It compresses the refrigerant (probably r134a) and pushes it through the ac system.
You have a system performance test done on your AC system.
The ac compressorThe ac compressor
Just disconnect the plug at the compressor. The A/C compressor will no longer function.
An AC compressor is part of an air conditioner which may be used in a car's AC system. The compressor is used to change the pressure between the AC's compartments in order to help condense the refrigerant gas back into a liquid.
The amount of oil charge required for an automotive AC system is specific to the car. There is not standard amount for all cars.
They can get noisy and leak oil. You want to replace a noisy ac compressor before it fills the system with metal trash.
The ac compressor may be on its way out and binding. Disconnect it before it fills the ac system with trash.
ac compressor was working fine before one of the seals blew and i lost gas.Pulled a vacuum on the system and put in new gas.Now my compressor clutch is no longer working.Checked the relay switch and it is fine.Not quite sure what the compressor diode does so not sure if that's the problem or if for some reason my compressor went bad all of a sudden?
The AC is a "system", not a single component, and as such, there are parts of the AC system in several areas of the vehicle. The AC compressor is on the engine and receives it's power from the serpentine belt. The AC clutch is on the compressor, enabling the compressor to be disengaged from the serpentine belt when the compressor is not needed. The AC evaporator is a coil that 's inside the heater box, under the dashboard. The AC condenser is in front of the engine radiator. The AC receiver/dryer is under the hood, attached to the firewall. And the AC refrigerant hoses connect everything together.
If there is metal chips and trash from the old compressor in the system, yes you need to flush the system. Any trash left in the system will shorten the life of the new pump.
Shops use a freon recovery system that contains the freon while the system gets worked on. The system has to be cleaned and vaccumed properly to remove trash and moisture or it will fail again or even not function properly.
