Understanding the Importance of Coolant in Vehicles
Coolant, also known as antifreeze, is a vital component in a vehicle’s cooling system. Its primary function is to regulate the engine’s temperature by absorbing heat from the engine block and transferring it to the radiator, where it is dissipated. Coolant also prevents the engine from freezing in cold temperatures.
However, not all coolants are created equal, and different vehicles require different types of coolants. In this section, we will explore the different types of coolants and their applications.
The Three Main Types of Coolants
There are three main types of coolants used in vehicles: ethylene glycol, propylene glycol, and organic acid technology (OAT) coolants.
Ethylene Glycol Coolants
Ethylene glycol coolants are the most commonly used coolants in vehicles. They are inexpensive and effective at low temperatures. However, they can be toxic to humans and animals if ingested, and they can also damage the environment if not disposed of properly.
