What is Coolant?
Coolant is a liquid substance designed to regulate the temperature of a vehicle’s engine. It is typically a mixture of water and antifreeze, such as ethylene glycol or propylene glycol, that is pumped through the engine block, cylinder head, and radiator. The coolant’s primary function is to absorb heat from the engine and transfer it to the radiator, where it is dissipated through the cooling fan.
There are different types of coolants available, including conventional, long-life, and organic acid technology (OAT) coolants. Each type has its own set of characteristics and benefits, and the choice of coolant will depend on the vehicle manufacturer’s recommendations and the climate in which the vehicle is operated.
