Maintenance and Adjustment
119
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
authorised 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.
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.
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.
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
unauthorised 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.
