If the cooling fluid is below the maximum temperature, the thermostat stays closed and the fluid is re-routed back to the pump. However, if the fluid is overheated, the thermostat’s valve opens, routing the fluid through a radiator first. The radiator cools the fluid by releasing its heat to the air before returning it to the pump.
How does a car's cooling system work?
With a cooling system based on liquid, fluid contained in pipes passes through the engine, absorbing heat while cooling the engine. If the fluid gets overheated, it’s routed through the radiator, which acts as a heat exchanger, releasing the surplus heat to the air. On the other hand, a cooling system based on air has aluminum fins surrounding the engine. When the engine gets overheated, fans blow air over the fins to conduct the heat away from the engine’s cylinder, cooling it down.
