It is a heat transfer fluid used to prevent its overheating, transferring the heat produced by the engine.
Coolant a.k.a antifreeze, protects your engine from freezing while defending components against corrosion,
as well as plays a critical role in sustaining overall engine heat balance by removing heat. In a heavy-duty
diesel engine, only one-third of the total energy produced works to propel the vehicle forward.
An additional one-third is removed as heat energy by the exhaust system. The remaining one-third of heat
energy produced is taken away by the coolant. This heat removed by the coolant provides a balance in the overall
removal of engine heat that is critical in ensuring that the engine operates properly. Overheating could result
in accelerated deterioration of the oil and subsequently the engine itself.
