How does Car Engine Cooling Work?

The mechanical and chemical elements of your car’s engine forces it to take heavy temperature levels on a regular basis, so it should have parts and features that keep it from burning up, especially on long drives during a hot day. This is where the engine cooling system comes into play: essentially it is composed of various parts that work together to keep the engine’s temperature at bay.


The main parts that make up an engine’s cooling system are the radiator, fan, pressure cap, thermostat, pumps, and the overflow tank. The pump delivers a cooling fluid to the engine, effectively absorbing the heat. A thermostat monitors the fluid as it exits the engine, and when its (the coolant’s) temperature is lower than the maximum, the thermostat reroutes the fluid for another pass.


Engine coolants basically perform three major functions, to keep the engine from overheating, prevent it from freezing and protect the aluminum components of the engine. Many manufacturers like Baldwin Filters provide coolant fluid to car repair or maintenance specialists nationwide.

Air Cooling

While a vast majority of car engines are liquid cooled, there are many today that use air cooling. In this system, the main features are aluminum fins all around the engine. When the engine is at risk of overheating, the fans turn, cooling the engine’s cylinder in the process.
