The **cooling system** of an engine has the function of **removing part of the heat** generated when the engine is running. This is crucial to keep the engine at an appropriate temperature, preventing its parts from wearing out or breaking due to excessive heat.

- The system uses a **coolant** that circulates through the engine parts, absorbing the heat. Then, this liquid is cooled in the **radiator** and is pumped back into the engine by a **water pump**.

- It is important to ensure that the cooling system is working properly by checking that the water pump belts are in good condition and that there is enough coolant.

- Without this system, the engine would heat up quickly and could be damaged, which demonstrates the importance of its function to remove heat.


Therefore, the main function of the cooling system is precisely to **remove part of the heat produced in an engine**, ensuring its correct operation and longevity.
