24 - 34 PLUMBING
A/C CONDENSER (Continued)
(10) Remove the condenser (with auxiliary trans-
mission cooler attached) from the vehicle.
(11) Cut the auxiliary transmission cooler retain-
ing straps.
NOTE: The new condenser will include new retain-
ing straps for the auxiliary transmission cooler
attachment to new condenser assembly.
CAUTION: Avoid bending or breaking condenser
inlet tube when lifting radiator/condenser assembly
from the vehicle.
INSTALLATION
WARNING: REVIEW THE WARNINGS IN THE FRONT
OF THIS SECTION BEFORE PERFORMING THE
FOLLOWING OPERATION. (Refer to 24 - HEATING &
AIR CONDITIONING/PLUMBING - WARNING)
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 (Whenever possi-
ble).
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.
(1) Install the auxiliary transmission cooler in the
same position on the condenser with new retaining
straps.
(2) Install the condenser in the vehicle.
(3) Install the two screws retaining the condenser
to the radiator. Tighten the screws to 10.5 N·m (95
in. lbs.).
NOTE: Always install NEW O-rings and lubricate
with refrigerant oil.
(4) Connect the liquid line to the condenser inlet.
Tighten the retaining nut to 23 N·m (17 ft. lbs.).
(5) Connect the discharge line to the condenser
outlet. Tighten the retaining nut to 23 N·m (17 ft.
lbs.).
(6) Install the retainer bracket and screw for the
auxiliary transmission cooler lines.
(7) Connect the auxiliary transmission cooler hose
fittings.
(8) Install the upper radiator core support(Refer to
7 - COOLING/ENGINE/RADIATOR - INSTALLA-
TION).
(9) Connect the negative battery cable remote ter-
minal to the remote battery post.
(10) Evacuate the refrigerant system. (Refer to 24
- HEATING & AIR CONDITIONING/PLUMBING -
STANDARD PROCEDURE - REFRIGERANT SYS-
TEM EVACUATE)
(11) Charge the refrigerant system. (Refer to 24 -
HEATING & AIR CONDITIONING/PLUMBING -

TEM CHARGE)

REMOVAL
WARNING: REVIEW THE WARNINGS IN THE FRONT
OF THIS SECTION BEFORE PERFORMING THE
FOLLOWING OPERATION. (Refer to 24 - HEATING &
AIR CONDITIONING/PLUMBING - WARNING)
(1) Open the hood and disconnect the negative bat-
tery cable remote terminal from the remote battery
post.
(2) Recover the refrigerant from the system. (Refer
to 24 - HEATING & AIR CONDITIONING/PLUMB-
ING - STANDARD PROCEDURE -REFRIGERANT
RECOVERY)
(3) Disconnect the a/c pressure transducer wire
harness (Fig. 7) and (Fig. 8).
(4) Remove the a/c pressure transducer. (Refer to
24 - HEATING & AIR CONDITIONING/CONTROLS/
A/C PRESSURE TRANSDUCER - REMOVAL)
(5) Disconnect the discharge line at the compressor
using an M10 Hex wrench for 2.7L, and a 6 mm
allen wrench for 3.2/3.5L.
CAUTION: Cap all lines that are not being replaced
and cap the expansion valve tubes.
(6) Disconnect the discharge line at the A/C con-
denser using an M10 Hex wrench.
