SUMMARY OF LUBRICATION AND
MA1NTENANCE SERVICES
Maintenance and lubrication service recommenda-
tions for Chrysler Corporation-built Dodge cars have
been compiledto provide maximum protection for the
car owner’s investment against all reasonable types
of driving conditions.
Since these conditions vary with the individual car
owner’s driving habits, the area
in which the car is
operated and the type of service to which the car is
subjected, it is necessary to prescribe lubrication and

Information pertaining to Lubrication and Main-
tenance requirements is shown on charts (Figs.
1 and
2) and on the Schedule.
Vehicles operated under conditions not classified as
normal service for passenger cars, such as in trailer
towing service, operation at higher than normal load-
ing,
or police or taxicab operation, require servicing
at more frequent intervals.
This information is in-
cluded in each group under the heading “Trailer
Towing,Package and Severe Service”.
CLASS1FlCAT10N OF LUBRICANTS
Oils, lubricants and greases are classified and
graded according to standards recommended by the
Societyof Automotive Engineers
(SAE), the American
Petroleum Institute (API) and the National Lubricat-
ing Grease Institute (NLGI).
Engine Oil
The SAE grade number indicates the Viscosity of
engine oils, for example, SAE 30, which is a single
grade oil, Engine oils are also identified by a dual

housing.
Floor Jack
A regular floor jack may be used under the rear
axle housing, or under the front suspension lower
control arms,
however, a floor iack must never be
used on any partsof the underbody.
CAUTION: Do not attempt to raise one entireside of
the vehicle by placing a jack midway between the
front and rear wheels. This practice may result in
permanentdamage to the body.

The ball joints should be inspected every six
months, or whenever vehicle is serviced for other
reasons,
for damage to seals which can result in loss
of lubricant. Clean accumulated dirt and lubricant
from outside surfaces of seals to permit thorough in-
spection.
Replace damaged

REAR AXLE
Standard and Sure-Grip
The lubricant installed in the rear axle at time of
assembly
is a high quality product and regularly
scheduled changes
of the lubricant are not recom-
mended in vehicles where operation
is classified as
normal passenger car service.
The only exceptions, however, would be where
the lubricant has become contaminated with water,
or in the case of the standard rear axle, to provide
the correct viscosity grade for the anticipated tem-
perature range, as indicated by the accompanying

Trailer TowingService
For vehiclesequipped for trailer towing service, the
axle fluid level should be checked every
3 months or
4,000 miles, whichever occurs first. The lubricant
should be drained and axle refilled with the specified
lubricant, every
36 months or 36,000 miles, whichever
occurs first.
If the axle
is submerged in water, such as on a boat
launching ramp where water can enter the axle vent,
and contamination is suspected
or evident,replace the
lubricant immediately to avoid early axle failure.
BRAKES
The brakes on all models equipped with drum
brakes, except police cars, taxicabs, vehicles equipped
with high-performance engines and trailer towing
package, are equipped with a self-adjusting mech-
anism which makes
it unnecessary to perform major
brake adjustments.
Inspect brake linings for wear every
12 months or
12,000 miles, whichever occurs first. Replace linings,
if necessary. At this time, lubricate contact areas of
brake shoe supports, on models with drum brakes,
with a very thin film of high-temperature lubricant
such as Chrysler Support Plate Lubricant available
under Part Number
2932524.
To perform this service, first remove the brake
shoes. Next, clean the contact surfaces on the shoes
and supports by sanding lightly with fine sandpaper.
Then, carefully apply lubricant.
On models equipped with disc brakes, inspect the
discs, calipers and linings every
12 months or 12,000
miles, whichever occurs first, as outlined under
“Brakes”, Group
5.
HYDRAULIC BRAKE SYSTEM
Every six months, check fluid level in both reser-
voirs of master cylinder by removing screw, clamp
and cover,
or bail and cover, depending upon method
of securing cover (Fig.
12). Level should be within
one-quarter inch of top of reservoir. Avoid damaging
cover gasket.
CAUTION: Before removing master cylinder cover,
wipe
it clean to prevent dirt and other foreign mat-
ter fromdrominainto reservoir.

under Part Number 2421352.
Brake Hoses
Inspect brake hoses for cracking, abrasions, cuts or
tears in outer covering. Examine all connections for
fluid leakage and correct, or replace, where necessary.
Pedal Pivot Bushings
The plastic bushings at the upper end of the brake
pedal should be serviced every
24 months or 24,000
miles, whichever occurs first, or at time of major
brake service. The bushings, located on the brake
pedal pivot on all models and on the lower linkage
pivots on Coronet and Charger models equipped with
power brakes, should be removed, thoroughly cleaned
and relubricated with a multi-purpose grease such
as Multi-Mileage Lubricant, Part Number
2525035.
PARKING BRAKE MECHANISM
Dart Models use a hand-operated parking brake
lever (Fig.
13). Coronet and Charger models use a
foot-operated lever (Fig.
14).
Pivot points indicated should be lubricated, as re-
quired, to maintain ease of operation. Apply a film
of smooth, white body hardware lubricant conform-
ing to NLGI grade
1. Lubriplate, Part Number
1064768, is a type of lubricant recommended for
this purpose.
When the hand lever can be pulled to more than
four inches,
or the foot pedal depressed more than
four and one half inches, the brake cable should
be
adjusted. For adjusting procedure, refer to “Parking
Brakes,” Group
5.

COOLING SYSTEM
The cooling system of all cars is protected against
corrosion and freezing as they leave the factory. A
permanent type anti-freeze is added to provide pro-
tection to -20°F. Higher percentages of anti-freeze
must be added where temperatures below -20°F. are
anticipated.
All engines, except the 170 cubic inch engine, are
equipped with 190 degree thermostats. The 170 cubic
inch is provided with a
200 degree thermostat and
only permanent type anti-freeze should be used. Alco-
hol base anti-freeze products should not be used be-
cause of their low boilingpoints.
Inspect coolant level every two months and refill
as necessary. Once a year, preferably
in the fall, the
cooling system should be drained and refilled. This
draining and refilling procedure, however, need not
be performed until the fall following the vehicle’s
first full year of operation. Drain
V-8 engine cooling
system by removing drain plugs in sides of cylinder
block and opening drain cock in lower radiator tank.
On 6cylinder engines, remove the single drain plug
in right side of engine and open drain cock in lower
radiator tank.
Discardold solutions.
Flush the system thoroughly with water. If there is
an indication that the system contains a considerable
amount of sediment, use a reliable cooling system
cleaner to loosen the sediment. Rinse thoroughly to
remove deposits.
At this time, check water pump belt tension and
check hose connections fortightness.
In areas where protection from freezingis required,
refill cooling system with clean, soft water and a suit-
able high quality, permanent type anti-freeze, in suf-
ficient quantity to provide full protection for the low-
est anticipated temperature, but never
less than 40
percent of the cooling system capacity to ensure ade-
quate protection against corrosion.
If it becomes
necessary to add coolant during the cold weather
season, be sure the system contains sufficient anti-
freeze to provide protection at least to -20 degrees
F. A suitable high quality permanent type anti-freeze
is availableunder Part Number 1316209.
When vehicle
is operated in areas where protection
from freezing
is not required, and vehicle is not
equipped with air conditioning, refill cooling system
with clean, soft water and add a high quality corrosion
inhibitor, such as Chrysler Rust Resistor,
Part Num-
ber 2421778. This need not be done until the first
yearly service.
If the vehicle
is equipped with air conditioning,
the cooling system must contain anti-freeze all year
round.
This is necessary because in the reheat-cycle
system used on all vehicles, except Dart models,
cold, refrigerated air passes through the heater core.
Anti-freeze
is necessary to prevent coolant in the
heater core from freezing in hot weather when the
air conditioner
is being used. For complete informa-
tion refer to “Air Conditioning”,Group 24.
ALTERNATOR
The alternator is provided with prelubricated bear-
ings, which require no periodic lubrication.
BATTERY
Every two months, or more often in hot weather
and on long trips, check fluid level of cells. Restore
level to
3/8 inch above plates, using only water of a
known low mineral content. Do not overfill.
Check specific gravity, using a reliable hydrometer,
every 12 months
or 12,000 miles, whichever occurs
first, or more often if there is excessiveuse of water.
Clean battery posts and cable terminals and tighten
terminals. Coat connections with light mineral grease
or petrolatum.
Refer to “Electrical,” Group
8, for complete serv-
icing.

this time, apply
1 drop of light engine oil to felt wick
under rotor.
CAUTION: Avoid oversiling and applying an excet
rive amount of cam lubricant to prevent lubricants
fromspreadingto breaker contacts.
HEADLIGHTS
To assure correct adjustment of headlight aiming,
it is recommended that the headlights be checked
and,
if necessary, re-aimed properly every six months.
Changes in front and rear suspension, such as front
suspension height and/or deflection of ‘rear springs
due to heavy loading,
will change the headlight beam
pattern and may cause unsafe nighttime driving con-
ditions.
If a vehicle
is to be loaded abnormally, such as for
a vacation trip,
or with a salesman’s products, the
headlight aiming should be checked and adjusted to
serve the new conditions. Refer to “Electrical Sys-
tem,” Group
8, for adjusting procedures.
WINDSHIELD WIPER BLADES
Long exposure to heat and road splash tend to
harden rubber wiper blades, thus destroying their
efficiency. When blades smear
or in general do not
satisfactorily clean the windshield, they should be
replaced.
To replace, depress release on top of blade bridge
and slide out rubber blade. Slide new rubber blade
refill into bridge and lock it in place. Refer to Parts
List
for correct rubber blade refill.
ENGINE OIL-SELECTION OF
For best performance, and to provide for maximum

protection of all engines for all types of operation,
onlythose lubricants should be selected which:
(a) Conform to the requirements
of the API classi-
fication “FOR SERVICE
MS.”
(b) Have the proper SAE grade number for the ex-
pected temperature range.
Oils used
in our engines, labeled “For Service
MS”, should equal or exceed the Engine Oil Perform-
ance Rating Sequence Tests for varnish, sludge and
rusting, when tested according to the methods estab
lished
by the car manufacturer.
All Season Supreme and Supreme Motor Oils, avail-

F. during some winter months. If your region is in
the shaded area (Fig. 17), SAE 5W-20 oil should be
used during the winter months only in engines speci-
fied.
Lubricants which do not have both an
SAE grade
number and an MS Service classification on the con-
tainer should not be used.
IMPORTANT: If a vehicle equipped with a 426
Hemi engine is to be used in competition or other
forms of high performance service, use only the
oil
viscosity grades listed for Summer usage, regardless
of ambient temperature. For this type of service, a
more frequent oil change is also necessary to limit
the effects of oil deterioration.
MATERIALS ADDED TO ENGINE OILS
It is not necessary to add any other products to
engine oils for most types of driving when
MS quality
oils are used.
In some instances, such as infrequent operation
or
short trips only, and during break-in after a major
overhaul, addition of special materials containing
anti-rust and anti-scuff additives is beneficial. A prod-
uct suitable for this purpose
is available under Part
Number
1879406, Engine Oil Supplement.
FREQUENCY OF ENGINE OIL CHANGES
The by-products of combustion, such as unburned
fuel, condensation and carbon deposits, in addition to
dust and other abrasive materials, tend to contaminate
engine oil. If permitted to remain in the crankcase for
too great a period of time, the contaminates reduce
the lubricating qualities of the oil causing excessive
wear which can materially affect the operating effi-
ciency of the engine.
To provide maximum protection to engine parts,
it
is recommended under normal operating conditions,
Severe OperatingConditions
Severe operating conditions, such as frequent driv-
ing on dusty roads,
or in sandy geographic areas, or
unusually short trip driving in cold weather may
reasonably require oil changes more frequently than
every three months. Under these conditions, consult
and follow the advice of any Chrysler Motors Corpora-
tion Authorized Dealer’s Service Manager.
that engine oil be drained and replenished with new
oil
of the proper viscosityand API classification, every
three
(3) months or 4,000 miles, whichever occurs
first.
When draining the old oil, it is recommended that
the engine be at normal operating temperature, as the
warmed oil
will drain more readily and carry with it
such foreign matter which might otherwise cling to
the sides of the crankcase and the various moving
parts.
A greater degree of contamination of the engine
oil takes place when the vehicle
is operated under
adverse conditions, such as frequent driving in dusty
areas, short trips, stop-and-godriving and where long
periods of idling are experienced. For oil change fre-
quencies under these operating conditions, refer to
the recommendations in the paragraphs under Severe
Operating Conditions and Taxi and Police Operation.
During Break-ln
Cars should be driven moderately during the first
300 miles. Speeds up to 50 to 60 mph are desirable.
While cruising, brief full-throttle accelerations con-
tribute to a good break-in. Wide-open throttle accel-
erations in low gear can be detrimental and should
be avoided for atleast
500 miles.
The oil installed in the engine at the factory is a
high-quality lubricant, classified “For Service MS,”
and
should be retained until the first regularly
scheduled three-month
or 4,000 mile oil change,
whichever occurs first. If it becomes necessary to add
oil during this initial period, an oil with the “For
Service MS” classification and of the proper viscosity
grade should be used.
Nondetergent or straight
mineral
oils must never k used.
Oil level should be checked during each stop for
gasoline. Oil should be added only when level on oil
level indicator
is at or below “ADD OIL” mark.
Frequently, a new engine will coiisume some oil
during its first few thousand miles of operation. This
should be considered as a normal part of the break-in
and not interpreted as an indication of difficulty.

ENGINE OIL FILTERS
All engines are equipped with full-flow, throwaway
oil filters (Figs.
18, 19, 20 or 21) to provide efficient
filtering of engine oil for maximum engine protection.
The filter should be replaced every second
oil
change. Since filters vary widely in quality, it is rec-
ommended that a Chrysler Corporation Engine
Oil
Filter, or equivalent, be used for replacement to as-
sure most efficient service.
CRANKCASE VENTILATION SYSTEM
All models are equipped with a fully closed crank-
case ventilation system (Fig.
22). This system has a
closed
oil filler cap with a hose connecting the filler
cap to the carburetor air cleaner housing. This pro-
vides theair inlet for the system.
The air drawn from the carburetor air cleaner
through the connecting hose to the filler cap (Fig.
23) is circulated through the engine and drawn out
of the cylinder head cover, through a valve mounted
in the cover, by manifold vacuum; through another
Fig. 20-Engine OilFilter (3 18 Cu. In. Engine)
buretor throttle valve body, into the combustion
chamber, and dispelled with the exhaust gases.
ServicingFrequencies
Proper maintenance of the crankcase ventilation
system
is required to keep the system clean and main-
tain good engine performance and durability. Periodic
servicing
is required to remove combustion products
from the ventilator valve, hoses, carburetor passages
and oil filler cap.
Every
six months the system must be tested for
proper operation and cleaned if necessary. This in-
cludes inspecting the operation of the valve, checking
the hoses and carburetor passages for deposits and
cleaning the oil filler cap and carburetor air cleaner.
The crankcase ventilator valve must be replaced
with a new one every year. The carburetor air cleaner
filter element must be replaced
every year on High
Performance Vehicles equipped with “Fresh Air In-
duction System”, and
every 2 years for vehicles
equipped with standard air cleaner.
If the car is used extensively for short trips with
frequent idling, the ventilation system may require
servicing more frequently.
Servicing Procedure
Remove hose from carburetor air cleaner (Fig. 24).

ENGINE PERFORMANCE EVALUATION
Engine operating efficiency depends on correct ijp
nition, carburetor adjustments, and on correct valve
lash where applicable. To obtain best engine per-
formance, Chrysler Corporation recommends that
the engine be evaluated every
12 months or 12,000
miles, whichever occurs first, and tuned, if necessary.
Services performed during this evaluation should in-
clude the following.
1-Spark Plugs-Remove and inspect each spark
plug. Most plugs can be cleaned, adjusted, and rein-
stalled. Rough idle, hard starting, frequent engine
miss at high speeds, or apparent physical deteriora-
tion, are indications that the spark plugs should be
replaced.
2-Distributor-Inspect distributor cap and rotor.
Test resistance of secondary cables. Check breaker
contacts for abnormal pitting, bluing, or misalign-
ment, and adjust, if serviceable,
or replace. Lubricate
cam and wick, (see page
11). See “Ignition System”
Group
8 Electrical, for tests and adjustments.
3-Carburetor-Remove and clean air filter. Check
operation of manifold heat control valve shaft, choke
valve shaft and choke diaphragm; use solvents rec-
ommended. Clean crankcase ventilation system,
(see
page 14). See “Fuel System,” Group 14, for carburetor
adjustment procedures.
4-Battery-Check specific gravity. Clean and
tighten terminals; apply grease to posts and termi-
nals. Check circuit voltages as described in “Electri-
cal,” Group
