Engine Coolants: Selection and Maintenance


Coolant, also known as antifreeze, serves two major purposes: modulating temperature (through the transfer of heat) and protecting components against corrosion. In a heavy-duty diesel engine, for example, only one-third of the total energy produced is put towards propelling the vehicle; one-third of the energy is removed through the vehicle’s exhaust as heat energy; the final third of the heat energy produced is removed by the engine coolant. This is important because overheating can cause the engine and oil to rapidly degrade.

By choosing the right coolant for your needs and taking steps to properly maintain it, total ownership costs can be decreased due to reduced wear, decreased instances of failure, and longer engine or vehicle life.
