Maintenance and Adjustment
Cooling System
To ensure efficient engine
cooling, check the coolant
level each day before riding
the motorcycle, and top off
the coolant if the level is low.
Note:
•
A year-round, Hybrid Organic Acid
Technology (known as Hybrid OAT
or HOAT) coolant is installed in the
cooling system when the motorcycle
leaves the factory. It is colored
green, contains a 50% solution of
ethylene glycol based anti-freeze,
and has a freezing point of -31°F
(-35°C).
Corrosion Inhibitors
To protect the cooling system from corrosion,
the use of corrosion inhibitor chemicals in the
coolant is essential.
If coolant containing a corrosion inhibitor is
not used, the cooling system will accumulate
rust and scale in the water jacket and radiator.
This will block the coolant passages, and
considerably reduce the efficiency of the
cooling system.
Note:
•
HD4X Hybrid OAT coolant, as
supplied by Triumph, is pre-mixed
and does not need to be diluted
prior to filling or topping off the
cooling system.

Warning
HD4X Hybrid OAT coolant contains
corrosion inhibitors and anti-freeze suitable
for aluminum engines and radiators.
Always use the coolant in accordance with
the instructions of the manufacturer.
Coolant that contains anti-freeze and
corrosion inhibitors contains toxic
chemicals that are harmful to the human
body. Never swallow anti-freeze or any of
the motorcycle coolant.
