SERVICE. FAILURE TO TAKE THE PROPER PRE-
CAUTIONS COULD RESULT IN ACCIDENTAL AIR-
BAG DEPLOYMENT AND POSSIBLE PERSONAL
INJURY.
(1) Remove and disassemble the heater-A/C hous-
ing. See Heater-A/C Housing in this group for the
procedures.
(2) Lift the heater core out of the lower half of the
heater-A/C housing (Fig. 48).
(3) Reverse the removal procedures to install. Be
certain that the heater core foam insulator is rein-
stalled.
LIQUID LINE
Any kinks or sharp bends in the refrigerant plumb-
ing will reduce the capacity of the entire air condi-
tioning system. Kinks and sharp bends reduce the
flow of refrigerant in the system. A good rule for the
flexible hose refrigerant lines is to keep the radius of
all bends at least ten times the diameter of the hose.
In addition, the flexible hose refrigerant lines should
be routed so they are at least 80 millimeters (3
inches) from the exhaust manifold.
High pressures are produced in the refrigerant sys-
tem when the air conditioning compressor is operat-
ing. Extreme care must be exercised to make sure
that each of the refrigerant system connections is
pressure-tight and leak free. It is a good practice to
inspect all flexible hose refrigerant lines at least once
a year to make sure they are in good condition and
properly routed.
WARNING: REVIEW THE WARNINGS AND CAU-
TIONS IN THE FRONT OF THIS GROUP BEFORE
PERFORMING THE FOLLOWING OPERATION.
REMOVAL
(1) Disconnect and isolate the battery negative
cable.
(2) Recover the refrigerant from the refrigerant
system. See Refrigerant Recovery in this group for
the procedures.
(3) Disconnect the liquid line refrigerant line cou-
plers at the evaporator inlet and the condenser outlet
(Fig. 49). See Refrigerant Line Coupler in this group
for the procedures. Install plugs in, or tape over all of
the opened refrigerant line fittings.
(4) Remove the liquid line from the vehicle.
INSTALLATION
(1) Remove the tape or plugs from the refrigerant
line fittings on the liquid line, the evaporator inlet
and the condenser outlet. Connect the liquid line to
the evaporator inlet and condenser outlet refrigerant
line couplers. See Refrigerant Line Coupler in this
group for the procedures.
(2) Connect the battery negative cable.
