There’s an entire cooling system at work under the hood of your car that helps it operate efficiently without overheating. The engine gets very hot while running, so the temperature must be regulated to prevent damage.
There are many parts that make up this cooling system, including the water pump, thermostat, hoses, fans and the radiator. The radiator is a heat exchanger that helps cool the engine.
Keep reading to find out more about how a radiator works and why it’s so important to the operation of your vehicle.
The radiator helps keep your vehicle cool, but how exactly does it achieve this goal?
The engine in a vehicle burns fuel and creates energy, which generates heat. Venting this heat away from engine parts is important to prevent damage.
Radiators work to eliminate heat from the engine. The process begins when the thermostat in the front of the engine detects excess heat. Then coolant and water get released from the radiator and sent through the engine to absorb this heat.
Once the liquid picks up excess heat, it is sent back to the radiator, which works to blow air across it and cool it down, exchanging the heat with the air outside the vehicle.
The radiator utilizes thin metal fins during the process, which are effective at allowing heat to quickly escape to the air outside the car. These fins are often working alongside the fan that’s blowing air across the radiator.
Long story short, the answer to “What’s a radiator in a car?” is simple — It is a heat exchange that cools fluid, which cools down the engine.
The radiator is located under the hood and in front of the engine. The coolant reservoir is located next to these components as well.
Here’s a diagram of a vehicle’s engine cooling system, including what a radiator looks like:

There are a few main parts that make up the radiator, and each plays a role in the cooling process. They are:
There are other important cooling system parts that work alongside your radiator, including the water pump and the thermostat.
As mentioned earlier, the thermostat regulates the engine’s temperature. If the engine needs to be cooled, the thermostat will open to allow an influx of coolant. It closes if the engine is at the proper operating temperature.
The water pump pushes the coolant through the system. This component is usually operated by the engine drive belt, which turns on the pump, and spinning blades force liquid through the system as needed. Gaskets and seals keep the coolant contained.
Coolant is also extremely important — it’s the fluid that gets pumped through the cooling system to prevent the engine from overheating. It also helps lubricate the different parts it contacts. You can read more about how coolant works here.
Over time, different parts of the cooling system can begin to wear down. For a more general overview, read up on the most common cooling system problems.
A few signs that your radiator specifically is having issues can include:
You can learn all about the maintenance and repair of a range of vehicle systems, including cooling systems, when you enroll in the Automotive Technology program at Universal Technical Institute (UTI).
Courses in UTI’s 51-week program can teach you the skills needed for an in-demand career in the industry.1 You’ll learn how to diagnose cooling system problems and how to work specifically on radiators.
