The standard coolant mixture contains toxic chemicals that are harmful to the
human body. Never swallow neat antifreeze or any of the coolant mixture.
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.
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 suffer
severe damage.
Before starting work, ensure the motorcycle is stabilised and adequately
supported. This will help prevent it from falling and causing injury to the operator
or damage to the motorcycle.
Do not remove the coolant pressure cap when the engine is hot. When the engine
is hot, the coolant inside the radiator is hot and also under pressure. Contact with
hot coolant will cause scalds and skin damage.
Note
Prior to disassembly of the coolant hoses, note the orientation and position of
