DESCRIPTION - POWER STEERING FLUID
Mopart ATF +4, Automatic Transmission Fluid is required in the power steering system. Substitute fluids can induce power steering system failure.
Mopart ATF +4, Automatic Transmission Fluid when new is red in color. The ATF is dyed red so it can be identified from other fluids used in the vehicle such as engine oil or antifreeze. The red color is not permanent and is not an indicator of fluid condition. As the vehicle is driven, the ATF will begin to look darker in color and may eventually become brown. This is normal. ATF+4 also has a unique odor that may change with age. Consequently, odor and color cannot be used to indicate the fluid condition or the need for a fluid change.
DESCRIPTION - ENGINE COOLANT
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 CONTAINERS. WASH SKIN AND CLOTHING THOROUGHLY AFTER COMING IN CONTACT WITH ETHYLENE GLYCOL. KEEP OUT OF REACH OF CHILDREN. DISPOSE OF GLYCOL BASE COOLANT PROPERLY, CONTACT YOUR DEALER OR GOVERNMENT AGENCY FOR LOCATION OF COLLECTION CENTER IN YOUR AREA. DO NOT OPEN A COOLING SYSTEM WHEN THE ENGINE IS AT OPERATING TEMPERATURE OR HOT UNDER PRESSURE, PERSONAL INJURY CAN RESULT. AVOID RADIATOR COOLING FAN WHEN
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.
Mopart
Antifreeze/Coolant,
The use of aluminum cylinder blocks, cylinder heads, and water pumps requires special corrosion protection. Year/100,000 Mile Formula (MS-9769), or the equiva- lent ethylene glycol base coolant with organic corro- sion 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 solu- tion.
MoparT
Antifreeze/Coolant,
CAUTION: Year/100,000 Mile Formula (MS-9769) may not be mixed with any other type of antifreeze. Mixing of coolants other than specified (non-HOAT or other HOAT), may result in engine damage that may not be covered under the new vehicle warranty, and decreased corrosion protection.
COOLANT PERFORMANCE
The required ethylene-glycol (antifreeze) and water mixture depends upon climate and vehicle operating conditions. The coolant performance of various mix- tures follows:
Pure Water-Water can absorb more heat than a mixture of water and ethylene-glycol. This is for pur- pose of heat transfer only. Water also freezes at a higher temperature and allows corrosion. 100 percent Ethylene-Glycol-The
corrosion inhibiting additives in ethylene-glycol need the pres- ence of water to dissolve. Without water, additives form deposits in system. These act as insulation causing temperature to rise to as high as 149°C (300°F). This temperature is hot enough to melt plas- tic and soften solder. The increased temperature can result in engine detonation. In addition, 100 percent ethylene-glycol freezes at -22°C (-8°F).
50/50 Ethylene-Glycol and Water-Is the recom- mended mixture, it provides protection against freez- ing to -37°C (-34°F). The antifreeze concentration
LUBRICATION & MAINTENANCE
0 - 4
FLUID TYPES (Continued)must always be a minimum of 44 percent, year- round in all climates. If percentage is lower, engine parts may be eroded by cavitation. Maximum protec- tion 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 per- centage of antifreeze can cause the engine to over- heat because specific heat of antifreeze is lower than that of water.
CAUTION: Richer antifreeze mixtures cannot be measured with normal field equipment and can cause problems associated with 100 percent ethyl- ene-glycol.
COOLANT SELECTION AND ADDITIVES
NOTE: Refer to the vehicle’s coolant bottle to iden- tify HOAT or Non-HOAT coolant. Non-HOAT coolant is green in color.
The use of aluminum cylinder blocks, cylinder heads and water pumps requires special corrosion protection. Only Mopart Antifreeze/Coolant, Year/100,000 Mile Formula (glycol base coolant with corrosion inhibitors called HOAT, for Hybrid Organic Additive Technology) is recommended. This coolant offers the best engine cooling without corrosion when mixed with 50% distilled water to obtain to obtain a freeze point of it loses color or becomes contaminated, drain, flush, and replace with fresh properly mixed coolant solution.

DESCRIPTION - AUTOMATIC TRANSMISSION FLUID
NOTE: Refer to Service Procedures in this group for fluid level checking procedures.
Mopart ATF +4, Automatic Transmission Fluid is the recommended fluid for DaimlerChrysler auto- matic transmissions.
Dexron II fluid IS NOT recommended. Clutch chatter can result from the use of improper fluid.
Mopart ATF +4, Automatic Transmission Fluid when new is red in color. The ATF is dyed red so it can be identified from other fluids used in the vehicle such as engine oil or antifreeze. The red color is not permanent and is not an indicator of fluid condition. As the vehicle is driven, the ATF will begin to look darker in color and may eventually become brown. This is normal. ATF+4 also has a unique odor that may change with age. Consequently, odor and color cannot be used to indicate the fluid condition or the need for a fluid change.
DR FLUID TYPES (Continued) FLUID ADDITIVES
DaimlerChrysler strongly recommends against the addition of any fluids to the transmission, other than those automatic transmission fluids listed above. Exceptions to this policy are the use of special dyes to aid in detecting fluid leaks.
Various “special†additives and supplements exist that claim to improve shift feel and/or quality. These additives and others also claim to improve converter clutch operation and inhibit overheating, oxidation, varnish, and sludge. These claims have not been sup- ported to the satisfaction of DaimlerChrysler and these additives must not be used. The use of trans- mission “sealers†should also be avoided, since they may adversely affect the integrity of transmission seals.
OPERATION - AUTOMATIC TRANSMISSION FLUID
The automatic transmission fluid is selected based upon several qualities. The fluid must provide a high level of protection for the internal components by providing a lubricating film between adjacent metal components. The fluid must also be thermally stable so that it can maintain a consistent viscosity through a large temperature range. If the viscosity stays con- stant through the temperature range of operation, transmission operation and shift feel will remain con- sistent. Transmission fluid must also be a good con- ductor of heat. The fluid must absorb heat from the internal transmission components and transfer that heat to the transmission case.
