What is the role of the radiator in an engine's cooling system?

The radiator plays a crucial role in an engine's cooling system by dissipating heat from the coolant. As the engine operates, it generates a significant amount of heat. The coolant absorbs this heat and travels through the engine to the radiator, where it is cooled down. The radiator consists of a series of tubes and fins that allow air to flow over its surface, effectively transferring the heat from the coolant to the outside air. This process ensures that the engine remains within its optimal operating temperature range, preventing overheating and maintaining efficiency. The ability to manage the engine's temperature is vital for its performance and longevity.
