STANDARD PROCEDURE - REFRIGERANT OIL
LEVEL
When an air conditioning system is assembled at
the factory, all components except the compressor are
refrigerant oil free. After the refrigerant system has
been charged and operated, the refrigerant oil in the
compressor is dispersed throughout the refrigerant
system. The accumulator, evaporator, condenser, and
compressor will each retain a significant amount of
the needed refrigerant oil.
It is important to have the correct amount of oil in
the refrigerant system. This ensures proper lubrica-
tion of the compressor. Too little oil will result in
damage to the compressor. Too much oil will reduce
the cooling capacity of the air conditioning system.
It will not be necessary to check the oil level in the
compressor or to add oil, unless there has been an oil
loss. An oil loss may occur due to a rupture or leak
from a refrigerant line, a connector fitting, a compo-
nent, or a component seal. If a leak occurs, add 30
milliliters (1 fluid ounce) of refrigerant oil to the
refrigerant system after the repair has been made.Refrigerant oil loss will be evident at the leak point
by the presence of a wet, shiny surface around the
leak.
Refrigerant oil must be added when a accumulator,
evaporator coil, or condenser are replaced. See the
Refrigerant Oil Capacities chart. When a compressor
is replaced, the refrigerant oil must be drained from
the old compressor and measured. Drain all of the
refrigerant oil from the new compressor, then fill the
new compressor with the same amount of refrigerant
oil that was drained out of the old compressor.

DIAGNOSIS AND TESTING - AIR INJECTION
PUMP
The air injection system and air injection
pump is not completely noiseless.Under normal
conditions, noise rises in pitch as engine speed
increases. To determine if excessive noise is fault of
air injection system, disconnect accessory drive belt
and temporarily operate engine.Do not allow
engine to overheat when operating without
drive belt.
CAUTION: Do not attempt to lubricate the air injec-
tion pump. Oil in the pump will cause rapid deteri-
oration and failure.

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).
Check the clutch master cylinder fluid level. Add
fluid to the proper level if necessary.

COOLING SYSTEM RESERVOIR
WARNING: DO NOT REMOVE RADIATOR CAP
WHILE COOLING SYSTEM IS UNDER PRESSURE.
NOTE: Add coolant only to plastic reserve tank if it is
required. Engine must be at normal operating temper-
ature before adding coolant to reserve tank. In cold
climates, coolant in reserve tank may appear low; do
not add coolant until normal temperature is reached.
Check coolant level with engine idling at normal
operating temperature. Coolant level in plastic
reserve tank must be between the minimum and
maximun marks (Fig. 7).
If coolant is added, use a 50/50 (-309F protection) con-
centration of the recommended (Refer to the Service
Information for specificate Mopartantifreeze recom-
mendation ) antifreeze and distilled water. Use a
higher concentration (up to 65%) if a lower freeze point
is required. Do not use recycled coolant in new vehicles.

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.
