LIQUID LINE (Continued)
(5) Disconnect receiver/drier bracket fastener and
separate the bracket from the strut panel (there are
two hidden plastic fasteners to pry out).
(6) Disconnect the liquid line fastener at the con-
denser (M13 Hex).
NOTE: The radiator upper crossmember must be
removed to access the liquid line fastener. Refer to
Body for the procedures.
(7) Remove the liquid line mounting clamp fas-
tener located near the service port (Fig. 9).

entering the refrigerant system.
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.
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) Place the liquid line in the vehicle.
(2) Install the liquid line fitting to the receiver/
drier. Tighten the fastener to 13.6 N·m (10 ft. lbs.).
(3) Install the liquid line mounting clamp fastener
located near the service port. Tighten the fastener to
6.8 N·m (5 ft. lbs.).
(4) Install the liquid line fastener at the condenser.
Tighten the fastener to 23 N·m (17 ft. lbs.).
(5) Connect the receiver/drier bracket fastener and
the bracket to the strut panel.
(6) Install the the short receiver/drier to evapora-
tor line. Tighten the fastener to 13.6 N·m (10 ft. lbs.).
(7) Connect the a/c line to the expansion valve.
Tighten the retaining bolt to 23 N·m (17 ft. lbs.).
(8) Install the engine air inlet tube and the air dis-
tribution duct on vehicles equipped with 3.2/3.5 L
engines(Refer to 9 - ENGINE/AIR INTAKE SYSTEM/
AIR CLEANER ELEMENT - INSTALLATION).
(9) Evacuate the refrigerant system. (Refer to 24 -
HEATING & AIR CONDITIONING/PLUMBING -
STANDARD PROCEDURE - REFRIGERANT SYS-
TEM EVACUATE)
(10) Charge the refrigerant system. (Refer to 24 -
HEATING & AIR CONDITIONING/PLUMBING -
STANDARD PROCEDURE - REFRIGERANT SYS-
TEM CHARGE)
