What three parts make up a radiator?

A radiator typically consists of three main components: the core, the tank, and the pressure cap.

The core is the central part of the radiator where the heat exchange occurs; it is where the coolant moves through tubes, allowing heat to dissipate into the air flowing over the fins. The tank, which is located at the ends of the core, serves as a reservoir for the coolant, helping to maintain the correct level and pressure within the system. The pressure cap is crucial because it maintains the pressure of the coolant system, allowing the radiator to operate efficiently and preventing coolant from boiling over or leaking.

This combination of parts ensures effective cooling of the engine by facilitating the transfer of heat from the coolant to the outside air, helping to maintain an optimal operating temperature. Understanding the function of each component is vital for diagnosing issues related to cooling systems in vehicles.
