What Does A Radiator Do In A Car?

So, what does a radiator do in a car? According to kia.com, a radiator is a key component in a vehicle that acts as part of the cooling system in the engine. In this system, the radiator’s role is to disperse antifreeze and water through the fins to cool the engine by releasing heat and taking in some cool air.

How Does A Radiator Work?

The radiator’s function is to keep heat out of the engine. The engine produces heat, and the radiator works to vent that heat from the system to stop it from becoming too much and killing the car. It’s a little assistance to the most critical part of a car.

According to uti.edu, the radiator functions by leasing coolant and water from its system when the thermostat at the front of the engine detects a specific temperature. These items go through the engine, and they work to absorb some of the heat.

The liquid in the system grabs onto the excess heat. Once it does that, it goes back to the radiator. The radiator then works to cool down the components and exchanges them for air from the outside.

The thin metal blades on the radiator are critical in how the system functions. They help it work the air efficiently and effectively.
