Air Conditioning (A/C) System Flushing

1. This procedure allows the specified components to be cleaned and flushed while installed in their normal in-vehicle location. The types of contamination flushed include particle matter that results from A/C compressor and/or desiccant failure within the suction accumulator/drier and gummy residue that may form when refrigerant oil is overheated during A/C compressor seizure. The flushing process is a two-step procedure that involves the use of an A/C Flusher to: Circulate the flushing solvent through the heat exchanger in the reverse direction of normal refrigerant flow (back-flushing). Particulate matter picked up during flushing is filtered from the returning solvent before the solvent is returned to the reservoir for continued circulation. Remove the flushing solvent from the heat exchanger. In this step of the procedure, pressurized air 621-862 kPa (90-125 psi) is used to push and/or evaporate any remaining flush solvent from the heat exchanger.
2. Reclaim the refrigerant. For additional information, refer to.
3. Disconnect refrigerant lines from the heat exchanger(s) to be flushed. For additional information, refer to «AIR CONDITIONING»(ref-199554) .
4. Connect A/C flusher and A/C flusher fitting kit to the heat exchanger to be flushed. Do not flush through the A/C evaporator core orifice, mufflers or lines. Internal plumbing and material make-up of these components make it impossible to correctly remove debris and/or residual flushing solvent.
5. Use flushing solvent to flush the heat exchanger for a minimum of 15 minutes. The flush solvent may be used for one or both heat exchangers in the A/C system. However, the flush solvent is intended for one vehicle only. The filter used on the flushing unit is also intended for use on one vehicle only.
6. Flush component for a minimum of 15 minutes.
7. Apply 621-862 kPa (90-125 psi) pressurized air to the component for a minimum of 30 minutes. The 30 minute purge time is required to force and/or evaporate all residual flush solvent from the A/C system component. Failure to successfully remove all residual solvent within the component can result in system damage when reconnected and operated. Dispose of used flush solvent and filter in accordance with local, state and federal ordinances.
8. Install new suction accumulator/drier and A/C evaporator core orifice on any vehicle being repaired for A/C compressor or desiccant failure.
9. Install new refrigerant lines if clogged with debris.
10. Reconnect the heat exchanger being flushed.
11. Add additional refrigerant oil as required. For additional information, refer to.
12. Evacuate, charge and leak test A/C system.
13. Check A/C system for correct operation.
