ENGINE OIL
SAE VISCOSITY RATING INDICATES ENGINE OIL VISCOSITY
An SAE viscosity grade is used to specify the vis-
cosity of engine oil. SAE 30 specifies a single viscos-
ity engine oil. Engine oils also have multiple
viscosities. These are specified with a dual SAE vis-
cosity grade which indicates the cold-to-hot tempera-
ture viscosity range.
²SAE 30 = single grade engine oil.
²SAE 10W-30 = multiple grade engine oil.
API QUALITY CLASSIFICATION
The API Service Grade specifies the type of perfor-
mance the engine oil is intended to provide. The API
Service Grade specifications also apply to energy con-
serving engine oils.
Use engine oils that are API Service Certified.
5W-30 and 10W-30 MOPAR engine oils conform to
specifications.
Refer to Group 9, Engine for engine oil specifica-
tion.
GEAR LUBRICANTS
SAE ratings also apply to multiple grade gear
lubricants. In addition, API classification defines the
lubricants usage.LUBRICANTS AND GREASES
Lubricating grease is rated for quality and usage
by the NLGI. All approved products have the NLGI
symbol (Fig. 3) on the label. At the bottom NLGI
symbol is the usage and quality identification letters.
Wheel bearing lubricant is identified by the letter
ªGº. Chassis lubricant is identified by the latter ªLº.
The letter following the usage letter indicates the
quality of the lubricant. The following symbols indi-
cate the highest quality.

To assure of properly formulated engine oils, it is
recommended that SAE Grade 5W-30 engine oils that
meet Chrysler material standard MS-6395, be used.
SAE Grade 10W-30 oils are also acceptable when the

these grades are not generally available, higher SAE
grades may be used.
Lubricants which have both an SAE grade number
and the proper API service classification shown on
the container should be used.

API quality or the CCMC G5 designation.
To assure of properly formulated engine oils, it is recom-
mended that SAE Grade 15W-40 engine oils that meet
Chrysler material standard MS-6395, be used. European
Grade 10W-40 oils are also acceptable.
Oils of the SAE 5W-30 or 10W-30 grade number
are preferred when minimum temperatures consis-

GENERAL INFORMATION
ACCESSORY DRIVE BELTS
The accessory drive system utilizes two different
style of drive belts. The conventional V-belt and the
Poly-V belt are used to drive the generator, air con-
ditioning compressor, power steering pump and waterpump. Satisfactory performance of these belts
depends on belt condition and proper belt tension.
Belt tensioning should be performed with the aid of a
Burroughs gauge Special Tool C-4162. Because of
space limitations in the engine compartment, the use
of the gauge may be restricted. Raise the vehicle on a
hoist and then remove the splash shield to gain
access to the drive belts.
NSCOOLING SYSTEM 7 - 1

COOLING SYSTEM
The cooling system has a radiator, coolant, electric fan
motor, shroud, pressure cap, thermostat, coolant reserve
system, transmission oil cooler, a water pump to circulate
the coolant, hoses, and clamps to complete the circuit.
²When Engine is cold: thermostat is closed, cool-
ing system has no flow through the radiator. The
coolant bypass flows through the engine only.
²
When Engine is warm: thermostat is open, cooling
system has bypass flow and coolant flow through radia-
tor.
Its primary purpose is to maintain engine temper-
ature in a range that will provide satisfactory engine
performance and emission levels under all expected
driving conditions. It also provides hot water (cool-
ant) for heater performance and cooling for automatic
transmission oil. It does this by transferring heat
from engine metal to coolant, moving this heated
coolant to the radiator, and then transferring this
heat to the ambient air.
Coolant flow circuits for 2.4L and 3.3/3.8L engines
are shown in (Fig. 1), and 3.0L engine coolant rout-
ing is shown in (Fig. 2)

GENERAL INFORMATION (Continued)

COOLANT RECOVERY SYSTEM (CRS)
This system works with the radiator pressure cap
to use thermal expansion and contraction of the cool-
ant to keep the coolant free of trapped air. Provides a
convenient and safe method for checking coolant
level and adjusting level at atmospheric pressure
without removing the radiator pressure cap. It also
provides some reserve coolant to cover deaeration
and evaporation or boiling losses. All vehicles are
equipped with this system and take various shapes
and forms. (Fig. 3) shows a typical system in the typ-
ical location.
See Coolant Level Service, and Deaeration, and
Pressure Cap sections for operation and service.
AUTOMATIC TRANSMISSION OIL COOLERÐ2.4L
Oil cooler is internal oil to coolant type, mounted
in the radiator left tank (Fig. 4). Rubber oil lines feed
the oil cooler and the automatic transmission. Use
only approved transmission oil cooler hose. Since
these are molded to fit space available, molded hoses
are recommended.
ENGINE THERMOSTAT
The engine cooling thermostats are a wax pellet
driven, reverse poppet choke type. They are designed
to provide the fastest warm up possible by prevent-
ing leakage through them and to guarantee a mini-
mum engine operating temperature of 88 to 93ÉC
(192 to 199ÉF). They also automatically reach wide
open so they do not restrict flow to the radiator as
temperature of the coolant rises in hot weather to
around 104ÉC (220ÉF). Above this temperature the
coolant temperature is controlled by the fan, the
radiator, and the ambient temperature, not the ther-
mostat.
WATER PUMPS
A quick test to tell whether the pump is working is
to see if the heater warms properly. A defective pump
can not circulate heated coolant through the long
heater hose.The water pump on all models can
be replaced without discharging the air condi-
tioning system.
COOLANT
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. Cool-
ant then carries this heat to the radiator, where the
tube/fin assemblies of these components can give it
up to the air.
The use of aluminum cylinder heads, intake mani-
folds, and water pumps requires special corrosion
protection. MopartAntifreeze or the equivalent is
recommended for best engine cooling without corro-
sion, when mixed only to a freeze point of -37ÉC
(-35ÉF) to -59ÉC (-50ÉF). If it loses color or becomes
contaminated, drain, flush, and replace with fresh
properly mixed solution.
CAUTION: Do not use well water, or suspect water
supply in cooling system. A 50/50 ethylene glycol
and distilled water mix is recommended.
RADIATOR
The radiators are cross-flow types (horizontal
tubes) with design features that provide greater
strength along with sufficient heat transfer capabili-

ties to keep the engine satisfactorily cooled (Fig. 5),
(Fig. 6), (Fig. 7) and (Fig. 8).
CAUTION: Plastic tanks, while stronger then brass
are subject to damage by impact, such as wrenches
etc., or by excessive torque on hose clamps.
If the plastic tank is damaged, replace the radia-
tor.
RADIATOR PRESSURE CAP
The radiator is equipped with a pressure cap that
releases excessive cooling system pressure; maintain-
ing a range of 97-124 kPa (14-18 psi).
The cooling system will operate at higher than
atmospheric pressure. The higher pressure raises thecoolant boiling point thus, allowing increased radia-
tor cooling capacity.
There is also a vent valve in the center of the cap.
This valve also opens when coolant is cooling and
contracting allowing coolant to return to radiator
from coolant reserve system tank by vacuum through
connecting hose.If valve is stuck shut, or the
coolant recovery hose is pinched, the radiator
hoses will be collapsed on cool down. Clean the
vent valve (Fig. 9) and inspect coolant recovery
hose routing, to ensure proper sealing when
boiling point is reached.
The gasket in the cap seals the filler neck, so that
vacuum can be maintained, allowing coolant to be
drawn back into the radiator from the reserve tank.

GENERAL INFORMATION (Continued)

If the gasket is dirty or damaged, a vacuum
may not be achieved, resulting is loss of coolant
and eventual overheating due to low coolant
level in radiator and engine.
ENGINE BLOCK HEATER
The engine block heater is available as an optional
accessory on all models. The heater is operated by
ordinary house current (110 Volt A.C.) through a
power cord located behind the radiator grille. This
provides easier engine starting and faster warm-up
when vehicle is operated in areas having extremely
low temperatures. The heater is mounted in a core
hole (in place of a core hole plug) in the engine block,
with the heating element immersed in coolant.
