Maintenance
174
To adjust the coolant level:
• Allow the engine to cool.
• The expansion tank cap can be
removed from the left hand side of
the motorcycle.
• Remove the expansion tank cap
from the expansion tank and add
coolant mixture through the filler
opening until the level reaches the
MAX mark.
• Reinstall the expansion tank cap.
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.
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.
Coolant Change
It is recommended that the coolant is
changed by an authorised Triumph
dealer in accordance with scheduled
maintenance requirements.
Radiator and Hoses
Warning
The fan operates automatically when
the engine is running. Always keep
hands and clothing away from the fan
as contact with the rotating fan can
cause injury.
Caution
Using high pressure water sprays,
such as from a car wash facility or
household pressure washer, can
damage the radiator fins, cause leaks
and impair the radiator's efficiency.
Do not obstruct or deflect airflow
through the radiator by installing
unauthorized accessories, either in
front of the radiator or behind the
cooling fan. Interference with the
radiator airflow can cause overheating,
potentially resulting in engine damage.
Check the radiator hoses for cracks or
deterioration, and hose clips for
tightness in accordance with scheduled
maintenance requirements. Have your
authorized 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.
