PARTS & LUBRICATION RECOMMENDATIONS

GEAR LUBRICANTS

SAE ratings also apply to multigrade gear lubricants. In addition, API classification defines the lubricant's usage, such as API GL-5 and SAE 75W-90.

AXLE

Note. DaimlerChrysler recommends using Mopar® lubricants or lubricants of equal quality.

FRONT AXLE

1. 200MM - Mopar® Synthetic Gear Lubricant 75W-140

REAR AXLE

1. 213MM - Mopar® Synthetic Gear Lubricant 75W-140

Note. ELSD equipped axles require 118 ml (4 ounces) of Limited Slip Additive be added to the lubricant.

ENGINE OIL-GASOLINE ENGINES

When service is required, DaimlerChrysler Corporation recommends that only Mopar® brand parts, lubricants and chemicals be used. Mopar® provides the best engineered products for servicing DaimlerChrysler Corporation vehicles.

Only lubricants bearing designations defined by the following organization should be used.

1. Society of Automotive Engineers (SAE)
2. American Petroleum Institute (API)
3. National Lubricating Grease Institute (NLGI)
4. Association des Constructeurs Europeens d' Automobiles (European Automobile Manufacturers Association) (ACEA)

API SERVICE GRADE CERTIFIED

Use an engine oil that is API Certified. MOPAR® provides engine oils, that meet or exceed this requirement.

Scheme 3

An SAE viscosity grade is used to specify the viscosity of engine oil. Use only engine oils with multiple viscosities such as 5W-20 or 5W-30. These are specified with a dual SAE viscosity grade which indicates the cold-to-hot temperature viscosity range. For 3.7L/4.7L engines SAE 5W-20 engine oil is recommended for all operating temperatures. For 5.7L engines, SAE 5W-20 engine oil is recommended for all operating temperatures. Vehicles with 5.7L engines equipped with Multiple Displacement System, (MDS), must use SAE 5W-20 oil. Failure to do so may result in improper operation of the Multiple Displacement System (MDS). These engine oils improve low temperature starting and vehicle fuel economy. Refer to your engine oil filler cap for the recommended engine oil viscosity for your vehicle.

ACEA Categories

For countries that use the ACEA European Oil Categories for Service Fill Oils, use engine oils that meet the requirements of ACEA A1/B1, A2/B2, or A3/B3.

ENERGY CONSERVING OIL

An Energy Conserving type oil is recommended for gasoline engines. The designation of ENERGY CONSERVING is located on the label of an engine oil container.

Scheme 4

Standard engine oil identification notations have been adopted to aid in the proper selection of engine oil. The identifying notations are located on the front label of engine oil plastic bottles and the top of engine oil cans.

This symbol means that the oil has been certified by the American Petroleum Institute (API). DaimlerChrysler only recommends API Certified engine oils. Use Mopar® engine oil or equivalent.

SYNTHETIC ENGINE OILS

There are a number of engine oils being promoted as either synthetic or semi-synthetic. If you chose to use such a product, use only those oils that meet the American Petroleum Institute (API) and SAE viscosity standard. Follow the service schedule that describes your driving type.

ENGINE OIL ADDITIVES/SUPPLEMENTS

The manufacturer does not recommend the addition of any engine oil additives/supplements to the specified engine oil. Engine oil additives/supplements should not be used to enhance engine oil performance. Engine oil additives/supplements should not be used to extend engine oil change intervals. No additive is known to be safe for engine durability and can degrade emission components. Additives can contain undesirable materials that harm the long term durability of engines by

1. Doubling the level of phosphorus in the engine oil. The ILSAC (International Lubricant Standard Approval Committee) GF-2 and GF-3 standards require that engine oil contain no more than 0.10% phosphorus to protect the vehicles emissions performance. Addition of engine oil additives/supplements can poison, from the added sulfur and phosphorus, catalysts and hinder efforts to guarantee emissions performance to 80,000 miles.
2. Altering the viscosity characteristics of the engine oil so that it no longer meets the requirements of the specified viscosity grade.
3. Creating potential for an undesirable additive compatibility interaction in the engine crankcase. Generally it is not desirable to mix additive packages from different suppliers in the crankcase; there have been reports of low temperature engine failures caused by additive package incompatibility with such mixtures.

A/C REFRIGERANT

The refrigerant used in this air conditioning system is a HydroFluoroCarbon (HFC), type R-134a. Unlike R-12, which is a ChloroFluoroCarbon (CFC), R-134a refrigerant does not contain ozone-depleting chlorine. R-134a refrigerant is a non-toxic, non-flammable, clear and colorless liquefied gas.

The A/C refrigerant system is filled-for-life at the factory and requires no regular maintenance. Although not required at specific intervals, the charge level should be checked if system performance deteriorates or if a noise or leak is suspected. Refer to DIAGNOSIS AND TESTING .

ETHYLENE-GLYCOL MIXTURES

The required ethylene-glycol (antifreeze) and water mixture depends upon the climate and vehicle operating conditions. The recommended mixture of 50/50 ethylene-glycol and water will provide protection against freezing to -37° C (-35° F). The antifreeze concentration must always be a minimum of 44 percent, year-round in all climates. If percentage is lower than 44 percent, engine parts may be eroded by cavitation, and cooling system components may be severely damaged by corrosion. Maximum protection against freezing is provided with a 68 percent antifreeze concentration, which prevents freezing down to -67.7° C (-90° F). A higher percentage will freeze at a warmer temperature. Also, a higher percentage of antifreeze can cause the engine to overheat because the specific heat of antifreeze is lower than that of water.

Use of 100 percent ethylene-glycol will cause formation of additive deposits in the system, as the corrosion inhibitive additives in ethylene-glycol require the presence of water to dissolve. The deposits act as insulation, causing temperatures to rise to as high as 149° C (300° F). This temperature is hot enough to melt plastic and soften solder. The increased temperature can result in engine detonation. In addition, 100 percent ethylene-glycol freezes at 22° C (-8° F).

PROPYLENE-GLYCOL MIXTURES

It's overall effective temperature range is smaller than that of ethylene-glycol. The freeze point of 50/50 propylene-glycol and water is -32° C (-26° F). 5° C higher than ethylene-glycol's freeze point. The boiling point (protection against summer boil-over) of propylene-glycol is 125° C (257° F ) at 96.5 kPa (14 psi), compared to 128° C (263° F) for ethylene-glycol. Use of propylene-glycol can result in boil-over or freeze-up on a cooling system designed for ethylene-glycol. Propylene glycol also has poorer heat transfer characteristics than ethylene glycol. This can increase cylinder head temperatures under certain conditions.

Propylene-glycol/ethylene-glycol mixtures can cause the destabilization of various corrosion inhibitors, causing damage to the various cooling system components. Also, once ethylene-glycol and propylene-glycol based coolants are mixed in the vehicle, conventional methods of determining freeze point will not be accurate. Both the refractive index and specific gravity differ between ethylene glycol and propylene glycol.

TRANSFER CASE

Recommended lubricant for the NV140 transfer case is Mopar® ATF+4, Automatic Transmission Fluid. Recommended lubricant for the NV245 transfer case is Mopar® NV245/247 Transfer Case Fluid.

ENGINE OIL-DIESEL ENGINE

When service is required, DaimlerChrysler Corporation recommends that only Mopar ® brand parts, lubricants and chemicals be used. Mopar ® provides the best engineered products for servicing Chrysler LLC vehicles.

Only lubricants bearing designations defined by the following organization should be used.

1. Society of Automotive Engineers (SAE)
2. American Petroleum Institute (API)
3. National Lubricating Grease Institute (NLGI)
4. Association des Constructeurs Europeens d' Automobiles (European Automobile Manufacturers Association) (ACEA)

Use an engine oil that is API Certified. Mopar ® provides Synthetic engine oils, that meet or exceed this requirement.

SAE VISCOSITY GRADE

An SAE Synthetic engine oil that conforms to ACEA A3/B4/C3 that is approved to MB 229.31 is recommended for all operating temperatures. This engine oil is a low ash product that improves low temperature starting and vehicle fuel economy.

DISPOSING OF USED ENGINE OIL

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 authorized dealer, service station, or governmental agency for advice on how and where used oil can be safely discarded in your area.

The manufacturer does not recommend the addition of any engine oil additives/supplements to the specified engine oil. Engine oil additives/supplements should not be used to enhance engine oil performance. Engine oil additives/supplements should not be used to extend engine oil change intervals. No additive is known to be safe for engine durability and can degrade emission components. Additives can contain undesirable materials that harm the long term durability of engines by

2. Altering the viscosity characteristics of the engine oil so that it no longer meets the requirements of the specified viscosity grade.
3. Creating potential for an undesirable additive compatibility interaction in the engine crankcase. Generally it is not desirable to mix additive packages from different suppliers in the crankcase; there have been reports of low temperature engine failures caused by additive package incompatibility with such mixtures.

DIESEL FUEL

Diesel fuels are available from most reputable fuel marketers. Fuel with a calculated Cetane Index of 45 or higher must be used. See your authorized dealer or distributor for further information regarding fuels availability.

In areas where diesel fuel is below the recommended quality levels (high levels of sulfur and water) it is critical to monitor the fuel filter for contamination and the "Water-In-Fuel" message in the Electronic Vehicle Information Center (EVIC). Failure to properly service the fuel system for these items can significantly reduce engine life and lead to major engine repair. More frequent service intervals of the fuel filter/water separator unit may be required under these conditions than those shown in " MAINTENANCE SCHEDULE A or B."

GAS ENGINES

The cooling system is designed around the coolant. The coolant must accept heat from engine metal, in the cylinder head area near the exhaust valves and engine block. Then coolant carries the heat to the radiator where the tube/fin radiator can transfer the heat to the air.

The use of aluminum cylinder blocks, cylinder heads, and water pumps requires special corrosion protection. Mopar® Antifreeze/Coolant, 5 Year/100,000 Mile Formula (MS-9769), or the equivalent ethylene glycol based coolant with hybrid organic corrosion inhibitors (called HOAT, for Hybrid Organic Additive Technology) is recommended. This coolant offers the best engine cooling without corrosion when mixed with 50% Ethylene Glycol and 50% distilled water to obtain a freeze point of -37°C (-35°F). If it loses color or becomes contaminated, drain, flush, and replace with fresh properly mixed coolant solution.

The green coolant MUST NOT BE MIXED with the orange or magenta coolants. When replacing coolant the complete system flush must be performed before using the replacement coolant.
