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.
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.
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.
