INSTALLATION

For installation, reverse the above procedure.

EVAPORATOR PROBE

REMOVAL

(1) Disconnect battery.
(2) Remove right under panel silencer/duct.
(3) Disconnect wiring connector for evaporator

probe (Fig. 39).

(4) Using a flat blade pry tool, pull back on the

locking tab. Twist the access plate clockwise one-
quarter turn and remove plate (Fig. 40).

REMOVAL AND INSTALLATION (Continued)

INSTALLATION

(1) Install new probe into the evaporator. The

new probe must not go into the same hole (in
the evaporator core) that the old probe was
removed. The evaporator is manufactured with
three holes for probe insertion. Insert the probe in
the uppermost hole.

(2) Install evaporator probe access panel.
(3) Connect probe wiring harness.
(4) Reconnect battery.

WARNING: AVOID BREATHING A/C REFRIGERANT
AND LUBRICANT VAPOR OR MIST. EXPOSURE MAY
IRRITATE EYES, NOSE AND THROAT. USE ONLY
APPROVED SERVICE EQUIPMENT MEETING SAE
REQUIREMENTS TO DISCHARGE R-134a SYSTEM. IF
ACCIDENTAL SYSTEM DISCHARGE OCCURS, VEN-
TILATE WORK AREA BEFORE RESUMING SERVICE.

R-134a SERVICE EQUIPMENT OR VEHICLE A/C

SYSTEM SHOULD NOT BE PRESSURE TESTED OR
LEAK TESTED WITH COMPRESSED AIR. SOME
MIXTURES OF AIR/R-134a HAVE BEEN SHOWN TO
BE COMBUSTIBLE AT ELEVATED PRESSURES.
THESE MIXTURES ARE POTENTIALLY DANGER-
OUS AND MAY RESULT IN FIRE OR EXPLOSION
CAUSING INJURY OR PROPERTY DAMAGE.

REMOVAL AND INSTALLATION (Continued)

REMOVAL

(1) Remove refrigerant from the A/C system using

a refrigerant recovery machine.

(2) Disconnect clips from expansion valve lines

(Fig. 42) and (Fig. 43).

(3) Use special tool kit 7193 to disconnect quick

connectors on expansion valve (Fig. 44) and (Fig. 45).

(4) Remove lines at expansion valve (Fig. 46).
(5) Remove two retaining bolts from expansion

valve (Fig. 47).

(6) Remove expansion valve (Fig. 48).
(7) Remove expansion valve gasket.

INSTALLATION

CAUTION: Always

install

a

new

gasket

when

replacing expansion valve.

For installation, reverse the above procedures.

Tighten new expansion valve to 11 N·m (100 in. lbs.).

FILTER/DRIER

The filter/drier is a receiver for reserve refrigerant.

It also has a desiccant bag and a filter. This is used
to absorb moisture and filter the refrigerant as it
passes through the filter/drier.

The filter/drier is located left of the coolant bottle

(Fig. 49). The A/C refrigerant must be removed from
the system before removing the filter/drier. Always
use a refrigerant recovery machine.

Replace the filter/drier if an A/C system is left open

for an extended period of time.

REMOVAL AND INSTALLATION (Continued)

REMOVAL

(1) Remove refrigerant from A/C system using a

refrigerant recovery machine.

(2) Remove liquid line at filter/drier from con-

denser (Fig. 50).

(3) Remove liquid line at filter/drier from expan-

sion valve (Fig. 51).

(4) Remove filter/drier bracket bolt at base of fil-

ter/drier (Fig. 52).

(5) Cap liquid line and condenser threaded fitting

while system is open to prevent moisture from enter-
ing system.

INSTALLATION

CAUTION: When installing new filter/drier do not
leave open to atmosphere for a long period of time.

The filter/drier contains moisture absorbing materi-
als which will absorb moisture in the atmosphere.

For installation, reverse the above procedures.

HEATER CORE

The heater core is serviceable inside the vehicle.

However, if the core has leaked a significant amount
of coolant, the A/C housing must be removed. The
housing should be disassembled and cleaned thor-
oughly before heater core replacement. If housing
removal is necessary, refer to Heater-A/C Housing,
Removal and Installation in this section.

REMOVAL

(1) Disconnect battery negative remote cable.
(2) Remove radio/control module bezel (Fig. 27).
