A/C CONDENSER
DESCRIPTION
The A/C condenser is located in the front of the
engine compartment behind the front fascia. The A/C
condenser is a heat exchanger that allows the high-
pressure refrigerant gas being discharged by the A/C
compressor to give up its heat to the air passing over
the condenser fins, which causes the refrigerant to
cool and change to a liquid state.The A/C condenser may be removed for service
without removing the radiator and cooling fan from
the vehicle.
The A/C condenser for vehicles equipped with the
2.4L/3.3L/3.8L engines are equipped with an integral
automatic transmission cooler and mounting provi-
sions.
OPERATION
When air passes through the fins of the A/C con-
denser, the high-pressure refrigerant gas within the
A/C condenser gives up its heat. The refrigerant then
condenses as it leaves the A/C condenser and
becomes a high-pressure liquid. The volume of air
flowing over the condenser fins is critical to the
proper cooling performance of the A/C system. There-
fore, it is important that there are no objects placed
in front of the radiator grille openings at 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 rein-
stalled following radiator or A/C condenser service.
The A/C condenser cannot be repaired and, if
faulty or damaged, it must be replaced.

A/C EVAPORATOR
DESCRIPTION
The A/C evaporator is located in the HVAC hous-
ing, behind the instrument panel. The evaporator is
positioned in the housing so that all air that enters
the housing must pass over the fins of the evaporator
coils before it is distributed through the system ducts
and outlets. However, air passing over the evaporator
fins will only be conditioned when the compressor is
engaged and circulating refrigerant through the
evaporator tubes.
OPERATION
Refrigerant enters the A/C evaporator from the
expansion valve as a low-temperature, low-pressure
liquid. As air flows over the fins of the evaporator,
the humidity in the air condenses on the fins, and
the heat from the air is absorbed by the refrigerant.
Heat absorption causes the refrigerant to boil and
vaporize. The refrigerant becomes a low-pressure gas
when it leaves the evaporator.
The A/C evaporator cannot be repaired and, if
faulty or damaged, it must be replaced.

(2) Disassemble the HVAC housing to access the
evaporator (Refer to 24 - HEATING & AIR CONDI-
TIONING/DISTRIBUTION/HVAC HOUSING - DIS-

(3) Carefully lift the evaporator and its foam wrap
out of the lower half of the HVAC housing as a unit
(Fig. 15). Be certain not to lose the clam shell type
rubber seal that is fitted to the evaporator inlet and
outlet tubes where they exit the HVAC housing.
INSTALLATION
NOTE: If the evaporator is being replaced, add 50
milliliters (1.7 fluid ounces) of refrigerant oil to the
refrigerant system. Use only refrigerant oil of the
type recommended for the A/C compressor in the
vehicle.
(1) Carefully lower the evaporator and its foam
wrap into the lower half of the HVAC housing as a

EXPANSION VALVE
DESCRIPTION
The front ªHº valve-type thermal expansion valve
(TXV) is located at the dash panel between the liquid
and suction lines, and the A/C evaporator. The
assembly consists of an aluminum H-valve body and
a thermal sensor. On RG models, the evaporator tem-
perature sensor is installed on the top of the expan-
sion valve.
OPERATION
High-pressure, low temperature liquid refrigerant
from the liquid line passes through the expansion
valve orifice, converting it into a low-pressure, low-
temperature mixture of liquid and gas before it
enters the evaporator coil. A mechanical sensor in the
expansion valve control head monitors the tempera-
ture and pressure of the refrigerant leaving the evap-
orator coil through the suction line, and adjusts the
orifice size at the liquid line to let the proper amount
of refrigerant into the evaporator coil to meet the
vehicle cooling requirements. Controlling the refriger-
ant flow through the A/C evaporator ensures that
none of the refrigerant leaving the evaporator is still
in a liquid state, which could damage the compressor.
The A/C expansion valve is a factory calibrated
unit and cannot be adjusted or repaired and, if faulty
or damaged, it must be replaced.
