Maintenance and Adjustment
Cooling System
To ensure efficient engine cooling, check the
coolant level each day before riding the
motorcycle, and top up 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
coloured green, contains a 50%
solution of ethylene glycol based
antifreeze, and has a freezing
point of -35°C (-31°F).
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 up the
cooling system.
Warning
HD4X Hybrid OAT coolant contains
corrosion inhibitors and anti-freeze suitable
for aluminium 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.
