INTRODUCTION
Chrysler Corporation has compiled recommended
lubrication and maintenance schedules and proce-
dures to help reduce premature wear or failure over
a broad range of operating conditions. When select-
ing the proper maintenance schedule, the climate
and operating conditions must be considered. A vehi-
cle subjected to severe usage requires service more
frequently than a vehicle used for general transpor-
tation.
PARTS AND LUBRICANT RECOMMENDATIONS
When service is required, Chrysler Corporation rec-
ommends that only Mopar tbrand parts, lubricants
and chemicals be used. Mopar tprovides the best en-
gineered products for servicing Chrysler Corporation
vehicles.
SEVERE SERVICE
If a vehicle is operated under any of the following
conditions, it is considered severe service.
² Extremely dusty areas.
² 50% or more of vehicle operation in 32ÉC (90ÉF) or
higher temperatures.
² Prolonged idling ( such as, vehicle operation in
stop and go traffic).
² Frequent short running periods. Not allowing en-
gine to warm to operating temperatures.
² Police or taxi usage.
FUEL USAGE
All Chrysler Corporation engines require the use of
unleaded fuel to reduce exhaust emissions. Use fuel
with a minimum octane rating of 87,(R + M)/2. See
Engine section of this group for Fuel Recommenda-
tions.
CLASSIFICATION OF LUBRICANTS
Only lubricants that are endorsed by the following
organizations standards should be used to service a
Chrysler Corporation vehicle.
² Society of Automotive Engineers (SAE)
² American Petroleum Institute (API)
² National Lubricating Grease Institute (NLGI)
ENGINE OIL
SAE GRADE RATING INDICATES ENGINE OIL VISCOSITY
² SAE 30 = single grade engine oil.
² SAE 5W-30 = multiple grade engine oil.
API QUALITY CLASSIFICATION.
² SG service engine oil is a high quality crankcase
lubricant designed for use in all naturally aspirated
engines.
² SG/CD service engine oil is a high quality crank-
case lubricant designed for use in most naturally as-
pirated and turbocharged gasoline or diesel engines.
GEAR LUBRICANTS
SAE ratings also apply to multiple grade gear lu-
bricants. In addition, API classification defines the
lubricants usage.

FREQUENCY OF ENGINE OIL AND FILTER
CHANGES
ENGINE OIL
Road conditions as well as your kind of driving af-
fect the interval at which your oil should be changed.
Check the following to determine if any apply to you:
² Frequent short trip driving less than 8 kilometers
(5 miles)
² Frequent driving in dusty conditions
² Frequent trailer towing
² Extensive idling (such as vehicle operation in stop
and go traffic)
² More than 50% of your driving is at sustained
high speeds during hot weather, above 32ÉC (90ÉF) If any of these apply to you then change your en-
gine oil every 4 800 kilometers (3,000 miles) or 3
months, whichever comes first. If none of these apply to you then change your oil
every 12 000 kilometers (7,500 miles) or 6 months,
whichever comes first. If none of these apply and the vehicle is in com-
mercial type service such as, Police, Taxi or Limou-
sine and principally used for highway driving of 40
kilometers (25 miles) or more between stations, the
engine oil should be changed every 8 000 kilometers
(5,000 miles) or 6 months, whichever comes first.
FLEXIBLE FUEL VEHICLES
Flexible fuel is corrosive and contributes to engine
oil contamination. When flexible fuel is being used,
the engine oil should be changed every 8 000 kilome-
ters (5,000 miles) or 6 months, whichever comes first.
OIL FILTER
The engine oil filter should be replaced with a new
filter at every second oil change.
ENGINE OIL
WARNING: NEW OR USED ENGINE OIL CAN BE IR-
RITATING TO THE SKIN. AVOID PROLONGED OR
REPEATED SKIN CONTACT WITH ENGINE OIL.
CONTAMINANTS IN USED ENGINE OIL, CAUSED
BY INTERNAL COMBUSTION, CAN BE HAZARDOUS TO YOUR HEALTH. THOROUGHLY WASH EX-
POSED SKIN WITH SOAP AND WATER. DO NOT WASH SKIN WITH GASOLINE, DIESEL
FUEL, THINNER, OR SOLVENTS, HEALTH PROB-
LEMS CAN RESULT. DO NOT POLLUTE, DISPOSE OF USED ENGINE
OIL PROPERLY. CONTACT YOUR DEALER OR
GOVERNMENT AGENCY FOR LOCATION OF COL-
LECTION CENTER IN YOUR AREA.
BREAK-IN PERIOD
CAUTION: Wide open throttle operation in low
gears, before engine break-in period is complete,
can damage engine.
On a Chrysler Corporation vehicle an extended
break-in period is not required. Driving speeds of not
over 80-90 km/h (50-55 mph) for the first 100 km (60
miles) is recommended. Hard acceleration and high
engine rpm in lower gears should be avoided.
SELECTING ENGINE OIL
CAUTION: Do not use non-detergent or straight
mineral oil when adding or changing crankcase lu-
bricant. Engine or Turbocharger failure can result.
The factory fill engine oil is a high quality, energy
conserving, crankcase lubricant. The Recommended
SAE Viscosity Grades chart defines the viscosity
grades that must be used based on temperature in
the region where vehicle is operated and optional
equipment.
NON-FLEXIBLE FUEL VEHICLES Chrysler Corporation recommends that Mopar mo-
tor oil, or equivalent, be used when adding or chang-
ing crankcase lubricant. The API symbol (Fig. 1) on
the container indicates the viscosity grade, quality
and fuel economy ratings of the lubricant it contains.
Use ENERGY CONSERVING II motor oil with API
SERVICE SG or SG/CD classification.

ENGINE COOLING SYSTEM
WARNINGS AND PRECAUTIONS
WARNING: ANTIFREEZE IS AN ETHYLENE GLYCOL
BASE COOLANT AND IS HARMFUL IF SWAL-
LOWED OR INHALED. IF SWALLOWED, DRINK
TWO GLASSES OF WATER AND INDUCE VOMIT-
ING. IF INHALED, MOVE TO FRESH AIR AREA.
SEEK MEDICAL ATTENTION IMMEDIATELY. DO
NOT STORE IN OPEN OR UNMARKED CONTAIN-
ERS. WASH SKIN AND CLOTHING THOROUGHLY
AFTER COMING IN CONTACT WITH ETHYLENE
GLYCOL. KEEP OUT OF REACH OF CHILDREN. DISPOSE OF GLYCOL BASE COOLANT PROP-
ERLY, CONTACT YOUR DEALER OR GOVERNMENT
AGENCY FOR LOCATION OF COLLECTION CEN-
TER IN YOUR AREA. DO NOT OPEN A COOLING SYSTEM WHEN THE
ENGINE IS AT RUNNING TEMPERATURE, PER-
SONAL INJURY CAN RESULT. AVOID RADIATOR COOLING FAN WHEN ENGINE
COMPARTMENT RELATED SERVICE IS PER-
FORMED, PERSONAL INJURY CAN RESULT.
CAUTION: Do not use straight antifreeze as engine
coolant, inadequate engine running temperatures
can result. Do not operate vehicle without proper concentra-
tion of recommended ethylene glycol coolant, high
running temperatures and cooling system corrosion
can result.
The engine cooling system will develop internal
pressure of 97 to 123 kPa (14 to 18 psi) at normal op-
erating temperature. Allow the vehicle approxi-
mately one half hour to cool off before opening the
cooling system. As an indicator of pressure, squeeze
the upper radiator hose between index finger and
thumb. If it collapses with little effort the system
would have low internal pressure and should be safe
to open to the first safety notch of the radiator cap.
Refer to Group 7, Cooling System.
COOLING SYSTEM INSPECTION
Coolant level (Fig. 5) should be inspected when
other engine compartment service is performed or
when coolant leak is suspected. Coolant recovery
tank level should read between the MIN and MAX
marks, located on the side of recovery tank, when the
engine is at normal operating temperature. Normal
coolant level maintenance does not require the re-
moval of radiator cap. Cooling system freeze protec-
tion should be tested at the onset of the winter
season or every 12 months. Service is required if
coolant is low, contaminated, rusty or freeze protec-
tion is inadequate. To properly test cooling system,
see Group 7, Cooling System.
The cooling system factory fill is a mixture of 50%
Glycol based antifreeze and 50% water. Using a suit-
able hydrometer, measure antifreeze concentration in
the radiator when the engine is cool. If the cooling
system has recently been serviced, allow coolant to
circulate for at least 20 minutes before taking hy-
drometer reading. Properly mixed coolant will pro-
tect the cooling system to -37ÉC (-35ÉF). If the freeze
protection is above -28ÉC (-20ÉF), drain enough cool-
ant from the cooling system to allow room to add an-

stick.
REAR WHEEL BEARINGS
INSPECTION
The rear wheel bearings should be packed with
new lubricant at the distance interval described in the Lubrication and Maintenance Schedules. Refer to
the General Information section of this group. The
bearings should be inspected for contamination and
wear before they are cleaned. Slight discoloration of
bearing rollers and race cup is normal. If metal

sion vehicles, unfasten clutch cable bracket at shock
tower and move aside. (8) Slide the power brake unit up and to the left
(mounting holes are slotted) on the dash panel, then
tilt inboard and up to remove.
CAUTION: Do not attempt to disassemble power
brake unit as this booster is serviced ONLY as a
complete assembly.
INSTALL (1) Position power brake booster onto dash panel.
(2) Install and tighten the 4 power brake booster to
dash panel mounting nuts (Fig. 5) to 29 N Im (250 in.
lbs.) torque. (3) Install steel heater water line and clutch cable
bracket, if so equipped. (4) Carefully position master cylinder on power
brake unit. (5) Install and tighten the 2 master cylinder to
power booster mounting nuts (Fig. 4) to 29 N Im (250
in. lbs.) torque. (6) Connect vacuum hose onto the check valve, lo-
cated on the power brake unit. (7) Using lubriplate, or equivalent, coat the bearing
surface of pedal pin (Fig. 5). (8) Connect power brake booster input rod to brake
pedal pin and install a NEW retainer clip. Use only a
new retainer clip DO NOT USE the old clip. (9) Check stop light operation.
WHEEL BEARINGS
FRONT WHEEL BEARINGS
Front wheel drive vehicles are equipped with per-
manently sealed front wheel bearings. There is no
periodic lubrication or maintenance recommended for
these units. However if during servicing of the brake
system, service to the front wheel bearing is required
refer to Group 2, Suspension in this service manual.
REAR WHEEL BEARINGS
NORMAL SERVICE
The lubricant in the rear wheel bearings should be
inspected whenever the hubs are removed to inspect
or service the brake system. Or at least every 30,000
miles (48,000 km). The bearings should be cleaned
and repacked with a High Temperature Multipurpose
E.P. Grease whenever the disc brake rotors are re-
surfaced.
INSPECTION
Check lubricant to see that it is adequate in quan-
tity and quality. If the grease is low in quantity, con-
tains dirt, appears dry or has been contaminated
with water, it will appear milky. The bearings then must be cleaned and repacked.
Do not add grease to
a wheel bearing that already has grease packed
in it. Relubricate completely. Mixing of different
types of greases in wheel bearings should be
avoided since it may result in excessive thinning
and leakage of the grease.
REMOVAL AND INSTALLATION
For the servicing, removal and installation of the
rear wheel bearings follow the procedure listed below. (1) Remove the rear tire and wheel assembly.
(2) On rear disc brake equipped vehicles remove the
caliper and rotor. Support the caliper out of the way.
Do not allow the caliper to hang by the hydraulic
hose. See disc brake section in this group for caliper
removal procedure. (3) Remove grease cap, cotter pin, nut lock, nut,
thrust washer and outer wheel bearing. (4) Carefully slide hub or drum from spindle. Do not
drag inner bearing or grease seal over stub axle
(thread, bearing, and oil seal may be damaged.) Using
an appropriate tool remove the grease seal and inner
bearing from the drum or hub. Discard grease
