What is the purpose of a radiator in a car and how do I keep it in working well?

My car’s radiator – why do I have one, how does it work and do I need to do anything to maintain it? The purpose of a radiator in a car explained and handy tips to keep it in good order.

Why Do I Need A Radiator In My Car?

All radiators, in vehicles or other applications, do the same job. They dissipate heat from the liquid flowing through them into the atmosphere. The purpose of a radiator in a car is to lower the temperature of the hot liquid coming from your engine & return it cooled. This then reduces the heat that is produced through the normal running of the motor. The cooling is achieved by air flowing over the large surface area of the radiator itself.

Airflow and why it is so important for my radiator

If for some reason air is prevented from flowing over the fins of the radiator, it cannot perform its cooling function. When driving forward a car creates it’s own airflow but when stationary or moving slowly this has to be created by using a radiator fan. Of course, if the fan is not working you may experience an overheating car, particularly if you are driving at low speed in traffic. Sometimes the radiator could be blocked up with dirt and grime which again will not allow for proper airflow.

Coolant In The Radiator

The fluid that flows through your radiator (called coolant) is the lifeblood of the cooling system. It is a precise mix of water and an additive (antifreeze) that is recommended for use in your vehicle. The level of coolant must be checked regularly and if liquid is being lost from the system there is probably a leak somewhere. If a leak exists an ADRAD radiator repair expert can locate and repair it before it becomes a costly issue. Coolant degrades with use and periodically needs to be replaced. Your vehicle also needs a radiator flush about once a year to get rid of deposits that have built up through normal operation. Leak detection, radiator leak repair and regular maintenance of your radiator & radiator hoses are standard services offered by all ADRAD agents throughout New Zealand.

Radiator Maintenance In Cars

To avoid the troublesome issue of your vehicle overheating radiators need to be maintained on a regular basis. Some of this can be done by the vehicle owner, for example, checking on the radiator coolant level or inspecting the radiator cap. This website has some great radiator maintenance tips for you.

Most other procedures like radiator leak detection, cooling system flush and radiator repairs are best handled by an expert at an ADRAD radiator repair shop.

In addition to radiator parts, radiator repairs & radiator maintenance we also sell aftermarket radiators for all types of cars. Contact your nearest agent for quality radiator service or to enquire about radiator flush cost or even radiator replacement cost. All our work, parts and products are covered by a 2 year, nation-wide warranty support.

How does a car radiator work?

How a radiator works is through simple heat transference. Basically, it cools the engine down by taking heat out of the engine, cooling it down with air. Liquid coolant circulates around the metal of the engine, this liquid absorbs the heat from the engine and then is pumped from the engine and into the radiator where it passes through thin pipes. These pipes are exposed to air. Often there is a fan which pushes air past the radiator, helping the coolant inside to cool down faster.

How does a radiator work? The fins.

The fins are an important part of the radiator assembly. They make sure that the most surface area is exposed to the air as possible – a thin piece of metal will cool a lot quicker than a thick piece. This is why if the fins are damaged the radiator will not work as efficiently.
