How Does The Cooling System Work

First of all, let's start with a simple explanation of what the cooling system does. As the name implies, its main job is to cool and keep parts from overheating. The parts we are talking about are all of the moving components in an engine - from the cylinders to the block itself. This is done by the constant circulation of a coolant liquid through a closed loop. We will take a look at the main components of a cooling system and what they exactly do, down below.

Main components of the cooling system:

  • Engine block
  • Coolant
  • Pipes
  • Radiator
  • Cooling fan
  • Heater
  • Sensors
  • Thermostat
  • Water pump

The engine block serves as the foundation of the cooling system, allowing coolant to flow freely through its holes and crevasses. It is made of metal, allowing it to aid in heat dissipation, ensuring optimal cooling performance.

The cooling system operates by circulating a liquid to collect and transfer heat. Typically, the coolant consists of filtered water with a small amount of antifreeze. Pipes connect all the components, creating a loop that facilitates the movement of the coolant.

At the heart of the system is the radiator, a thin metal structure designed to efficiently cool the liquid. Situated in the front of the vehicle, it is complemented by fans that draw in cold air. Both the radiator and fans are visible through the grills.

Contrary to its name, the heater does not actively cool anything. Instead, it plays a role in the air conditioning system by providing heat when required. It captures heat from the loop and disperses it into the air using fans.

Lastly, we have the pump, a vital component responsible for circulating the liquid throughout the system. Depending on the vehicle, the pump may be driven by an auxiliary belt connected to the engine or operate independently.

These components work in harmony to ensure the efficient functioning of the vehicle's cooling system, effectively managing heat and maintaining optimal engine temperatures.
