What Is Coolant?

Coolant is a crucial component that helps to regulate the temperature of your vehicle’s engine. It is a liquid substance that flows through the engine and absorbs heat. As it travels through the engine, it picks up heat and carries it away to the radiator where it is dissipated.

Explanation Of Coolant

Coolant, also known as antifreeze, is a liquid that is typically mixed with water to regulate the engine’s temperature. Coolant is essential for ensuring that your engine doesn’t overheat during operation. It does this by absorbing the heat generated by the engine when it is running and carrying it away to the radiator where it is cooled down.

The primary function of coolant is to prevent your engine from overheating as this can cause significant damage to the engine components. Coolant also prevents the engine from freezing during the cold winter months by keeping it at a consistent temperature.

It is made up of various chemicals and additives that enhance its performance, including ethylene glycol or propylene glycol, which are the primary ingredients.

Types Of Coolant Available

There are two main types of coolant available, namely:

  • Inorganic acid technology (iat) coolant: This type of coolant is typically green in color and contains silicates as corrosion inhibitors. It is often used in older model vehicles and is not recommended for use in modern engines as it is not environment-friendly.
  • Organic acid technology (oat) coolant: This type of coolant is typically orange in color and does not contain silicates as corrosion inhibitors. It is often used in newer vehicles and is more environmentally friendly than iat coolant.

When selecting a coolant, it is important to check your vehicle’s owner manual to ensure that you are using the recommended type.

Importance Of Cooling Systems In Vehicles

The cooling system is a crucial component of your vehicle as it regulates the engine’s temperature during operation.
