Coolant (or antifreeze) protects your engine from freezing while defending components against corrosion. It plays a critical role in sustaining 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 engine coolant.

This heat removed by the coolant provides a balance in the removal of engine heat that is critical in ensuring that the engine operates properly. Overheating could result in accelerated deterioration of the oil and the engine itself.

Why Coolant is Important

Without a coolant, the heat produced through constant internal combustion would destroy the engine very quickly. Water alone is not enough to keep the system cool, for the high temperatures inside the motor would eventually boil and evaporate it entirely. Likewise, in very cold weather, the water would freeze when the car is sat idle, rendering the cooling system useless. A coolant is therefore important as the synergy between glycols and water enable it to perform in cold and hot environments, all year round. The extra additives present in a coolant also provides protection against corrosion.
