A radiator is a crucial component of a vehicle’s cooling system. Its primary function is to monitor and regulate the engine’s temperature, preventing it from overheating. Here’s how it works:

1. Heat Exchange: The radiator acts as a heat exchanger. It transfers heat from the engine coolant (which absorbs heat from the engine) to the surrounding air. This process keeps the engine at an optimal operating temperature.

2. Coolant Flow: The engine coolant (usually a mixture of water and antifreeze) circulates through the engine, absorbing heat. It then flows into the radiator through hoses.

3. Fins and Tubes: Inside the radiator, there are finned tubes. These tubes allow the coolant to flow while maximizing its surface area. The fins help dissipate heat efficiently.

4. Airflow: As the vehicle moves, air passes through the radiator. The heat from the coolant is transferred to the air, cooling the coolant down.

5. Thermostat: The thermostat regulates the coolant flow. When the engine is cold, the thermostat keeps the coolant within the engine. As the engine warms up, it opens, allowing coolant to flow into the radiator.

6. Fan: Some vehicles have an electric fan behind the radiator. It turns on when the engine temperature rises, enhancing airflow through the radiator.

7. Regular Maintenance: To maintain optimal performance, it’s essential to flush the radiator periodically. Flushing removes any buildup of sediment or contaminants that can hinder heat exchange.
