Which system is responsible for controlling the engine temperature and preventing overheating?

The cooling system is essential for managing the engine temperature and preventing overheating. It achieves this by circulating coolant through the engine, where it absorbs excess heat generated during operation. The flow of coolant is regulated to maintain an optimal engine temperature, ensuring that the engine operates efficiently and reducing the risk of damage that could occur from overheating.

In comparison, the fuel system's primary function is to supply fuel to the engine for combustion, while the ignition system is responsible for igniting the fuel-air mixture to initiate the engine's operation. The lubrication system plays a critical role in reducing friction between moving parts and ensuring smooth operation but does not directly control engine temperature. These systems have distinct functions, but only the cooling system specifically addresses the need to regulate and manage heat levels in the engine.
