Coolant

Radiator coolant is a liquid solution used to regulate the temperature of an internal combustion engine. It circulates through the engine and the radiator, absorbing heat from the engine and transferring it to the air outside the vehicle.

Coolant can be made from a variety of substances, including water, ethylene glycol, and propylene glycol. It also typically contains additives that protect the engine from corrosion and deposit formation.

Choosing the right coolant for a vehicle depends on factors such as the make and model of the vehicle, the type of engine, and the climate. Some important considerations include:

Antifreeze properties: the ability of the coolant to prevent the engine from freezing in cold temperatures.
Boiling point: the temperature at which the coolant begins to boil, which can affect its ability to transfer heat effectively.
Compatibility: it is important to choose a coolant that is compatible with the materials used in the engine, such as aluminum and copper.
