1. Turn off the engine and allow it to cool down. This will help to reduce the pressure in the air conditioning system.
2. Locate the low-pressure service port on the air conditioning system. This is usually a Schrader valve located on the receiver-drier or accumulator.
3. Connect a refrigerant recovery machine to the low-pressure service port. This machine will help you to remove the excess refrigerant from the system.
4. Start the refrigerant recovery machine and allow it to run until the pressure in the system has been reduced to the recommended level. This may take several minutes.
5. Once the pressure has been reduced, stop the refrigerant recovery machine and disconnect it from the low-pressure service port.
6. Close the low-pressure service port.
7. Start the engine and allow it to run for a few minutes. This will help to circulate the refrigerant throughout the system and ensure that the pressure is correct.
_NOTE: Refrigerant is a hazardous material. Always follow the manufacturer's instructions when using a refrigerant recovery machine.
_If you are uncomfortable performing this procedure yourself, you may want to take your car to a professional to ensure it is handled safely._
