Coolant

Before VIN AG0784, a year-round, Hybrid Organic Acid Technology (known as Hybrid OAT or HOAT) coolant was installed in the cooling system when the motorcycle left 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).

notice
Triumph HD4X Hybrid OAT coolant must not be mixed with Triumph D2053 OAT coolant.If the Triumph HD4X Hybrid OAT coolant is drained, fully flush the cooling system through before you fill the cooling system with the Triumph D2053 OAT coolant.

From VIN AG0784, Triumph D2053 OAT coolant is installed in the cooling system when the motorcycle leaves the factory. It is coloured orange, contains a 50% solution of ethylene glycol based antifreeze, and has a freezing point of -38°C (-36.4°F).

Triumph D2053 OAT coolant, as supplied by Triumph, is premixed and does not need to be diluted prior to filling or topping up the cooling system.

Always change the coolant at the intervals specified in the Scheduled Maintenance chart.

Warning Coolant - General Safety

warning
D2053 OAT coolant contains corrosion inhibitors and antifreeze suitable for aluminium engines and radiators. Always use the coolant in accordance with the instructions of the manufacturer.Coolant contains toxic chemicals that are harmful to the human body.Contact with skin or eyes may cause severe irritation. Wear protective gloves, clothing and eye protection when handling coolant. If coolant is inhaled, remove the person to fresh air and keep comfortable for breathing. In case of doubt or persistent symptoms, seek medical attention.If coolant gets on your skin, flush with water immediately. Remove contaminated clothing.If coolant gets in your eyes, flush with water for at least 15 minutes and SEEK MEDICAL ATTENTION IMMEDIATELY. If coolant is swallowed, rinse the mouth with water and SEEK MEDICAL ATTENTION IMMEDIATELY. KEEP COOLANT OUT OF THE REACH OF CHILDREN.Failure to follow the advice above could result in serious injury or death.
notice
The antifreeze used in the coolant mixture contains a corrosion inhibitor that helps prevent damage to the cooling system and engine.Without this inhibitor, the coolant would corrode the metals and cause blockages in the cooling system that could lead 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.
notice
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 engine to overheat and cause severe damage.
