Maintenance and Adjustment
142
Position the motorcycle on level ground
and in an upright position. The
expansion tank can be viewed from the
left hand side of the motorcycle.
Check the coolant level in the expansion
tank. The coolant level must be between
the MAX and MIN marks. If the coolant is
below the minimum level, the coolant
level must be adjusted.
Coolant Level Adjustment
1. Expansion tank
2. Expansion tank cap
Allow the engine to cool.
The expansion tank cap can be removed
from the left 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 MAX mark. Refit the cap.
Note:
• If the coolant level is being checked
because the coolant has overheated,
also check the level in the radiator
and top up 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.
Coolant Change
Have the coolant changed by an auth-
orised Triumph dealer in accordance with
scheduled maintenance requirements.
Radiator and Hoses
Check the radiator hoses for cracks or
deterioration, and hose clips for
tightness in accordance with scheduled
maintenance requirements. Have your
authorised Triumph dealer replace any
defective items.
Check the radiator grille and fins for
obstructions by insects, leaves or mud.
Clean off any obstructions with a stream
of low-pressure water.
Warning
Do not remove the 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,
pressurised 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.
