Flushing

Special Tools

•J 43600 ACR 2000 Air Conditioning Service Center
•J 45268 Flush Adapter Kit
•J 41447 R134A A/C Tracer Dye - Box of 24
•J 42220 Universal 12V Leak Detection Lamp

Note

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

Flushing is intended to remove the following:

•Contaminated polyalkylene glycol (PAG) oil
•Desiccant, following a desiccant bag failure
•Overcharge of PAG oil
•Refrigerant contamination
  1. Warmer engine or ambient temperature decreases the refrigerant recovery time during the A/C flush procedure.
  2. Remove the thermal expansion valve (TXV). Refer to Air Conditioning Evaporator Thermal Expansion Valve Replacement .
  3. Install the stud for the J 45268 kit onto the J 45268-115.
  4. Install the J 45268-115 in place of the TXV.
  5. Install the TXV mounting bolts and tighten to 7 N·m (62 lb in).
  6. Connect the evaporator line to the J 45268-115.
  7. Install the TXV block fitting nut. Tighten the bolts to 27 N·m (20 lb ft).
  8. Remove the A/C compressor. Refer to Air Conditioning Compressor Replacement .
  9. Install J 45268-10 to the A/C compressor hose assembly.
  10. Install the nut and bolt from the J 45268 kit to the J 45268-10 and compressor hose assembly. Tighten the bolts to 27 N·m (20 lb ft).
  11. Forward flow refrigerant flushing is recommended for contaminated refrigerant or PAG oil.
  12. Reverse flow refrigerant flush is recommended for desiccant bag failure. Replace the receiver dehydrator when the A/C flush is complete and perform the following procedure:
  13. Close the valve on the external refrigerant tank, before starting the flush process.
  14. Disconnect the red hose on the J 43600 from the J 45268-10.
  15. Disconnect the blue hose on the J 43600 from the J 45268-1.
  16. Remove J 45268-1 from the J 45268-10.
  17. Remove the J 45268-10 from the A/C compressor hose assembly.
  18. Flushing will remove all the PAG oil from the A/C system.
  19. If you will replace the A/C compressor after flushing the system, perform the following procedure:
  20. Install the A/C compressor. Refer to Air Conditioning Compressor Replacement .
  21. Remove J 45268-115.
  22. Inspect the TXV for debris. Clean or replace as needed.
  23. Install the TXV. Refer to Air Conditioning Evaporator Thermal Expansion Valve Replacement .
  24. Evacuate and recharge the A/C system. Refer to Refrigerant Recovery and Recharging .
  25. Leak test the fittings using J 42220 .
