STANDARD PROCEDURE - REFRIGERANT
SYSTEM CHARGE
WARNING: REVIEW THE WARNINGS AND CAU-
TIONS IN THE FRONT OF THIS SECTION BEFORE
PERFORMING THE FOLLOWING OPERATION.
(Refer to 24 - HEATING & AIR CONDITIONING/
PLUMBING - WARNING) (Refer to 24 - HEATING &
AIR CONDITIONING/PLUMBING - CAUTION)
After the refrigerant system has been tested for
leaks and evacuated, a refrigerant charge can be
injected into the system. (Refer to 24 - HEATING &
AIR CONDITIONING/PLUMBING - SPECIFICA-
TIONS - CHARGE CAPACITY)
A R-134a refrigerant recovery/recycling/charging
station that meets SAE Standard J2210 must be
used to charge the refrigerant system with R-134a
refrigerant. Refer to the operating instructions sup-
plied by the equipment manufacturer for proper care
and use of this equipment.
SPECIFICATIONS
SPECIFICATIONS
The R-134a refrigerant system charge capacity for
this vehicle is: 0.907 kilograms (32 ounces).
A/C COMPRESSOR
DESCRIPTION - A/C COMPRESSOR
The air conditioning system uses a Sanden
SD7H15 seven cylinder, reciprocating wobble plate-
type compressor on all models. This compressor has a
fixed displacement of 150 cubic centimeters (9.375
cubic inches), and has both the suction and discharge
ports located on the cylinder head. A label identifying
the use of R-134a refrigerant is located on the com-
pressor.
DESCRIPTION - HIGH PRESSURE RELIEF
VALVE
A high pressure relief valve is located on the com-
pressor cylinder head, which is at the rear of the
compressor. This mechanical valve is designed to
vent refrigerant from the system to protect against
damage to the compressor and other system compo-
nents, caused by condenser air flow restriction or an
overcharge of refrigerant.
OPERATION - A/C COMPRESSOR
The compressor is driven by the engine through an
electric clutch, drive pulley and belt arrangement.
The compressor is lubricated by refrigerant oil that iscirculated throughout the refrigerant system with the
refrigerant.
The compressor draws in low-pressure refrigerant
vapor from the evaporator through its suction port. It
then compresses the refrigerant into a high-pressure,
high-temperature refrigerant vapor, which is then
pumped to the condenser through the compressor dis-
charge port.
The compressor cannot be repaired. If faulty or
damaged, the entire compressor assembly must be
replaced. The compressor clutch, pulley and clutch
coil are available for service.
OPERATION - HIGH PRESSURE RELIEF VALVE
The high pressure relief valve vents the system
when a discharge pressure of 3445 to 4135 kPa (500
to 600 psi) or above is reached. The valve closes with
a minimum discharge pressure of 2756 kPa (400 psi)
is reached.
The high pressure relief valve vents only enough
refrigerant to reduce the system pressure, and then
re-seats itself. The majority of the refrigerant is con-
served in the system. If the valve vents refrigerant, it
does not mean the valve is faulty.
The high pressure relief valve is a factory-cali-
brated unit. The valve cannot be adjusted or
repaired, and must not be removed or otherwise dis-
turbed. The valve is only serviced as a part of the
compressor assembly.
DIAGNOSIS AND TESTING - A/C COMPRESSOR
When investigating an air conditioning related
noise, you must first know the conditions under
which the noise occurs. These conditions include:
weather, vehicle speed, transmission in gear or neu-
tral, engine speed, engine temperature, and any
other special conditions. Noises that develop during
air conditioning operation can often be misleading.
For example: What sounds like a failed front bearing
or connecting rod, may be caused by loose bolts, nuts,
mounting brackets, or a loose compressor clutch
assembly.
Drive belts are speed sensitive. At different engine
speeds and depending upon belt tension, belts can
develop noises that are mistaken for a compressor
noise. Improper belt tension can cause a misleading
noise when the compressor clutch is engaged, which
may not occur when the compressor clutch is disen-
gaged. Check the serpentine drive belt condition and
tension as described in Cooling before beginning this
procedure.
(1) Select a quiet area for testing. Duplicate the
complaint conditions as much as possible. Switch the
compressor on and off several times to clearly iden-
tify the compressor noise. Listen to the compressor
while the clutch is engaged and disengaged. Probe

UNDER HOOD
INSPECTION - HOOD LATCH/SAFETY CATCH
(1) Check operation of hood latch (Fig. 2) and
safety catch (Fig. 3) adjust as required.
NOTE: The safety catch prevents the hood from
going to full open position until it is manually
released. To test the safety catch, unlock the hood
with the interior release, then try to raise the hood
without operating the safety catch.
INSPECTION - FLUID LEVELS
ENGINE OIL
CAUTION: Use only oil that meets the specified
requirements.
NOTE: If oil level is low, inspect for oil leaks.
(1) Check engine oil level. The oil should be in the
safe range or between the minimum and maximum
marks.
²If the oil level is at the minimum mark, add oil
that meets specifications, (Refer to LUBRICATION &
MAINTENANCE/FLUID TYPES - DESCRIPTION).
²The best time to check the oil is about 5 minutes
after a fully warmed-up engine is turned off, or
before starting the engine after it has been off over-
night.²For the most accurate readings, the vehicle
should be on level ground.
²Wipe up any excess oil that may have spilled, or
the customer could mistakenly perceive this as the
result of a leak.
AUTOMATIC TRANSMISSION
CAUTION: Only use fluid that meets the vehicle's
specific requirement.
NOTE: Mopar ATF Plus contains special additives
not found in Mercon and Dexron II fLuids. Use of
fluid other than Mopar Plus (when specified) could
result in an upshift shudder in some applications.
Transmission fluid check procedures are specific to
each vehicle line. Refer to the appropriate service
information for correct procedure.
CLUTCH MASTER CYLINDER
CAUTION: only use brake fluid that meets specified
requirements (DOT 3 and MVSS 116).

INSPECTION - BATTERY
When battery is easily accessible, check the test
indicator (green dot), terminal tightness and felt
(grease) washer on battery posts. Recharge battery as
required to assure that the green dot is visible.
When battery is not easily accessible check battery
condition with a voltmeter at the jump start loca-
tions, or check the voltmeter on the instrument panel
(Fig. 11) or (Fig. 12). The reading should be at least
12.4 volts. Recharge battery as required.
NOTE: Refer to service information for proper bat-
tery charging rates and times.
INSPECTION - WIRING
The assembly plant has shipped all vehicles with
the interior lights and most electronic memories non-
functional by way of an Ignition Off Draw (IOD) fuse
removed. The purpose is to reduce the possibility of
battery run-down during shipping and storage.
Vehicles stored after prep should have the IOD
fuse that activates the accessories pulled to prevent
battery drain.
NOTE: Ensure that the IOD fuse is removed to pre-
vent battery drain and possible damage. Vehicles
stored for extended periods after prep should be
washed frequently, to prevent environmental dam-age, and reinspected for storage-related problems
before delivery.
(1) Install the IOD fuse as equipped. (ON vehicles
being delivered, remember to reset radio, clock, com-
pass, etc., as required.)
(2) Check routing and connections of all underhood
wiring-reroute and connect as required.
(3) Make sure the starter, generator and air condi-
tioning clutch wiring are correctly installed, routed,
and in the clips where provided.
(4) For predelivery storage, always pull the IOD
fuse that activates accessories.
