Radiator Hoses
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).
Always change the coolant at the intervals specified in the Scheduled Maintenance chart.
WARNING
The standard coolant mixture contains toxic chemicals that are harmful to the human body. Never swallow
neat antifreeze or any of the coolant mixture.
CAUTION
The antifreeze incorporated in the coolant mixture contains a corrosion inhibitor that helps prevent damage
to the cooling system and engine. Without this inhibitor, the coolant would 'attack' the metals and the
resulting corrosion would cause blockages in the cooling system leading to engine overheating and damage.
Always use the antifreeze listed in the Specification section and never use a methanol based antifreeze as
this does not contain the required corrosion inhibition properties.
Note
HD4X Hybrid OAT coolant, as supplied by Triumph, is premixed and does not need to be diluted prior
to filling or topping up the cooling system.
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
