How to Change an A/C Compressor
The car air conditioner compressor is known as the heart of the air conditioning system. It is a pump that is driven by a belt and found fastened to the engine. The job of the auto air compressor is to compress and transfer coolant gas. The air conditioning system is broken down into two sides; a high pressure side and a low pressure side. The compressor has an intake side which draws in the coolant gas from an outlet on the evaporator, and it has a discharge side through which the coolant is compressed and sent through a condenser which transfers the heat from the inside of the cabin.

It is important to remove as much of the contaminated oil as possible. Lastly, the air conditioner hose assemblies. There are three different hoses that you should be careful and pay attention to.
