The Parts of the cooling cycle in a vehicle


Car cooling cycle

  • The cooling cycle in the car contains some parts that play an essential role in cooling the engine and expelling the heat resulting from the combustion process, and it is as follows: Volume 0%
  • Radiator: It is a heat exchanger consisting of many small channels, and it expels the heat coming from the engine and stored inside the coolant to the external environment.
  • Coolant pump: It pumps the coolant inside the system to form the cooling cycle, and the pump is operated by connecting it with a rubber belt with the engine.
  • Thermostat: A thermostat coolant controls engine temperature by controlling the amount of coolant flow to the engine.
  • Fan: It pumps air onto the radiator to speed up the process of expelling heat from the system.
  • Heat sensor: its primary function is to control the electric fan of the system by sensing the engine temperature to turn the fan on or to increase its speed.
  • Connection pipes: They are rubber hoses whose function is to transport coolant between parts of the system.


The working principle of the cooling system

The car engine produces much heat during the fuel-burning process to produce mechanical energy. Thus the engine cooling system absorbs that heat from the engine and then expels it out by pumping the coolant into the system to absorb the heat from the engine and then transfer it to the radiator, which in turn works On the heat exchange between the liquid inside it and the outside environment.


How to check the engine cooling system

The car’s cooling system can check, and the coolant level is checked by following the following:

  • Park the car in a flat place.
  • Ensure that the engine temperature is low.
  • Open the radiator cap if possible and make sure that the coolant is visible and up to the top.
  • Look at the system’s coolant reservoir and make sure that the liquid has reached the full mark.
