ACR2000 (GE-48800) A/C System Procedure

WARNING: This page is about a different car, the 2019 Chevrolet Malibu. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:

Flushing with the ACR 2000 is not intended to remove metal from the A/C system.

Flushing is intended to remove the following contaminants:

    NOTE:

    Warmer engine or ambient temperature decreases the refrigerant recovery time during the A/C flush procedure.

  1. Recover the refrigerant. Refrigerant Recovery and Recharging (R-1234yf) 
  2. Remove the air conditioning receiver and dehydrator. Receiver and Dehydrator Replacement 
  3. Remove the air conditioning refrigerant desiccant plug from the desiccant cartridge.
  4. Install the air conditioning refrigerant desiccant plug without the desiccant cartridge.

    Forward flow refrigerant flushing is recommended for contaminated refrigerant or POE oil.

  17. Perform the following procedure:
      NOTE:

      The filter inside the GE-45268-1 is serviceable. Remove and discard the check valve from the filter.

    1. Service the filter with ACDelco P/N GF 470, before each flush.

      Connect the GE-45268-1 flush filter to the suction port of the GE-45268-4 flush adapter.

    2. Connect the blue hose from the GE-48800  ACR 2000 Air Conditioning Service Center to the J 45268-1 flush filter adapter.
    3. Connect the red hose from the GE-48800  ACR 2000 Air Conditioning Service Center to the GE-45268-5 flush adapter.
  18. Reverse flow refrigerant flushing is recommended for desiccant cartridge failure.
      NOTE:

      The filter inside the J 45268-1 is serviceable. Remove and discard the check valve from the filter.

    1. Service the filter with AC P/N GF 470, before each flush. Connect the J 45268-1 flush filter to the discharge port of the GE-45268-5 flush adapter.
    2. Connect the blue hose from the GE-48800  ACR 2000 Air Conditioning Service Center to the J 45268-1 flush filter adapter.
    3. Connect the red hose from the GE-48800  ACR 2000 Air Conditioning Service Center to the suction port of the GE-45268-4 flush adapter.
    19. NOTE:

    Close the valve on the external refrigerant tank, before starting the flush process.

  19. Flush the front A/C system. Follow the instructions supplied with the GE-48800  ACR 2000 Air Conditioning Service Center.
    20. NOTE:

    Close the valve on the external refrigerant tank, before starting the flush process.

  20. Flush the A/C system. Follow the instructions supplied with the GE-48800  ACR 2000 Air Conditioning Service Center
  21. Remove the GE-45268-4 from the A/C compressor suction hose.
  22. Remove the GE-45268-5 from the A/C compressor discharge hose.
    23. NOTE:

    Flushing will remove all the POE oil from the A/C system.

    The A/C system must be replenished with the correct amount of POE oil.

  23. If the removed A/C compressor is being reinstalled, perform the following procedure:
  24. If you will replace the A/C compressor after flushing the system, perform the following procedure:
    1. Refer to the Approximate Fluid Capacities 
    2. DO NOT drain the new POE oil from the compressor.
    3. Deduct the amount of POE oil shipped with the service compressor from the amount of POE oil listed in the capacities table. Approximate Fluid Capacities 
    4. Add the calculated amount to the compressor, as needed.
  25. Install the air conditioning and drive motor battery cooling compressor. Air Conditioning with Motor Compressor Replacement (LKN) 
    26. NOTE:

    Flushing will remove the fluorescent leak detection dye from the A/C system.

    NOTE:

    The air conditioning refrigerant desiccant is manufactured with POE fluorescent leak detection dye wafer inside.

  26. Replace the air conditioning receiver and dehydrator. Receiver and Dehydrator Replacement 
  27. Remove A/C evaporator TXV tube from both GE-45268-115.
  28. Remove A/C evaporator tube from both GE-45268-115.
