause
scalds and skin damage.
Caution
If hard water is used in the cooling
system, it will cause scale accumulation
in the engine and radiator and
considerably reduce the efficiency of
the cooling system. Reduced cooling
system efficiency may cause the
engine to overheat and suffer severe
damage.
Note:
• If the coolant level is being checked
because the coolant has overheated,
also check the level in the radiator
and top off if necessary.
• In an emergency, distilled water
can be added to the cooling system.
However, the coolant must then be
drained and replenished with HD4X
Hybrid OAT coolant as soon as
possible.

To adjust the coolant level:
Position the motorcycle on level ground
and in an upright position.
Allow the engine to cool.
Disconnect the battery, see page
96.
Remove the sprocket cover on the right
hand side of the motorcycle.
Remove the cap from the expansion
tank and add coolant mixture through
the filler opening until the level reaches
the maximum (top) mark.
Re-install the cap.
