GENERAL PROCEDURES (

)
1. NOTE:
Prior to using A/C Flusher for the first
time, review its operating instructions.
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)
has approved. 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 desiccant failure
within the suction accumulator 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 6.2-8.6 bar
(621-862 kPa) is used to push and
evaporate any remaining flush solvent
from the heat exchanger.
2. NOTE:
Only A/C Flushing Kit, which includes
A/C Flusher, A/C Flusher Fitting Kit and Ford
A/C System 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.
A/C flusher components consist of:
• Valve No. 1 (Part of 014-00991)
• Valve No. 2 (Part of 014-00991)
• Flush Quick Coupler (Part of 014-00991)
• Moisture Trap (Part of 014-00991)
• Air Purge Valve (Part of 014-00991)
3. Reclaim the refrigerant. For additional
