GENERAL INFORMATION
INTRODUCTION
Service and maintenance procedures for compo-
nents and systems listed in Schedule ± A or B can be
found by using the Group Tab Locator index at the
front of this manual. If it is not clear which group
contains the information needed, refer to the index at
the back of this manual.
There are two maintenance schedules that show
proper service based on the conditions that the vehi-
cle is subjected to.
Schedule ±A, lists scheduled maintenance to be
performed when the vehicle is used for general trans-
portation.
Schedule ±B, lists maintenance intervals for vehi-
cles that are operated under the conditions listed at
the beginning of the Maintenance Schedule section.
Use the schedule that best describes your driving
conditions.
Where time and mileage are listed, follow the
interval that occurs first.

NOTE: Operating vehicle more than 50% in heavy
traffic during hot weather, above 90ÉF (32ÉC), using
vehicle for police, taxi, limousine type operation or
trailer towing require the more frequent transaxle
service noted in Schedule ± B. Perform these ser-
vices if vehicle is usually operated under these con-
ditions.
Inspection and service should also be performed
anytime a malfunction is observed or suspected.

GENERAL INFORMATION
ENGINE OIL Ð GASOLINE ENGINES
Use only oils conforming to API (American Petro-
leum Institute) Quality SJ and Energy Conserving II,
or SH and Energy Conserving II, or ACEA A1±96.
SAE VISCOSITY GRADE
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
temperatures do not fall below 0ÉC. In areas where
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.
ENGINE OILÐDIESEL ENGINES
Use only Diesel Engine Oil meeting standardMIL-
2104Cor API ClassificationSG/CDorCCMC PD2.
SAE VISCOSITY GRADE
CAUTION: Low viscosity oils must have the proper
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-
tently fall below -12ÉC.
MANUAL TRANSMISSION FLUID (A-558 and A-598
Models)
Use only SAE 10W-40 engine oils carrying the
European CCMC-G5 classification to fill the A-598
5±speed manual transmission.

ings in kilometers. There are two maintenance sched-
ules that show proper service intervals. Use the
schedule that best describes the conditions the vehi-
cle is operated under.Schedule-Alists all the sched-
uled maintenance to be performed under normal
operating conditions.Schedule-Bis the schedule for

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)
