Cooling and Heating Parts. 


Air Conditioning 

Air conditioning systems, or A/C systems as they are sometimes known, contribute greatly to the modern day driving experience and are especially important when it comes to keeping occupants comfortable during hot weather conditions. Few things are able to spoil a journey quite like poor temperature control and for this reason, it is essential to regularly check on your A/C system's individual components.

The main purpose of an air conditioning system is to take the air in a car, reduce its moisture content - or humidity - and cool it down to the required temperature. This then results in a more comfortable temperature within the car.

Air conditioning systems are made up of numerous parts, including compressors, expansion valves, condensers and evaporators. If any of these components break or malfunction, the A/C system will suffer and so will your driving experience. Fortunately, we stock a wide variety of air conditioning parts (Compressor / Parts , Condenser, Controls/Regulation, Dryer, Hoses/Pipes, Sensors, Switch, Valves, Vaporizer), for a large number of different vehicles. All of our parts come from quality manufacturers, ensuring your air con system gets back to full health quickly.


Cooling Systems

Because a car engine will produce a lot of heat as it runs, there is a need for it to be continuously cooled and can contain various part from Control Unit, Hoses/ Pipes/ Flanges, Radiator Fan, Sender Unit, coolant temperature, Thermostat/ Gasket, Water Pump/ Gasket etc it only take one of these parts for your engine to  overheat. The most common way that this is done is by a coolant liquid circulating around. Some engines use an air flow system rather than water. With an engine that is cooled by water, the block and cylinder head are connected by a 'coolant channels' that are routed through them. All of the channels meet in one outlet, which is situated at the top of the cylinder head.

There is a pump that circulates the coolant, and this gets its power via a belt operated from the crankshaft. The coolant liquid is pumped out of the engine into the radiator system, which acts as a heat exchanger. To get the water from to radiator into the engine, rubber hoses are used. The standard temperature that the engine runs at is a little below boiling. To stop the boiling temperature being reached, the systems pressure is increased, which has an effect of raising the boiling point.

Modern cars have a sealed cooling system, which includes an overflow tank. For optimum effectiveness, the radiator requires a constant flow of cold air. This is provided by the fan. An air-cooled engine works on the same principle, but the cylinder head and the block have 'air' fins on the outside.



A good heating system will insulate your vehicle, providing you and your family with the warmth you need. In every heating system there will be a heater motor, which is usually found behind the dashboard. This is responsible for blowing air across a heater core or evaporator, and the air is processed by a number of vents to direct it into a certain position. Most heaters are powered by an electrical circuit to control fan speeds.

Heaters will need to be replaced over time, especially if they start to malfunction or don't provide the right amount of air. We have a number of high quality heaters for your vehicle, and we will be able to recommend the best product for your lifestyle and budget.
