A year-round, Hybrid Organic Acid Technology (known as Hybrid OAT or HOAD coolant is installed in the cooling system. lt is coloured green, contains a 50% solution of ethylene glycol based antifreeze, and has a freezing point of -35°C (-31°F)..
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.
All models
Always change the coolant at the intervals specified in the scheduled maintenance chart.
Warning: The coolant mixture contains anti-freeze and corrosion inhibitors, which both contain toxic chemicals which are harmful to the human body. Never swallow anti-freeze or any of the motorcycle coolant.
Caution: The coolant mixture contains a corrosion inhibitor which helps prevent damage to the metal surfaces inside the coqling system. 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 correct antifreeze as specified in the owner's handbook. Never use a methanol based anti-freeze as this does not contain the required corrosion inhibition properties.
Caution: Distilled water must be used with the anti-freeze (see specification for anti-freeze) in the cooling system. If hard water is used in the system, it causes scale accumulation in the water passages, and considerably reduces the efficiency of the cooling system. Reduced cooling system efficiency may cause the engine to overheat and suffer severe damage.
Radiator Hoses
Regularly check all radiator hoses and hose clips for cracks, leaks or deterioration in accordance with the scheduled maintenance chart.
