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.
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
Have the coolant changed by an
authorized
Triumph

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

Check the radiator grille and fins for
obstructions by insects, leaves or mud.
Clean off any obstructions with a
stream of low pressure water.
