Have you ever experienced driving your Pontiac vehicle on a hot humid day and your car's air conditioning system is down? And you have no choice but to wipe the sweat on your forehead, while the other people riding with you have to fan themselves with their handkerchiefs or with a piece of cardboard. This is such a dreadful sight and you could have wished that you have checked your vehicle's air conditioning system before you go on for a ride. Air conditioning unit is not only of vital importance at home and offices; it also plays an important function in any type of vehicle. Just imagine riding your car on a summer day without AC on it or a defective one; or on a rainy day and you could not open your car's window. You would not want that to happen to you right? That is why it is important that you keep your vehicle's air conditioning system in good working condition.

A Pontiac vehicle is known to be one of the most comfortable vehicles that you can ride in. It is because of its loads of features, one of which is its air conditioning system that makes its interior really cool and relaxing especially during the summer season. An air conditioning system basically operates on the principles of evaporation and condensation. These principles are utilized in your Pontiac's air conditioning system by a series of components which include the AC compressor, AC condenser, receiver-drier, thermostatic expansion valve, evaporator, and refrigerant. Although the refrigerant is considered to be the life and blood of the air conditioning system, still it is important that all these components should all be working perfectly just like the Pontiac AC compressor.

The Pontiac AC compressor is the power unit of the Pontiac AC system. It is the part of the air conditioning system responsible to move the liquid refrigerant, which is a vital AC component, around in a pipe. It is powered by a drive belt which is connected to the Pontiac engine's crankshaft. It compresses the refrigerant vapor, heats it up and pumps it under high pressure to the condenser when the AC system is turned on. The AC Compressor should include two important components: the AC compressor clutch and the AC compressor drive ring. These two has different functions useful to the overall function of the AC compressor.

Because of the comfort that an air conditioning system brings, it should therefore be maintained at all times. If one of its components like the Pontiac Ac compressor is defective, you can get replacement parts here at Parts Train, where a variety of car parts and accessories is made available for you for easy access and convenience.
