A/C COMPRESSOR (Continued)
(6) Connect the discharge line fitting to the com-
pressor discharge port.
(7) Install the bolt that secures the discharge line
fitting to the top of the compressor. Tighten the bolt
to 23 N·m (17 ft. lbs.).
(8) Remove plugs or tape from the suction line fit-
ting and the compressor suction port.
(9) Lubricate a new rubber o-ring seal with clean
refrigerant oil and install the seal onto the suction
line fitting.
(10) Connect the suction line fitting to the com-
pressor suction port.
(11) Install the bolt that secures the suction line
fitting to the top of the compressor. Tighten the bolt
to 23 N·m (17 ft. lbs.).
(12) Install the accessory drive belt (Refer to 7 -
COOLING/ACCESSORY DRIVE/DRIVE BELTS -
INSTALLATION).
(13) Reconnect the negative battery cable.
(14) Evacuate the refrigerant system (Refer to 24 -
HEATING & AIR CONDITIONING/PLUMBING -
STANDARD PROCEDURE - REFRIGERANT SYS-
TEM EVACUATE).
(15) Charge the refrigerant system (Refer to 24 -
HEATING & AIR CONDITIONING/PLUMBING -
STANDARD PROCEDURE - REFRIGERANT SYS-
TEM CHARGE).
A/C CONDENSER
DESCRIPTION
The condenser is located in the air flow in front of
the engine cooling radiator. The condenser is a heat
exchanger that allows the high-pressure refrigerant
gas being discharged by the compressor to give up its
heat to the air passing over the condenser fins.
OPERATION
When the refrigerant gas gives up its heat, it con-
denses. When the refrigerant leaves the condenser, it
has become a high-pressure liquid refrigerant. The
volume of air flowing over the condenser fins is crit-
ical to the proper cooling performance of the air con-
ditioning system. Therefore, it is important that
there are no objects placed in front of the radiator
grille openings in the front of the vehicle or foreign
material on the condenser fins that might obstruct
proper air flow. Also, any factory-installed air seals or
shrouds must be properly reinstalled following radia-
tor or condenser service.
The condenser cannot be repaired and, if faulty or
damaged, it must be replaced.
REMOVAL
WARNING: REVIEW THE WARNINGS AND CAU-
TIONS IN THE FRONT OF THIS SECTION BEFORE
PERFORMING THE FOLLOWING OPERATION (Refer
to 24 - HEATING & AIR CONDITIONING/PLUMBING -
WARNING) and (Refer to 24 - HEATING & AIR CON-
DITIONING/PLUMBING - CAUTION).
(1) Disconnect and isolate the battery negative
cable.
(2) Recover the refrigerant from the refrigerant
system (Refer to 24 - HEATING & AIR CONDITION-
ING/PLUMBING - STANDARD PROCEDURE -
REFRIGERANT RECOVERY).
(3) Remove the front fascia.
(4) Remove the grille (Refer to 23 - BODY/EXTE-
RIOR/GRILLE - REMOVAL).
(5) Remove the headlamps from their mounts.
(6) Remove the radiator crossmember (Refer to 23
- BODY/EXTERIOR/RADIATOR CROSSMEMBER -
REMOVAL).
(7) Disconnect the liquid line fitting from the con-
denser outlet port (Fig. 3).
(8) Remove the seal from the liquid line fitting and
discard.
(9) Install plug in, or tape over the opened liquid
line fitting and the condenser outlet port.
(10) Disconnect the discharge line fitting from the
condenser inlet port.
(11) Remove the seal from the discharge line fit-
ting and discard.
(12) Install plug in, or tape over the opened dis-
charge line fitting and the condenser inlet port.
(13) Disconnect the wire harness connector from
the auxiliary fan.
(14) Remove the auxiliary fan and upper bracket
assembly.
(15) Remove the auxiliary fan lower bracket
retainers and bracket.
(16) Remove the four condenser retaining screws.
(17) Carefully remove the condenser from the vehi-
cle.
INSTALLATION
NOTE: If the condenser is being replaced, add 30
milliliters (1 fluid ounce) of refrigerant oil to the
refrigerant system. Use only refrigerant oil of the
type recommended for the compressor in the vehi-
cle.
(1) Carefully position the condenser in the vehicle.
(2) Install the four condenser retaining screws.
Tighten the screws to 2 N·m (17 in. lbs.).
