2. Using a manifold gauge set, a thermocouple and
the Charge Determination Chart (Fig. 1).
A temperature probe is required to measure liquid
line temperature. The clamp-on, Type K thermocou-
ple temperature probe used in this procedure is
available through the DaimlerChrysler Professional
Service Equipment (PSE) program. This probe (PSE
#66-324-0014 or #80PK-1A) is compatible with tem-
perature-measuring instruments that accept Type K
thermocouples, and have a miniature connector
input. Other temperature probes are available
through aftermarket sources; however, all references
in this procedure will reflect the use of the probe
made available through the PSE program.
In order to use the temperature probe, a digital
thermometer will also be required. If a digital ther-
mometer is not available, an adapter is available
through the PSE program that will convert any stan-
dard digital multimeter into a digital thermometer.
This adapter is designed to accept any standard Type
K thermocouple. If a digital multimeter is not avail-
able, this tool is also available through the PSE pro-
gram.NOTE: When connecting the service equipment
couplings to the refrigerant system service ports,
be certain that the valve of each coupling is fully
closed. This will reduce the amount of effort
required to make the connection.
(1) Remove the caps from the refrigerant system
service ports and attach a manifold gauge set or a
R-134a refrigerant recovery/recycling/charging sta-
tion that meets SAE Standard J2210 to the refriger-
ant system.
(2) Attach a clamp-on thermocouple to the liquid
line. The thermocouple must be placed as close to the
A/C pressure transducer as possible to accurately
observe liquid line temperature.
(3) Bring the refrigerant system up to operating
temperature and pressure. This is done by allowing
the engine to run at idle under the following condi-
tions for five minutes.
(a) Front windows are open.
(b) Transaxle in Park.
(c) Front heater-A/C controls set to outside air,
full cool, panel mode, blower high, and compressor
engaged.
(d) If the vehicle is so equipped, the rear heater-
A/C controls must be set to full cool and blower
high.

NOTE: Prior to a vehicle being removed from ser-
vice or stored for more than two weeks, the com-
pressor should be operated to ensure adequate
refrigerant oil distribution throughout the system
components. Turn on the air conditioner for a min-
imum of five minutes with outside air and the high-
est blower speed selected.
BELT NOISE
If the compressor drive belt slips at initial start-up,
it does not necessarily mean the compressor has
failed. The following procedure can be used to iden-
tify a compressor drive belt noise problem.
A. Start the vehicle and run at idle.
B. Turn the air conditioner On and listen for belt
squeal.
C. If belt squeal is heard, turn the air conditioner
Off immediately.
If the belt squeal stops when the air conditioner is
turned Off, perform the following repair procedures.
(1) Using an appropriate sized oil filter wrench or
a strap wrench, grasp the outer diameter of the com-
pressor clutch hub. While facing the compressor,
rotate the hub clockwise, then counterclockwise. If
the hub rotates, proceed to the next step. If the hub
will not rotate, the compressor is internally damaged,
and must be replaced.
(2) Turn the hub clockwise five complete revolu-
tions and remove the tool.
(3) Start the vehicle and run at idle.
(4) Turn the air conditioner On. Observe the com-
pressor and the system for normal operation, noting
cooling performance and noise levels. Operate for five
minutes before turning the air conditioner Off. If
acceptable cooling performance is observed during
compressor operation, the compressor does not need
to be replaced.
(5) Inspect the drive belt for wear, damage, and
proper tension. (Refer to 7 - COOLING/ACCESSORY
DRIVE/DRIVE BELTS - DIAGNOSIS AND TEST-
ING).

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

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.

DIAGNOSIS AND TESTING
FRONT A/C EXPANSION VALVE
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: The A/C expansion valve should only be
tested following testing of the A/C compressor.
NOTE: Liquid CO
2is required to test the A/C expan-
sion valve. This material is available from most
welding supply facilities. Liquid CO
2is also avail-
able from companies which service and sell fire
extinguishers.
When testing the A/C expansion valve, the work
area and the vehicle temperature must be 21É to 27É
C (70É to 85É F). To test the expansion valve:
(1) Connect a charging station or manifold gauge
set to the refrigerant system service ports. Verify the
refrigerant charge level.
(2) Close all doors, windows and vents to the pas-
senger compartment.
(3) Set the A/C-heater controls so that the A/C
compressor is operating, the temperature control is
in the highest temperature position, the mode door is
directing the output to the floor outlets, and the
blower motor is operating at the highest speed set-
ting.
(4) Start the engine and allow it to idle. After the
engine has reached normal operating temperature,
allow the passenger compartment to heat up. This
will create the need for maximum refrigerant flow
into the A/C evaporator.
(5) If the refrigerant charge is sufficient, the dis-
charge (high pressure) gauge should read 965 kPa to
1655 kPa (140 psi to 240 psi). The suction (low pres-
sure) gauge should read 138 kPa to 207 kPa (20 psi
to 30 psi). If OK, go to Step 6. If not OK, replace the
faulty A/C expansion valve.
WARNING:
PROTECT THE SKIN AND EYES FROM EXPOSURE
TO LIQUID CO
2OR PERSONAL INJURY CAN
RESULT.
(6) If the suction (low pressure) gauge reads
within the specified range, freeze the A/C expansion
valve for 30 seconds using liquid CO
2or another suit-able super-cold material.Do not spray R-134a or
R-12 refrigerant on the A/C expansion valve for
this test.The suction (low pressure) gauge reading
should drop by 69 kPa (10 psi). If OK, go to Step 7 If
not OK, replace the faulty A/C expansion valve.
(7) Allow the expansion valve control head to thaw.
The suction (low pressure) gauge reading should sta-
bilize at 138 kPa to 207 kPa (20 psi to 30 psi). If not
OK, replace the faulty A/C expansion valve.
(8) When expansion valve testing is complete, test
the overall A/C system performance (Refer to 24 -
HEATING & AIR CONDITIONING - DIAGNOSIS
AND TESTING - A/C PERFORMANCE TEST).
