Basic Car Parts and Their Specific Functions and Purposes

AC compressor is a car part located in the engine compartment. This is found on one side and attached to serpentine drive belt. Freon is cycled through in the AC compressor to provide your vehicle with cool air.

You will be able to tell if there is damage in the compressor if there is no cold air coming through air vents. The compressor may also produce bothersome and loud noises during operation.


Alternator is a device that generates electricity, the alternator converts mechanical energy into electrical energy in alternating current form. This is used for supplying power to the electrical system of your car together with the battery. The battery is also recharged by the alternator with the use of mechanical energy produced through the motion of the car parts
