ADJUSTMENT - DIFFERENTIAL SIDE GEAR
END PLAY
Measure side gear end play: Insert feeler gauges
180É apart between differential side gear and thrust
washer as shown in (Fig. 124). Measurement taken
here applies to both sides. Side gear end play should
be between 0.025-0.152 mm (0.001-0.006 in.). If clear-
ance is greater than 0.152 mm (0.006 in.), install a
thicker thrust washer (both sides). If clearance is less
than 0.025 mm (0.001), install a thinner thrust
washer (both sides). Refer to (Fig. 125) for available
side gear shim thicknesses.
If end play measurement indicates a thrust washer
change is necessary, the differential must be disas-
sembled. (Refer to 21 - TRANSMISSION/TRANS-
AXLE/MANUAL/DIFFERENTIAL - DISASSEMBLY)
FLUID
STANDARD PROCEDURE
STANDARD PROCEDURE - FLUID LEVEL
CHECK
NOTE: For proper fluid level check intervals, (Refer
to LUBRICATION & MAINTENANCE/MAINTENANCE
SCHEDULES - DESCRIPTION)
The fluid required in this transaxle is Mopart
ATF+4 (Automatic Transmission FluidÐType 9602).
Use of substitute fluids may result in improper
transaxle operation and/or failure.
(1) Raise vehicle on hoist.(2) Remove transaxle fill plug (Fig. 126).
(3) Inspect fluid level. Fluid should be within 1/8º
below fill hole. Add MopartATF+4 (Automatic Trans-
mission FluidÐType 9602) as neccessary.
(4) Install fill plug, ensuring it is properly seated.
(5) Lower vehicle.

INSTALLATION - COMPRESSOR MOUNTING
BRACKET - 2.4L ENGINE
(1) Position the compressor mounting bracket onto
the engine.
(2) Install and tighten the four screws that secure
the compressor mounting bracket to the engine.
Tighten the screws to 54 N´m (40 ft. lbs.).
(3) Reinstall the compressor onto the mounting
bracket. (Refer to 24 - HEATING & AIR CONDI-
TIONING/PLUMBING/COMPRESSOR - INSTALLA-
TION).
CONDENSER
DESCRIPTION
The condenser is integral to a cooling module
which includes the radiator, the electric cooling fan,
the fan shroud, air seals and an automatic transmis-
sion oil cooler. The cooling module is located in the
air flow in the front of the engine compartment
behind the radiator grille. The condenser cannot be
repaired or adjusted and, if faulty or damaged, it
must be replaced. The condenser may be removed
from the cooling module for service without removing
the cooling module from the vehicle.
OPERATION
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. When the refrigerant gas gives up
its heat, it condenses. When the refrigerant leaves
the condenser, it has become a high-pressure liquid
refrigerant. The volume of air flowing over the con-
denser fins is critical to the proper cooling perfor-
mance of the air conditioning 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 air flow. Also, any factory-installed air seals
or shrouds must be properly reinstalled following
radiator or condenser service.
REMOVAL
WARNING: REFER TO THE APPLICABLE WARN-
INGS AND CAUTIONS FOR THIS SYSTEM BEFORE
PERFORMING THE FOLLOWING OPERATION.
(Refer to 24 - HEATING & AIR CONDITIONING/
PLUMBING - FRONT - WARNING - A/C PLUMBING)
and (Refer to 24 - HEATING & AIR CONDITIONING/
PLUMBING - FRONT - CAUTION - A/C PLUMBING).NOTE: Before removing the condenser, note the
location of each of the radiator and condenser air
seals. These air seals are used to direct air through
the condenser and radiator. The air seals must be
reinstalled in their proper locations in order for the
air conditioning and engine cooling systems to per-
form as designed.
(1) Recover the refrigerant from the refrigerant
system. (Refer to 24 - HEATING & AIR CONDI-
TIONING/PLUMBING - FRONT/REFRIGERANT -
STANDARD PROCEDURE - REFRIGERANT
RECOVERY).
(2) Remove the two large screws that secure the
front fascia and the outboard ends of the radiator
sight shield to the radiator closure panel crossmem-
ber (Fig. 4).
(3) Remove the five small screws that secure the
front fascia grille inserts to the radiator sight shield.
(4) Remove the radiator sight shield from the radi-
ator closure panel crossmember.
(5) Remove the two screws that secure the hood
latch unit to the front of the radiator closure panel
crossmember and move the latch out of the way over
the top of the crossmember. Mark the location of
latch for reinstallation.
(6) Disconnect the hoses from the transmission oil
cooler fittings on the left side of the cooling module.
(Refer to 7 - COOLING/TRANSMISSION/TRANS
COOLER LINES - REMOVAL).
(7) Remove the nut that secures the discharge line
fitting to the condenser on the right side of the cool-
ing module.
