What is a car radiator?

A radiator in a car is a crucial component of the engine's cooling system. It's designed to dissipate excess heat from the engine, preventing it from overheating.

Here's how it works:

 * Coolant Circulation: A mixture of water and antifreeze, known as coolant, flows through the engine's cooling system.

 * Heat Absorption: As the coolant circulates, it absorbs heat from the engine's hot parts.

 * Radiator Transfer: The heated coolant then travels to the radiator.

 * Heat Dissipation: Inside the radiator, the coolant passes through a network of tubes and fins. As air flows over the fins, it cools the coolant, transferring the heat to the outside environment.

 * Coolant Return: The now-cooled coolant returns to the engine to repeat the process, maintaining a safe operating temperature.

Think of it like a car's air conditioner, but for the engine. By effectively removing excess heat, the radiator helps ensure the engine runs efficiently and prevents potential damage.
