ACR 2000 recovers, recycles, evacuates and recharges A/C refrigerant quickly, accurately and The ACR 2000 has a built in A/C refrigerant identifier that will test for contamination, prior to The ACR 2000 also features automatic air purge, single pass recycling and an automatic oil drain. Refer to the J 43600 ACR 2000 manual for operation and setup instruction. See Special Tools. A/C Refrigerant System Oil Charge Replenishing If oil was removed from the A/C system during the recovery process or due to component FLUSHING Tools Required J 41447 Leak Detection Dye. See Special Tools. J 42220 Universal 12V Leak Detection Lamp. See Special Tools. J 43600 ACR 2000 Refrigerant Station. See Special Tools. J 45268 Flush Adapter Kit. See Special Tools. Flush Flushing is intended to remove the following: Contaminated PAG oil IMPORTANT: Flushing is not intended to remove metal from the A/C system.

Desiccant, following a desiccant bag failure Overcharge of PAG oil Refrigerant contamination 1. Recover the refrigerant. Refer to Refrigerant Recovery and Recharging. 2. Remove the orifice tube. Refer to Expansion (Orifice) Tube Replacement. 3. Connect the A/C lines with the orifice tube removed. 4. Remove the A/C compressor. Refer to Air Conditioning Compressor Replacement (LY2, LY5, LH6, L76, L92 and LMG) or Air Conditioning Compressor Replacement 5. Install J 45268 -3 to the A/C compressor hose assembly. See Special Tools. Fig. 4: View Of A/C Filter And Check Valve 6. Forward flow refrigerant flushing is recommended for contaminated refrigerant or PAG oil. Perform the following procedure: IMPORTANT: Warmer engine or ambient temperature decreases the refrigerant recovery time during the A/C flush procedure. IMPORTANT: The filter inside J 45268 -1 is serviceable. See Special Tools. Remove and discard the check valve from the

1. Service the filter with ACDelco P/N GF 470, before each flush. Connect J 45268 -1 flush filter to the suction port of the J 45268 -3 flush adapter. See 2. Connect the blue hose from the J 43600 to J 45268 -1 flush filter adapter. See Special Tools. 3. Connect the red hose from the J 43600 to J 45268 -3. See Special Tools. 7. Reverse flow refrigerant flushing is recommended for desiccant bag failure only. Perform the following procedure and replace the accumulator when the flush is complete: 1. Service the filter with ACDelco P/N GF 470, before each flush. Connect the J 45268-1 flush filter to the discharge port of J 45268 -3 flush adapter. 2. Connect the blue hose from J 43600 to J 45268 -1 flush filter adapter. See Special Tools. 3. Connect the red hose from J 43600 to the suction port of J 45268 -3. See Special Tools. 8. Flush the A/C system. Follow the instructions supplied with the J 43600 . See Special Tools. 9. Remove the J 45268 -3 from the A/C compressor hose assembly. See Special Tools. 10. Drain the PAG oil from the A/C compressor. Rotate the compressor input shaft to assist in draining the PAG oil from the compressor. 11. Add back the total system capacity of PAG oil to the A/C compressor. Refer to IMPORTANT: The filter inside the J 45268-1 is serviceable. Remove and discard the check valve from the filter. IMPORTANT: Close the valve on the external refrigerant tank, before starting the flush process. IMPORTANT: Flushing will remove all the PAG oil from the A/C system. The A/C system must be replenished with the correct amount

Refrigerant System Capacities. 12. Add one bottle of J 41447 directly to the A/C Compressor. See Special Tools. 13. Install the A/C compressor. Refer to Air Conditioning Compressor Replacement (LY2, LY5, LH6, L76, L92 and LMG) or Air Conditioning Compressor Replacement 14. Inspect the orifice tube for debris. Clean or replace as needed. 15. Install the orifice tube. Refer to Expansion (Orifice) Tube Replacement. 16. Evacuate and recharge the A/C system. Refer to Refrigerant Recovery and Recharging. 17. Leak test the fittings using the J 42220 . See Special Tools. COMPRESSOR OIL BALANCING Draining Procedure 1. Before draining oil, position the compressor verdically (clutch facing upwards) and let it sit for 1 minute. 2. Position the compressor horizontally, with the ports facing downward, rotate the clutch and shake the compressor in order to remove as much oil from the compressor as possible. 3. Drain the oil from both the suction and discharge ports of the removed compressor into a clean, graduated container. Rotate the compressor shaft to assist in draining the compressor. IMPORTANT: Flushing will remove the fluorescent leak detection dye from the A/C system. IMPORTANT: Drain and measure as much of the refrigerant oil as possible from the removed compressor.
