Maintenance and lubrication service recommendations for Chrysler Corporation built vehicles have been compiled to provide maximum protection for the car owner's investment against all reasonable types of driving conditions.
Since these conditions vary with the individual owner's driving habits, the area in which the vehicle is operated and the type of service to which the vehicle is subjected, it is necessary to prescribe lubrication and maintenance service on a time frequency as mileage interval basis.
Information pertaining to Lubrication and Maintenance is provided in the "LUBRICATION AND MAINTENANCE SCHEDULES."
Vehicles operating under sever service conditions require more frequent service.
Your Chrysler Corporation vehicle has been engineered to perform for you for years to come. You will occasionally require service and maintenance for your vehicle and Chrysler Corporation recommends the use of "MOPAR" brand parts and accessories. Each MOPAR part has been specifically designed to maintain top efficiency and quality by the same team of engineers who designed your vehicle. Only MOPAR can make this claim.

SEVERE SERVICE MAINTENANCE (FOR TRAILER TOWING, TAXI, POLICE, AND LIMOUSINE SERVICE) . . .Severe service is defined as: Stop and go driving, driving in dusty conditions, extensive idling, frequent short trips, operating at sustained high speeds during hot weather (above +90�F, +32�C). The following maintenance intervals apply for this type of operation.
|Engine Oil||Change every 3 months or 3,000 miles (4,800 km)|

Oils, lubricants and greases are classified and graded according to standards recommended by the Society of Automotive Engineers (SAE), the American Petroleum Institute (API) and the National Lubricating Grease Institute (NLGI).
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 number, for example, SAE 10W-30, which indicates a multigrade oil.
The API classification system defines oil performance in terms of engine usage. Only engine oils designed "For service SF or SF/CC" should be used. These oils contain sufficient chemical additives to provide maximum engine protection. Both the SAE grade and API designation must be found on the container.
The SAE grade number also indicates the viscosity of Multipurpose Gear Lubricants.
The API classification system defines gear lubricants in terms of usage. Typically gear lubricants conforming to API GL-5 with a viscosity of SAE 90 are recommended for rear axles.
Semisolid lubricants, such as specified for universal joints bear the NLGI designation and are further classified as grades 0,1,2,3, etc.
Whenever "Chassis Lubricant" is specified, Multipurpose grease, NLGI grade 2 E.P. should be used. MOPAR Multimilage Lubricant, Part Number 4318062 or equivalent, meets these requirements and is recommended.
These vehicles will operate satisfactorily on gasolines having a minimum octane rating of 87, (R+M)/2, but for increased vehicle performance and fuel economy, the use of premium or super unleaded gasoline, having a minimum octane rating of 91, (R+M)/2, is recommended.
Unleaded gasolines only must be used in vehicles equipped with catalyst emission control systems. All cars, so equipped, have labels located on the instrument panel and adjacent to the fuel filler cap or door that state, "UNLEADED GASOLINE ONLY". These cars also have fuel filler tubes specially designed to accept the smaller diameter unleaded dispensing nozzles only.
The exhaust emission system of your vehicle is designed to meet all emission regulation while at the same time providing excellent fuel economy. Catalyst systems require that only unleaded gasoline be used. Use of leaded fuel will not only destroy the effectiveness of the catalytic converter used to reduce exhaust emissions but will also make part of the carburetor control system inoperative and lead to high fuel consumption.
Vehicles not equipped with catalyst emission control systems may be operated on either leaded or unleaded gasolines having the same anti-knock values shown above.
GASOLINES CONTAINING ALCOHOL
Some gasolines sold at service stations contain alcohol, although they may not be so identified. Use of fuels containing alcohol is not recommended, unless the nature of the blend can be determined as being satisfactory.
GASOHOL - a mixture of 10% ethanol (grain alcohol) and 90% unleaded gasoline may be used in your vehicle. If driveability problems are experienced as a result of using GASOHOL, it is recommended that the vehicle be operated on gasoline.
METHANOL - do not use gasolines containing methanol (wood alcohol). Use of this type of alcohol can result in vehicle performance deterioration and damage critical parts in the fuel pump, carburetor, and other fuel system components. Fuel system damage and vehicle performance problems, resulting from the use of gasolines containing methanol, may not be covered by the new vehicle warranty.
Indiscriminate use of fuel system cleaning agents should be avoided. Many of these materials intended for gum and varnish removal may contain highly active solvents or similar ingredients that can be harmful to gasket and diaphragm materials used in fuel system component parts.
Cooling System - Drain, Flush, and Refill
After three years or 52,500 miles (84 000 km) and every two years or 30,000 miles (48 000 km) thereafter, the system should be drained, flushed, and refilled. If, at any time, the solution is dirty or rusty or contains a considerable amount of sediment, clean and flush with a reliable cooling system cleaner. Follow with a thorough rinsing to remove all deposits and chemicals. Discard old antifreeze solution.
CAUTION: When working in the engine cooling system fan area of the engine compartment, make sure the engine is not running and the crank-start circuit is interrupted (ignition key removed or the negative battery terminal disconnected).
To Drain System - Open radiator drain cock. After the reserve tank (Fig. 1) has stopped draining, remove the radiator cap and the drain plugs in the sides of the engine block. If the coolant re-serve system tank drains first, it is a good means of determining that the radiator pressure cap and hose connections on the radiator and the coolant reserve system provide a good seal.
To Refill System - Close the drain cock and rein-stall drain plugs. Add recommended coolant to the radiator until it is completely filled. Use only a high quality ethylene glycol base anti-freeze coolant, such as MOPAR P/N 4267020 or PRESTONE II, PEAK, or antifreezes containing ALUGARD 340-2 inhibitor system to bring the concentration to a minimum 44% (50% in Canada), but not more than 70%. Start engine and run with pressure cap off until the upper radiator hose feels hot. Add coolant to the radiator, as necessary. Reinstall the radiator pressure cap. Add coolant to the reserve tank until filled to a level between the MIN and MAX marks and maintain this level with engine at normal operating temperature.
If significant air has been trapped during filling, it may be necessary to warm up, then cool down the engine approximately three times to expel all air, while maintaining coolant to the proper level.
Radiator Cap - The radiator cap must be fully tightened in order to provide a good seal to the radiator filler neck to prevent loss of coolant and to insure that coolant will return to the radiator from the coolant reserve tank. The vent valve and its seat can become contaminated with coolant sediment, etc. If system will not go under pressure or the coolant reserve system tank gains coolant abnormally or if the top radiator hose collapses on cool-down, then the valve and seat should be carefully cleaned.
Coolant protection checks should be made every 12 months (prior to the onset of freezing weather, where applicable). If coolant is dirty or rusty in appearance, the system should be drained, flushed and refilled with fresh coolant.
Check radiator cap for proper vacuum sealing and operation. Use caution when removing the radiator cap to avoid contact with hot coolant or steam! Place a cloth over the cap, turn to the first stop, (do not press down) pause to allow pressure to release through the overflow tube, then press down and turn counter-clockwise to remove cap. Check face of radiator for any accumulation of bugs, leaves, etc. Check reserve tank tubing for condition and tightness of connection at reserve tank and radiator. Inspect entire system for leaks.
Check antifreeze coolant. If below 44% (-20�F; -29�C) add ethylene glycol antifreeze to bring the concentration to a minimum of 44% (50% in Canada), but not to exceed 70%. Maintain concentration between 44% (50% in Canada) and 70% for year round protection against corrosion, boiling and freezing.
Failure to follow the antifreeze concentration recommendations and periodic replacement, or failure to use antifreeze formulated to prevent corrosion of all cooling system metals may result in radiator plugging and consequent engine overheating, or in cooling system leaks, such as in core plugs, and subsequent loss of coolant.
ALTERNATOR (back to CONTENTS)
The alternator is provided with prelubricated bearings, which require no periodic lubrication.
BATTERY (back to CONTENTS)
All vehicles are equipped with maintenance free batteries (see Specifications for application). Maintenance-free batteries (Fig. 2) are as the name applies, totally maintenance free and have no removable battery cell caps. Water never needs to be added to the maintenance-free battery. Battery is completely sealed, except for small vent holes in the cover. These vent holes allow what small amount of gases are produced in the battery to escape. Special chemical composition inside of battery reduces production of gas to an extremely small amount at normal charging voltages. Battery contains a visual test indicator which signals when an adequate charge level exists green indicator, when charging is required red or black or when replacement is required yellow. Battery is of polypropylene construction.
The electronic distributor does not require periodic lubrication.
To assure correct adjustment of headlamp aiming, it is recommended that the headlamps be checked and, if necessary, 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 headlamp beam pattern and may cause unsafe night time driving conditions.
If a vehicle is to be loaded abnormally, such as for a vacation trip, or with a salesman�s products, the headlamp aiming should be checked and adjusted to serve the new conditions. Refer to �Exterior Lighting System,� Group 8, (This Service Manual) for adjusting procedures.
WARNING: TEST RESULTS SUBMITTED TO EPA HAVE SHOWN THAT LABORATORY ANIMALS DEVELOP SKIN CANCER AFTER PROLONGED CONTACT WITH USED ENGINE OIL. ACCORDINGLY, THE POTENTIAL EXISTS FOR HUMANS TO DEVELOP A NUMBER OF SKIN DISORDERS, INCLUDING CANCER, FROM SUCH EXPOSURE TO USED ENGINE OIL. CARE SHOULD BE TAKEN, THEREFORE, WHEN CHANGING ENGINE OIL, TO MINIMIZE THE AMOUNT AND LENGTH OF EXPOSURE TIME TO USED ENGINE OIL ON YOUR SKIN. PROTECTIVE CLOTHING AND GLOVES, THAT CANNOT BE PENETRATED BY OIL, SHOULD BE WORN. THE SKIN SHOULD BE THOROUGHLY WASHED WITH SOAP AND WATER, OR USE WATERLESS HAND CLEANER, TO REMOVE ANY USED ENGINE OIL. DO NOT USE GASOLINE, THINNERS, OR SOLVENTS.
For best performance and to provide for maximum protection of all engines for all types of operation, only those lubricants should be selected which:
(a) Conform to the requirements of the API classification �FOR SERVICE SF or SF/CC�.
(b) Have the proper SAE grade number for the expected ambient temperature range (Fig. 3).
SAE 5W-30, SF quality engine oil is preferred for use in 318 engines with 2BBL carburetors.
Lubricants which do not have both an SAE grade number and the proper Service classification on the container should not be used.
A new logo or symbol has recently been developed to aid the vehicle owner in the proper selection of engine oil.
This logo (Fig.
4) is located on the oil container and is composed of three distinct areas for identifying various aspects of the oil.
(1) The top portion will indicate the quality of the oil, such as �SF�, �SF/CC�, or �SF/CD�.
(2) The center portion, to be used by most oil marketers, will show the SAE viscosity grade of the oil, such as SAE 1OW-30.
(3) The lower portion will state �ENERGY CONSERVING� if so applicable to that oil. Energy conserving, when shown, indicates, that oil, offers fuel economy benefits in gasoline engines.
There are many engine oils currently available that could increase the fuel economy of your vehicle. They are marketed as Energy Conserving, Fuel Saving, Fuel Efficient, Gas Saving, etc. Oils of this type are now identified on the lower portion of the new engine oil identification logo described above. In addition to selecting the proper API quality classification and SAE viscosity grade, use of energy conserving type engine oil is recommended.
Care should be taken in disposing of the used engine oil from your vehicle. Used oil, indiscriminately discarded, can present a problem to the environment. Contact your local dealer, service station, or governmental agency for advice on how and where used oil can be safely discarded in your area.
It is not necessary to add any material to crankcase oils for most types of vehicle operation. In some instances, such as, infrequent operation or short trips only and during break in after a major engine overhaul and/or new piston installation, addition of special materials containing antirust and antiscuff additives are beneficial. Engine Oil Supplement, Part Number 4318002, or equivalent, is a suitable product for this purpose.
Vehicles Equipped With High Performance V-B Engines
If the vehicle is to be used for maximum performance service (very high speed or very rapid acceleration), the engine requires heavier than normal lubricating oil. This is due to the high speeds, loads, and temperature of moving parts developed in these engines during this type of operation.
FOR BEST PROTECTION OF THE ENGINE UNDER THESE CONDITIONS, THE HEAVIEST AVAILABLE ENGINE OIL OF SF OR SF/CC QUALITY SHOULD BE USED THAT WILL PERMIT SATISFACTORY COLD STARTING. SAE 30 AND SAE 40 ARE RECOMMENDED. MULTI-VISCOSITY OILS SAE 20W-40 AND SAE 20W-50 MAY ALSO BE USED. ADDITIONAL ENGINE PROTECTION CAN BE ACHIEVED THROUGH THE USE OF CERTAIN ADDITIVES. MOPAR ENGINE OIL SUPPLEMENT, PART NUMBER 4318002 OR EQUIVALENT, PROVIDES ADDITIONAL WEAR AND SCUFF PROTECTION.
When outside temperatures are consistently below 32�F (0�C), SAE 1OW-30 or SAE 10-40 are recommended for ease in cold starting. However, even in cold weather, these grades should not be used if the vehicle is driven in competition or other forms of maximum performance operation.
The engine oil should be changed at the following intervals:
Every 12 months or 7,500 miles (12,000 km) whichever occurs first.
Every 3 months or 3,000 miles (4,800 km), whichever occurs first, if the vehicle is driven under any of the following operating conditions:
� Frequent driving in dusty conditions.
� Frequent trailer pulling.
� Extensive idling.
� Frequent short trip driving (less than 10 miles; 16 km) at temperatures below + 10�F (�12�C).
� More than 50% operation at sustained speeds over 70 miles per hour (112 km/h) during hot weather (above + 90�F; + 32�C).
Normal Driving - The oil filter should be replaced with a new filter at every second oil change. If mileage is less than 7,500 miles each 12 months replace oil filter at each oil change.
Severe Service - For severe operating conditions as outlined above, the oil filter should be replaced every second oil change.
Fleet Service (Police, Taxi, Limousine)
For police and limousine vehicles used primarily for highway type service (police highway patrol operation or limousine service of 25 miles (40 km) or more between stations) oil should be changed every six months or 5,000 miles (8,000 km), whichever occurs first. For vehicles operating at sustained high speeds during hot weather (above + 90�F) the engine oil should be changed every three months or 3,000 miles (4,800 km), whichever occurs first. For police, taxi, and limousine vehicles used primarily for urban type operation which usually involves short trip operation and prolonged or frequent periods of idling, oil should be changed every three months or 3,000 miles (4,800 km), whichever occurs first. Change oil filter at every second oil change.
Cars should be driven moderately during the first 300 miles. Speeds up to 50 to 55 mph (80 to 88 km/h) are desirable. While cruising, brief full throttle accelerations contribute to a good break in. Wide-open throttle accelerations in low gear can be detrimental and should be avoided.
The crankcase oil installed in the engine at the factory is a high quality energy conserving type lubricant. Oil changes should be consistent with anticipated climate conditions under which vehicle operation will occur. The recommended SAE viscosity grades are shown on the viscosity grade chart (Fig. 5). Only oils with the �For Service SF or SF/CC� classification should be used when adding or changing the crankcase engine oil. NON-DETERGENT OR STRAIGHT MINERAL OILS MUST NEVER BE 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 consume 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.
All Chrysler Corporation Engines are equipped with full flow throwaway oil filters (Fig. 6). This type of filter is recommended as a replacement filter in service on all vehicles.
The quality of replacement filters varies considerably. Only high quality filters should be used to assure most efficient service. MOPAR Engine Oil Filters, Part Number 3549957 or L-19 or equivalent, is a high quality filter and is recommended.
Under normal driving conditions it is recommended that the carburetor air filter be replaced every 52,500 miles (84,000 km). If however, the vehicle is driven frequently under dusty conditions, the filter element (Fig. 7) should be inspected periodically (at least every 15,000 miles (24,000 km)) and replaced if required.
At the mileage interval indicated on the maintenance chart, inject MOPAR Combustion Chamber Conditioner Part Number 4318001 or equivalent, into both ends of the choke valve shaft where it passes through the air horn to prevent the choke sticking from gum deposits on the shaft (Fig. 8). At same time, move choke shaft back and forth to distribute the solvent.
Also, apply same type of cleaner to fast idle cam and pivot pin to remove dirt, oil and any other deposits that may have collected and cause sticking or erratic motion.
Plugging of the fuel filter (Fig. 9), can be caused by contaminants in the fuel and may limit the speed at which a vehicle can be driven and cause hard starting.
If these conditions occur, the filter should be replaced.
All models are equipped with a closed crankcase ventilation system (Fig. 10). This system consists of a crankcase PCV valve mounted on the cylinder head cover, with a hose extending from the valve to the base of the carburetor.
A closed engine oil crankcase inlet air (filter)
cleaner with a hose connecting it to the carburetor air cleaner housing provides the sources of
air for the system. Refer to Group 25 for service RY345 procedure.
Proper operation of this system depends on freedom from sticking or plugging due to deposits. As vehicle mileage builds up, the PCV valve and passages may accumulate deposits. If valve is plugged or sticking, replace with a new valve - Do not attempt to clean the old PCV valve!
Check ventilation hose for indication of damage or plugging deposits. Replace, if necessary.
It is recommended that the crankcase inlet air (filter) cleaner be cleaned and relubricated every 52,500 miles (84,000 km).
Remove the crankcase inlet air filter (Fig. 11) and wash it thoroughly in kerosene, or similar solvent. Lubricate or wet the filter, by inverting the crankcase inlet air cleaner and filling with SAE-30 engine oil. Position the air cleaner to allow excess oil to drain thoroughly through the vent nipple. More frequent service may be necessary for vehicles operated extensively on short run, stop and go, or extended engine idle service.
Variables such as type of vehicle service, geographic area of vehicle operation and length of exposure time to heat and contaminants are factors affecting the life of rubber and plastic components. To provide best vehicle performance and avoid adverse effect on components life, it is recommended that the following components (unless otherwise noted) be inspected when performing other under-hood services. Components should be replaced immediately if there is any evidence of degradation that could result in failure.
Hoses (Also see Brake Hoses)
Inspect surface of hoses for evidence of heat and mechanical damage. Hard and brittle rubber, cracking, checking, tears, cuts, abrasion and excessive swelling indicate deterioration of the rubber.
Particular attention should be made to examining those hose surfaces nearest to high heat sources, such as the exhaust manifold.
Insure nylon tubing in these areas has not melted or collapsed. If the outer protective plastic sheath is damaged, the interior tubing must be inspected for possible damage.
Inspect hose routing to insure hose does not come in contact with any heat source or moving component which will cause heat damage or mechanical wear.
Inspect all hose connections such as clamps and couplings to make sure they are secure and no leaks are present. If a fluid leak is found, make sure that all hose clamps are installed correctly before assuming that the hose is responsible for the leak. In many instances, fluids such as oil, power steering fluid, and brake fluid are used during assembly plant operations to aid in the assembly of hoses to couplings. Therefore, oil wetness at the hose-coupling area is not necessarily an indication of leakage. Actual dripping of hot fluid when systems are under pressure (during vehicle operation), should be noted before hose is replaced based on leakage.
Inspect the connecting fasteners between the block and the engine mount bracket and those holding the mount to the frame for correct torque as specified in Group 9 (Engine). The rubber in the mount should be inspected for excessive softening, swelling, and/or gumminess caused by oil and/or gasoline contamination. Slight surface deterioration and wear at the ends will not adversely affect performance. If however excessive engine movement, rubber softening or swelling, or noise caused by metal to metal contact is observed, the engine mount assembly should be replaced.
CAUTION: AVOID CONTINUOUS CONTAMINATION WITH OIL OR GASOLINE. SUCH CONTAMINATION WILL RESULT IN REDUCED ENGINE MOUNT LIFE.
Upper and Lower Control Arm Bushings
Upper and lower control arm bushings should be inspected for off center condition of inner metal in relation to outer metal. Total failure is evident by excessive movement within bushing and noise caused by metal-to-metal contact. Small cracks in outer non-confined rubber does not constitute failure.
Lower control arm bushings may be visually inspected by lifting the car on a hoist and inspecting from underneath. Upper control arm bushings may be inspected by removing the front wheels. If failure exists, replace bushings as recommended. See Group 2, �Front Suspension�.
Exhaust System Rubber Isolator and Loop-Type Hanger
Inspect surface for rubber-to-metal separation or deep cracks. Slight cracking due to weathering and ozone do not adversely effect performance. If however, excessive deep localized cracks are present, or any part of the exhaust system abnormally contacts the underbody or underbody hardware, the isolator and/or hanger should be adjusted or replaced.
Splash Shield�Front Fender to Upper Control Arm
Inspect the engine side surface of splash shields for heat degradation, cracking, tearing and mechanical damage. Particular attention should be made to examining the surface nearest to high heat sources, such as exhaust manifold. Excessive heat degradation requires splash shield replacement and upper control arm bushing inspection.
Valve Cover Gaskets
Inspect the area around the perimeter of the valve cover where it contacts the engine head for evidence of oil seepage. If oil seepage is apparent, the valve cover gasket or seal should be replaced.
Inspect all drive belts for evidence of cuts and cracks and replace, if necessary. Check routing to make sure there is no interference between the belt and other engine components. Check belts for proper tension and adjust, if necessary, according to the specifications outlined in Group 7, �Cooling�.
Power Steering (Pump and Reservoir)
CAUTION: FLUID LEVELS SHOULD BE CHECKED WITH THE ENGINE OFF TO PREVENT INJURY FROM MOVING PARTS. DO NOT OVERFILL. DO NOT USE AUTOMATIC TRANSMISSION FLUID.
When performing other underhood services, the power steering fluid level should be checked at the power steering pump reservoir. Before removing the reservoir cap, wipe the outside of the cap and reservoir so that no dirt can fall into the reservoir. All power steering pumps on Chrysler Corporation cars are equipped with a dipstick (Fig. 12). Fluid level should be maintained at the proper level indicated on the dipstick. If necessary, add fluid to restore to the proper indicated level. Only petroleum fluids specially formulated for minimum effect on the rubber hoses should be used. Power Steering Fluid (Part Number 4318055, or equivalent) is material of this type and is recommended.
Front Suspension Ball Joints�Inspection
All models have two upper and two lower front suspension ball joints (Fig. 13) that require periodic servicing. These ball joints should be inspected whenever a car is serviced for other reasons. Damaged joints or seals should be replaced to prevent leakage or contamination of the grease. Ball joints should also be replaced when the end play exceeds the specifications outlined in �FRONT SUSPENSION� Group 2.
Ball joints are semipermanently lubricated at the factory with a special grease. When lubricating ball joints use only a special long life chassis grease intended for this purpose such as MOPAR Multimileage Lubricant, Part Number 4318062, or equivalent.
Frequency of Lubrication
(1) Normal Service.
Lubricate every three years or 30,000 miles (48,000 km), whichever occurs first.
(2) Severe Service (Police, Taxi, Limousine, Trailer Tow).
Lubricate every eighteen months or 15,000 miles (24, 000 km), whichever occurs first.
(1) Clean the accumulated dirt and grease from the outside surface of the seal to permit complete inspection.
(2) Wipe off the outside surface of the grease fitting to remove accumulated dirt from the grease inlet area to avoid grease contamination during relubrication.
(3) Fill and flush the joints with lubricant. Stop filling when grease begins to flow freely from the bleed area at the base of the seal, or if the seal begins to balloon.
(4) Wipe off any excess grease from exterior surface of ball joint and adjacent component surfaces.
All models have four tie rod end ball joints and a pitman arm joint that require periodic servicing (Fig. 14).
These should be inspected whenever the car is serviced for other reasons. Damaged joints or seals should be replaced to prevent leakage or contamination of the grease.
The tie rod ends and pitman arm are semipermanently lubricated at the factory with a special grease. When relubricating the steering linkage, use only special long life chassis grease intended for this purpose such as MOPAR Multimileage Lubricant, Part Number 4318062 or equivalent.
Frequency of Lubrication
(1) Normal Service
Lubricate every three years or 30,000 miles (48,000 km), whichever occurs first.
(2) Severe Service (Police, Taxi, Limousine, Trailer Tow)
Lubricate every eighteen months or 15,000 miles (24,000 km), whichever occurs first.
(1) Clean the accumulated dirt and grease from the outside surface of the seal to permit complete inspection.
(2) Wipe off the outside of the grease fitting to remove accumulated dirt from the grease inlet area, to avoid grease contamination during relubrication.
(3) Fill and flush the joints with lubricant. Stop filling when grease begins to flow freely from the bleed area at the base of the seal, or if the seal begins to balloon.
(4) Wipe off any excess grease from the exterior surfaces of joints and adjacent component surfaces.
AXLE IDENTIFICATION CHART
|7-1/4||Cover||2.5||2.5||Bottom of Filler Hole to 1/4 inch (6.4 mm) Below|
|8-1/4||Cover||3.0||4.4||Bottom of Filler Hole to 1/4 inch (6.4 mm) Below|
Chrysler Corporation recommends that Multipurpose Gear Lubricant, as defined by the American Petroleum Institute GL-5, should be used in all rear axles. MOPAR Hypoid Lubricant (Part Number 4318058) or equivalent is an oil of this type and is recommended.
If a fluid replacement becomes necessary on vehicles equipped with a Sure-Grip differential, it is recommended that only MOPAR Hypoid Lubricant be used. In addition, Sure-Grip differentials require the use of MOPAR Hypoid Gear Oil Additive-Friction Modifier, Part No. 4318060. This material should be added to MOPAR Hypoid Lubricant whenever a fluid change is made in a Sure-Grip axle.
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 recommended in vehicles where operation is classified as normal passenger car service.
The only exceptions, however, would be where the lubricant has been contaminated with water, or to provide the correct viscosity grade for the anticipated temperature range.
If necessary to change lubricant in the axle remove old lubricant with suction pump through filler plug hole (Fig. 15).
Trailer Towing and/or Severe Service
For trailer tow, taxi, police and limousine type service, the lubricant should be drained and axle refilled with the specified lubricant every 36,000 miles (58, 000 km).
CAUTION: Insure that rubber (�Press in Type�) filler plug is fully seated in axle cover after lubricant change or level inspection.
Fluid Level Check
For normal passenger car service, periodic fluid level checks are not required. At each engine oil change however, the exterior surfaces of the axle assembly should be inspected for evidence of gear oil leakage. Perform a fluid level check (described under �a� or �b�) to confirm any suspected leakage.
(a) With car in a level position, supported by the suspension (on an axle or wheel type hoist or on the ground) the fluid level for the axle should be as described in the �Axle Identification Chart�.
(b) With the axle hanging free (on frame contact hoist) the lubricant level for ALL models should not be lower than the bottom of the filler plug hole.
It is important that the transmission fluid be maintained at the level prescribed.
Selection of Lubricant
Use only fluids of the type labeled DEXRON II automatic Transmission Fluid. MOPAR DEXRON II (P/N 4271243), or MOPAR ATF PLUS (P/N 4318077) automatic transmission fluids or equivalent is recommended.
Chrysler Corporation does not recommend the addition of any fluids to the transmission other than those from the automatic transmission fluids listed above. Exceptions to this policy are the uses of special dyes to aid in detecting fluid leaks. The use of transmission sealers should be avoided since they may adversely affect seals.
The fluid level in the automatic transmission should be checked when performing other underhood services. Operation with an improper fluid level will greatly reduce the life of the transmission and of the fluid.
When the fluid level is checked, especially on vehicles operated under conditions of severe service, the condition of the fluid should be observed. If severe darkening of the fluid, accompanied by a strong odor is noted, the fluid and filter should be changed and the bands adjusted. A physical change in the fluid such as this may be the result of overheating, such as is possible in severe service or if the vehicle is equipped with a non-factory installed air conditioning unit, resulting in fluid break down.
Fluid Level Check
To properly check the automatic transmission fluid level, the following procedure must be used:
CAUTION: To prevent dirt and water from entering the transmission after checking or replenishing fluid, make certain that the dipstick cap is reseated properly.
(1) Vehicle must be on level ground.
(2) Engine should be running at curb idle speed.
(3) Apply parking brake fully.
(4) Place gear selector momentarily in each gear position, ending with the lever in N (Neutral).
(5) Remove dipstick and determine if fluid is hot or warm. Hot fluid is approximately 180�F (82�C), which is the normal operating temperature after the vehicle has been driven at least 15 miles. The fluid cannot comfortably be held between the finger tips. Warm is when fluid is between 85 and 125�F (29 and 52�C).
(6) Wipe dipstick clean and reinsert until cap seals, remove and note reading (Fig. 16).
(a) If the fluid is hot, the reading should be in the crosshatched area marked OK.
(b) If the fluid is warm, the fluid level should be between the two dimples.
If the fluid level checks low, add sufficient fluid to bring the level to within the marks indicated for the appropriate temperature.
Fluid and Filter Changes
Fluid and filter changes or band adjustments are not recommended for normal passenger car usage.
Severe usage as defined below, requires that fluid and filter be changed and bands adjusted every 15,000 miles (24,
(1) More than 50% operation in heavy city traffic during hot weather (above 90�F; 32�C).
(2) Police, Taxi, Limousine, Commercial Type Operation, Trailer Tow.
(1) When the factory fill fluid is changed as recommended above, only fluids of the type labeled DEXRON II Automatic Transmission Fluid should be used. A band adjustment and filter change should be made at the time of the oil change.
(2) If the transmission is disassembled for any reason, the fluid and filter should be changed, and the bands adjusted. See Transmission, Group 21 for details.
The torque converter is not equipped with a drain plug and no attempt should be made to drain it while changing the filter and fluid.
(1) Raise vehicle on a hoist. Place a drain container with large opening under transmission oil pan.
(2) Loosen pan bolts at one corner, tap the pan to break it loose allowing it to drain, then remove the pan.
If necessary, adjust the reverse band, see Transmission, Group 21.
The installation of a new filter on bottom of the valve body is recommended. Tighten filter retaining screws to 35 inch-pounds (4 N�m).
(3) Clean the oil pan and reinstall using a new gasket. Tighten oil pan bolts to 150 inch pounds (17 N�m) torque.
(1) Pour approximately two quarts (1.9 liters) of DEXRON II Automatic Transmission Fluid through the filler tube.
(2) With engine idling in neutral, add enough fluid to bring level to between the two dimples (approximately one pint, 0.47 liter).
(3) Allow engine to idle at least two minutes. Slowly shift transmission through all gears, pausing momentarily at each position, ending in the neutral position, and recheck.
(4) Add fluid to bring level to between the two dimples on the oil level indicator. Make sure oil level indicator properly sits on filler tube to prevent dirt from entering transmission.
When transmission fluid level is established warm between the two dimples the fluid level will be at the �OK� mark when the transmission reaches normal operating temperature (approximately 180�F; 82�C).
The fluid in the master cylinder should be checked when performing other under hood services (Fig. 17).
If necessary, add fluid to bring level to the bottom of the split rings. With disc brakes, fluid level can be expected to fall as the brake pads wear. However, low fluid level may be caused by a leak and a checkup may be needed. Only brake fluid conforming to MVSS116, DOT 3 should be used. MOPAR Brake Fluid is a fluid of this quality and is recommended to provide best brake performance. Use of a brake fluid other than one conforming to MVSS 116, DOT 3, may result in sudden brake failure during hard prolonged braking. Use only brake fluid that has been stored in a tightly closed container, to avoid contamination with foreign matter or moisture.
CAUTION: DO NOT ALLOW PETROLEUM BASE FLUID TO CONTAMINATE THE BRAKE FLUID - SEAL DAMAGE WILL RESULT!
Inspection of brake hoses should be performed whenever the brake system is serviced and every 7,500 miles (12,000 km) or 12 months, whichever occurs first (every engine oil change). The hoses should be checked for:
(1) Correct length, severe surface cracking, pulling scuffing or worn spots. (Should the fabric casing of the hose be exposed by cracks or abrasions in the rubber hose cover, the hose should be replaced). Eventual deterioration of the hose can take place with possible burst failure.
(2) Faulty installation to cause twisting, wheel, tire, or chassis interference.
The front and rear universal joints on all models (Figs. 18 and 19) should be inspected periodically for external leaks or damage. If external leaks or damage is evident, the universal joint should be replaced. Relubrication is not recommended.
The lubricant in the front wheel bearings should be inspected whenever the rotors 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 resurfaced.
For severe service vehicles, (such as taxi and police vehicles involving frequent or continuous brake application) wheel bearings should be inspected whenever the rotors are removed to inspect or service the brake system. Clean and repack the bearings, with a high temperature wheel bearing grease whenever brake pads or linings are replaced, or at least every 9,000 miles (14 000 km), whichever occurs first.
Check lubricant to see that it is adequate in quantity and quality. If the grease is low in quantity, contains dirt, appears dry or has been contaminated with water to produce a milky appearance, the bearings should be cleaned and repacked. DO NOT ADD GREASE TO THE WHEEL BEARINGS. RELUBRICATE COMPLETELY. MIXING OF DIFFERENT TYPES OF GREASES IN WHEEL BEARINGS SHOULD BE AVOIDED SINCE IT MIGHT RESULT IN EXCESSIVE THINNING AND LEAKAGE OF THE GREASE.
Discard the old seal. Thoroughly clean the old lubricant from the bearings and from the hub cavity (Fig. 20). Inspect the rollers for signs of pitting or other surface distress. Light bearing discoloration should be considered normal. Bearings must be replaced if any defects exist. Repack the bearings with a High Temperature Multipurpose E.P. Grease, MOPAR Front Wheel Bearing Grease (High Temperature) Part Number 4318064 or equivalent is a grease of this type and is recommended for normal and severe service. Use of a bearing packer is recommended. A small amount of new grease should also be added to the hub cavity.
(1) Install hub assembly on spindle.
(2) Install outer bearing, thrust washer and nut (Fig. 21).
(3) Tighten wheel bearing adjusting nut to 240300 inch-pounds (27 to 34 N�m) while rotating hub. This seats the bearings.
(4) Back off adjusting nut 1/4 turn (90�), then tighten adjusting nut finger tight.
(5) Position lock on nut with one pair of slots in line with cotter pin hole. Install cotter pin.
(6) Install grease cap and wheel and tire assemblies. Tighten wheel stud nuts to 85 foot-pounds (115 N�m) on all models. Install wheel covers.
Lubrication of speedometer cable is not required. For service of noisy or erratic operation of cable see �Electrical,� Group 8.
Every 12 months the accelerator linkage components should be wiped clean of all accumulated dust and dirt and relubricated with Multipurpose Grease, NLGI Grade 2 E.P.; such as MOPAR Multimileage Lubricant, Part Number 4318062 or equivalent, as described below. Do not lubricate ball joints or throttle control cable.
On police and taxi vehicles so equipped, hand operated throttle controls should be checked and lubricated once a year. Multi-Purpose Grease, NLGI Grade 2, EP, should be applied to the pivot bearing areas between the fast idle adjusting lever and lever bracket.
Apply a thin film of the prescribed lubricant to the upper and lower bellcrank pivot areas (Fig. 22).
PARTS REQUIRING NO LUBRICATION
(back to CONTENTS)
There are many points that should not be lubricated, some because they are permanently lubricated, some because lubricants will be detrimental to their operating characteristics, and some because lubricants will cause component failures. In any event, rubber bushings should not be lubricated, not only because lubricants will cause rubber to fail, but also will destroy their necessary friction characteristics. The following parts should not be lubricated.
Fan Belt Idler Pulley
Idler Arm Assembly
Rear Wheel Bearings
Throttle Control Cable
Throttle Linkage Ball Joints
TorqueFlite Selector Linkage
Upper and Lower Control Arm Bushings
Water Pump Bearings
Body and other operating mechanisms should be inspected, cleaned, and lubricated as required to maintain ease of operation and to provide protection against rust and wear.
Prior to applying any lubricant, wipe the parts clean to remove dust and grit. After lubricating parts, remove excess oil or lubricant.
Relubricate mechanisms as outlined in the following paragraphs. Where Spray White Lubricant is specified, use MOPAR Spray White Lubricant, Part Number 4318066 or equivalent, is suitable lubricant.
When performing other underhood service, the hood latch, release mechanism, and safety catch should be inspected, cleaned, and lubricated. It is important that proper lubrication be maintained to insure that the hood mechanisms function properly and safely. Multipurpose lubricant NLGI Grade 2 should be applied sparingly to all pivot and sliding contact areas. (Fig. 23).
Apply engine oil to all link or hinge pivots and MOPAR Spray White Lubricant, or equivalent, to gear teeth and sliding contact areas (Fig. 24).
On all hinges, apply engine oil to hinge pin ends (Fig. 25). On lower hinges, in addition, apply engine oil to spring ends and contact areas.
CAUTION: Avoid lubricant on roller surfaces of hinge arm and roller on front and rear door hinges.
When necessary, apply a thin film of Spray White Lubricant or equivalent, directly to key. Insert key into lock and actuate several times. Wipe excess lubricant from key.
Particular attention should be given to external lock cylinders during fall and winter months to insure protection from water and ice.
Apply light engine oil, sparingly, to door latch and Spray White Lubricant or equivalent, to contact area of striker bolt.
If necessary to inspect operation of and relubricate these parts, remove door trim panel. Apply a film of MOPAR Spray White Lubricant or equivalent, to all link end pivots (Fig. 26).
If necessary to inspect operation of and relubricate these parts, remove door or quarter trim panel. Apply MOPAR Spray White Lubricant or equivalent, sparingly, to regulator sector gear teeth, assist spring and pivots. Apply same lubricant sparingly, to glass lower frame roller slide tracks and roller and bracket assembly pivot points (Fig. 27).
Apply MOPAR Spray White Lubricant or equivalent, sparingly, to all pivot and sliding contact surfaces (Fig. 28).
Apply Spray White Lubricant or equivalent, sparingly, to all torsion bar support bearing areas. (Fig. 29). Apply engine oil to counter balance pivots and Multipurpose Lubricant to prop (pivots) and slides.
Apply Multipurpose Lubricant, NLGI grade 2 EP, or MOPAR Multimileage Lubricant, Part Number 4318064 or equivalent, sparingly, to all pivot areas.
Special care should be taken when raising the vehicle on a frame contact type hoist. The hoist must be equipped with the proper adapters in order that the vehicle will be supported in the correct locations (Fig. 30).
Conventional hydraulic hoists may be used after determining that the adapter plates will make firm contact with the lower control arms and the rear axle housing.
A regular floor jack may be used under the rear axle housing or under the front suspension lower control arms (Fig. 30).
(1) When lifting from rear axle housing do not allow jack lifting plate fingers to contact axle cover plate.
(2) A floor jack must never be used on any parts of the underbody.
(3) Do not attempt to raise one entire side of the vehicle by placing a jack midway between front and rear wheels. This practice may result in permanent damage to the body.
Jack receptacles are located at the body sills to accept the scissors jack supplied with the vehicle for emergency road service. Always block opposite wheels and jack on level surface. DO NOT USE REGULAR FLOOR JACK TO LIFT VEHICLE AT THESE LOCATIONS.
Figure 31 shows the recommended Hook-up per canine.
