GENERAL PROCEDURES
Air Conditioning (A/C) System Flushing
WARNING: Use extreme care and observe all safety and service precautions related to the
use of refrigerants.
WARNING: Due to refrigerant hazards, always wear safety goggles and non- penetrable
gloves when working on or flushing A/C systems.
CAUTION: An A/C refrigerant analyzer must be used before the recovery of any vehicle's
A/C refrigerant. Failure to do so puts the shop's bulk refrigerant at risk of contamination. If the
vehicle's A/C refrigerant is contaminated, refer the customer to the service facility that carried
out the last A/C service. If the customer wishes to pay the additional cost, use the A/C recovery
equipment that is designated for recovering contaminated A/C refrigerant. All contaminated
A/C refrigerant must be disposed of as hazardous waste. For all equipment, follow the
equipment manufacturer's procedures and instructions.
CAUTION: Suction accumulator/drier, muffler, hoses, thermal expansion valve, and fixed
orifice tube should be removed when flushing the A/C system. Internal plumbing of these
devices makes it impossible to correctly remove any residual- flushing agent. Except for the
hoses, these components are typically discarded after A/C system contamination. Hoses can
normally be reused unless they are clogged with foreign material. The 3.785 liters (1 gallon) of
A/C Systems Flushing Solvent F4AZ-19579- A and FL1-A filter used in A/C Flush and Purge
Machine 219- 00022 are intended for use on one vehicle only. They may be used to flush both
the A/C condenser core and the A/C evaporator core on an individual vehicle, but under no
circumstances should they be used on more than one vehicle.
1. NOTE: Prior to using the A/C Flush and Purge Machine 219- 00022 for the first time, review the
operating instructions.
NOTE: Only the A/C Flush and Purge Machine kit 219- 00023, which includes A/C Flush and
Purge Machine 219- 00022, A/C Flush and Purge Fitting Kit 219- 00024, and the Ford Part
number F4AZ-19579- A A/C Systems Flushing Solvent, is approved for use on Ford vehicles. No
other flushing device or solvent is approved for flushing heat exchangers. Use of any other
flusher or solvent may cause damage to the A/C system and the flushing unit.

FORD MUSTANG 2003 Workshop Manual Ford Motor Company has approved a procedure to provide technicians with a non-
CFC method
of flushing contaminated A/C system heat exchangers, A/C evaporator core, and A/C
condenser core. The proced

Ford Motor Company has approved a procedure to provide technicians with a non-
CFC method
of flushing contaminated A/C system heat exchangers, A/C evaporator core, and A/C
condenser core. The procedure allows the specific 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 or desiccant failure within the suction accumulator/drier
and gummy residue that can 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 Flush and
Purge Machine 219- 00022 to:
z 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.
z 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 evaporate any remaining
flush solvent from the heat exchanger.
2. Discharge the A/C system. Observe all safety precautions. For additional information, refer to the procedure in this section.
3. Disconnect the refrigerant lines from the heat exchanger(s) to be flushed.
4. Connect the A/C Flush and Purge Machine 219- 00022 and A/C Flush and Purge Fitting Kit 219-
00024 to the heat exchanger to be flushed. Do not flush through the A/C evaporator core orifice,
mufflers or hoses. Internal plumbing and material make- up of these components make it
impossible to correctly remove foreign material or residual flushing solvent.
5. Use 3.785 liters (one gallon) of A/C Systems Flushing Solvent part number F4AZ-19579- A 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 the 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 evaporate all residual 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 the used flush
solvent and filter in accordance with local, state and federal emissions.
8. NOTE: A/C system filtering as described in this section is optional if system flushing is carried
out. However, the filter kit use is recommended after flushing if the A/C system contamination is
extensive.
Install a new A/C evaporator core orifice in any vehicle being serviced for A/C compressor or
desiccant failure.
9. Install new refrigerant hoses if clogged with foreign material.
10. Reconnect the heat exchanger being serviced.
11. Add additional refrigerant oil as required. For additional information, refer to the procedure in this section.
12. Evacuate, leak test and charge the A/C system. For additional information, refer to the procedure in this section.
13. Check the system for normal operation. Klj . 2 ba
