What does a car radiator do?

All You Need to Know About Car Radiators

Lets go from the very top with an explanation about what a car radiator does! Car radiators are designed to cool down the coolant liquid that is pumped through your engine, so that it can continually be used to keep engine temperature down.  Working as a heat exchanger, radiators are mainly used for cooling down combustion engines.

Most engines create a large amount of heat, namely because they are powered by exceedingly small minute explosions. With an aim to cease overheating, the coolant in your engine takes heat away from the engine block to the radiator, which is designed to blow air across it, ready to be reused.

What are the main parts of a car radiator called?

 

With over 30 years of experience in vehicle radiator repair and replacement, we know that unlike many vehicle parts, and dependent on the issue, the radiator can often be repaired. Whilst the majority of modern and mass marketed vehicles will more than likely need their radiator replacing, classic or heavy-duty vehicles will need repair. We have included some of the internal parts belonging to a car radiator, depending upon the vehicle they may contain non typical components too.

Radiator Core

The radiator core is the largest part of the radiator, made of metal and consists of tubes and fins. Its primary purpose is to provide the engine coolant with a way to cool down, transferring heat into the air.

Pressure Cap

The pressure cap creates pressure within your radiator, allowing the surrounding coolant to become more hotter, which in turn makes the cooling system much more efficient.

Where is the radiator located in a car?

In most cases you will find the radiator under the front bonnet, unless you own a vehicle with the engine in the back. You will find the radiator next to the engine, as its main task is to cool it and the closer it is the more efficient it will be.

 

Do all cars have radiators?

Most cars including modern cars, contain internal combustion engines, which create a lot of heat from combustion. The heat that is produced still needs to be cooled to avoid internal damage of engine parts, so will need a radiator equipped. At first glance under the bonnet of newer cars can give the impression of not having a radiator, but this is due to the component being hidden.

 

Why are car radiators painted black?  

Most car radiators are painted black, this is due to it being the most efficient colour for heat radiation. It is the same idea as being hotter whilst in the sun wearing a black T-shirt, compared to wearing a white T-shirt.

 

Do electric cars have radiators?

There are numerous types of electric cars with differing engine setups, the best answer for this question is, some do! Radiators in electric cars are more than often used to cool down components such as batteries. Electric motors in these types of cars predominantly do not generate enough heat to warrant a dedicated radiator.
