GENERAL PROCEDURES (

4. Disconnect refrigerant lines from the heat
exchanger(s) to be flushed. For additional
information,
5. 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
properly remove debris and residual
flushing solvent.
6. Use Ford A/C 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.
7. Flush component for a minimum of 15
minutes.
8. Apply 6.2-8.6 bar (621-862 kPa)
pressurised air to the component for a
minimum of 30 minutes. The 30-minute
purge time is required to force and
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.
9. NOTE:
A/C system filtering as described in
this section is optional if system flushing is
performed. However, filter kit use is
recommended after flushing if A/C system
contamination is extensive.
Install new suction accumulator and A/C
evaporator core orifice on any vehicle being
repaired for A/C compressor or desiccant
failure.
10. Install new refrigerant lines if clogged with
debris.
11. Reconnect the heat exchanger being
flushed.
