High pressure vapor.
Ac compressor
Is compressor running? If refrigerant charge is low it will not
No you don't have to change the A/C Compressor.
The AC compressor on a 92 Acura Legend is removed by vacuuming out the refrigerant, disconnecting the wiring, and unscrewing the AC hose. The compressor can then be unbolted and pulled from the engine.
It compresses the refrigerant (probably r134a) and pushes it through the ac system.
You will have to replace the refrigerant, but not the engine coolant.
AC compressors will cycle like that when there is insufficient refrigerant.
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.
You are low on refrigerant, google R134a...
When you turn on the AC, check to see if the compressor is running. If the compressor clutch is not engaging, it might be as simple as low refrigerant level. Automobile AC is not like a home AC. Since the compressor cannot be sealed, the seal always leaks a little and you need to occasionally add a little refrigerant.
Cycles refrigerant through the system and changes the state of the refrigerant from a low pressure vapor to a high pressure vapor.
this vehicle uses a variable ac compressor that is always on, your probably low on refrigerant
