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
antifreeze, and has a freezing point of
-31°F (-35°C).
Corrosion Inhibitors
Warning
HD4X Hybrid OAT coolant contains
corrosion inhibitors and antifreeze
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 antifreeze
or any of the motorcycle coolant.
Note
HD4X Hybrid OAT coolant, as supplied by
Triumph, is premixed and does not need
to be diluted prior to filling or topping
off the cooling system.
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.
Coolant Level Inspection
Note
The coolant level should be checked
when the engine is cold (at room or
ambient temperature).
