What component absorbs heat from the engine and then passes it to be cooled?

The radiator is the component responsible for absorbing heat from the engine and then dissipating that heat to be cooled. In an automotive cooling system, the engine generates considerable heat while operating. The coolant flows through the engine and absorbs this heat, raising its temperature. The heated coolant then travels to the radiator, where it is exposed to airflow, typically from the vehicle's motion or a fan.

As the coolant passes through the radiator's many tubes and fins, the heat is transferred to the surrounding air, allowing the coolant to cool down before it returns to the engine to repeat the cycle. This process is crucial for maintaining optimal engine temperature, preventing overheating, and ensuring efficient engine performance.

The other components listed play different roles: the oil pump circulates engine oil to lubricate moving parts, the water pump moves coolant throughout the system, and the starter is used to turn the engine over when starting.
