What Does Your Radiator Do

Your radiator

During the operation, the engine creates a lot of heat. To avoid the engine from overheating, your car pumps coolant through the engine - the fluid that receives heat and carries it away from the engine block. The generated heat moves to your radiator with coolant. The radiator is cooling it down and exchanging heat with the air outside your car.

The radiator works by passing the coolant through thin metal fins, which allows the heat to flow to the air outside your car much more easily. There can also be a fan that blows air across the radiator in order to carry the hot air out of your vehicle. All radiators do the same job, doesn’t matter the size, or their design. So the radiator is the essential part that cools the coolant, which then cools your vehicle’s engine.

Parts of a Radiator

Core: The main cooling component of the Radiator is the Core . It is the largest component piece of the radiator which is made up of a series of Tubes and Cooling Fins. These fins allow the coolant to vent heat to the air surrounding the radiator. There are many types of radiators, for example, one-core, two-core, or even three-core radiators.

Pressure cap: The radiator pressure cap prevents coolant loss and increases the cooling system’s boiling point. When the pressure inside the cooling system increases above its psi rating, the pressure cap releases some of the coolant into the overflow tank. It does this by use of a spring loaded valve. Once enough coolant has exited the system to reduce the pressure, the valve closes again.

Outlet and Inlet Tanks: The inlet and outlet tanks help the radiator move coolant from the hot parts of your engine to the radiator.

Transmission cooler: Usually the vehicle uses the same coolant that the engine uses to cool the transmission . Transmission fluid moves through your engine through steel pipes, which are surrounded by coolant that conducts heat away from them. This coolant is also cooled within the radiator; as serious heat is generated through automatic transmission. Sometimes a separate radiator can be used to cool down your transmission fluid, but most often only a single radiator is used for both these functions.

Why is your radiator important?

A radiator is an essential part of your engine that prevents its overheating. If your vehicle’s radiator is damaged, it can cause severe problems in the engine. The most common cause of radiator malfunction is physical damage, which warrants a replacement of one or all of its components. The radiator can fail because of expired coolant or lacking coolant levels, which you can fix with a coolant flush .
