(15) Remove the heater core cover from the hous-
ing assembly.
(16) Remove the coolant lines from the heater core.
(17) Remove the screws necessary to disassemble
the A/C-Heater housing assembly.
(18) Remove the evaporator coil from the A/C-
Heater housing (Fig. 3).
INSTALLATION
NOTE: When the evaporator coil is replaced, some
refrigerant oil will remain in the old evaporator. This
oil must be replaced before the system is operated.
(1) Install the evaporator coil in the A/C-Heater
housing (Fig. 4). Be certain all seals are replaced in
there original positions.
(2) Reassemble the A/C-Heater housing.
(3) Install the housing in the vehicle and install
the retaining bolts. Torque the bolts to 20 N´m (177
in. lbs.).
(4) Connect the electrical connectors on the A/C-
Heater housing.
(5) Install the defroster duct on the A/C-Heater
housing and secure at the body attachment point.
(6) Working from inside the engine compartment,
install the A/C-Heater housing drain tube and retain-
ing clip.

(7) Install the A/C-Heater housing retaining fas-
teners. Torque the fasteners to 20 N´m (177 in. lbs.).
(8) Install the heater core coolant supply hoses on
the heater core (Fig. 5).
(9) Install the expansion valve (Fig. 6), gasket and
retaining bolts. Torque the bolts to 11 N´m (97 in.
lbs.).
(10) Connect the electrical connector on the bottom
of the expansion valve (Fig. 6).
(11) Install the refrigerant lines and retaining bolt
(Fig. 6). Torque the bolt to 23 N´m (203 in. lbs.).
CAUTION: Be certain the refrigerant line sealing
O-rings are well lubricated and free of tears.
(12) Install the instrument panel. Refer to Group
8E, Instrument Panel and Systems for the procedure.
(13) Charge the refrigerant system.
(14) Fill the cooling system. Refer to Group 7,
Cooling System for the procedure.
(15) Connect the negative battery cable.

RESTRAINT SYSTEMS BEFORE ATTEMPTING ANY
STEERING WHEEL, STEERING COLUMN, ORINSTRUMENT PANEL COMPONENT DIAGNOSIS OR
SERVICE. FAILURE TO TAKE THE PROPER PRE-
CAUTIONS COULD RESULT IN ACCIDENTAL AIR-
BAG DEPLOYMENT AND POSSIBLE PERSONAL
INJURY.
WARNING: DO NOT OPEN THE RADIATOR DRAIN-
COCK OR DISCONNECT COOLANT HOSES WHEN
THE SYSTEM IS HOT AND UNDER PRESSURE.
SERIOUS BURNS FROM COOLANT CAN OCCUR.
(1) Disconnect the negative battery cable.
(2) Drain the cooling system. Refer to Group 7,
Cooling System for the procedure.
(3) Evacuate the refrigerant system.
(4) Remove the instrument panel. Refer to Group
8E, Instrument Panel and Systems for the procedure.
(5) Remove the refrigerant line retaining bolt from
the expansion valve (Fig. 7). Remove the refrigerant
lines from the expansion valve.
(6) Disconnect the electrical connector from the
bottom of the expansion valve (Fig. 7).
(7) Remove the expansion valve retaining bolts
and remove the valve from the vehicle.

FASTENER USAGE
WARNING: USE OF AN INCORRECT FASTENER
MAY RESULT IN COMPONENT DAMAGE OR PER-
SONAL INJURY.
Figure art, specifications and tightening torque ref-
erences in this manual are identified in metric and
SAE format.
During any maintenance or repair procedures, it is
important to salvage all fasteners (nuts, bolts, etc.)
for reassembly. If the fastener is not salvageable, a
fastener of equivalent specification must be use.
METRIC SYSTEM
The metric system is based on quantities of one,
ten, one hundred, one thousand and one million (Fig.
5).
The following chart will assist in converting metric
units to equivalent English and SAE units, or vise
versa.
