GENERAL How to Use This
HOW TO USE THIS MANUAL
MAINTENANCE, REPAIR AND
SERVICING EXPLANATIONS
This manual provides explanations, etc. concerning procedures for the inspection, maintenance, repair
and servicing of the subject model. Unless other-
wise specified, each service procedure covers all
models. Procedures covering specific models are
identified by the model codes, or similar designati on
(engine type, transaxle type, etc.). A description
of these designations is covered in this manual
under “VEHICLE IDENTIFICATION”.
ON-VEHICLE SERVICE
“On-vehicle Service” are procedures for performing
inspections and adjustments of particularly impor-
tant locations with regard to the construction and
for maintenance and servicing, but other inspec-
tions (for looseness, play, cracking, damage, etc.
must also be performed.
SERVICE PROCEDURES
The service steps are arranged in numerical order
and attention must to be paid in performing vehicle
service are described in detail in SERVICE POINTS.
TERMS DEFINITION
STANDARD VALUE
Indicates the value used as the standard for judgin g
the quality of a part or assembly on inspection
or the value to which the part or assembly is cor-
rected and adjusted. It is given by tolerance.
LIMIT
Indicates a maximum or minimum value, the part
or assembly should be kept within, in order to be functional. This value is established outside the
standard value range.
REFERENCE VALUE
Indicates the adjustment value prior to starting th e
work (presented in order to facilitate assembly and
adjustment procedures, and so they can be com-
pleted in a shorter time).
CAUTION
Indicates the presentation of information particula rly
vital to the worker during the performance of maint e-
nance and servicing procedures in order to avoid
the possibility of injury to the worker, or damage
to component parts, or a reduction of component
or vehicle function or performance, etc..
TIGHTENING TORQUE INDICATION
The tightening torque shown in this manual is a
basic value with a tolerance of
10% except the
following cases when the upper. and
of tightening torque are given. (1) The tolerance of the ‘basic value
10%.
(2) Special bolts or, the ‘like are
(3) Special tightening methods are used.
SPECIAL TOOL NOTE
When the MMC special tool is described, please
refer to the special tool
is located at the beginning of each group, for a
cross reference from the tool, number
to the special tool number that available in your
market..

The following abbreviations are used in this manual for classification of model types.
M/T
Indicates the manual transaxle, or models equipped with the manual transaxle.
A/T
Indicates the automatic transaxle, or models equip ped with the automatic transaxle.

FORM-IN-PLACE GASKETS
There are numerous places where form-in-place gaskets are used on the engine. Care must be
when applying form-in-place gaskets to assure obtaining the desired results. size, continuity, ‘and
location are of great importance. Too thin a bead can result in leakage
too much can result’ in
spill-over which can break off and obstruct fluid f eed lines.
A continuous bead of the proper width
essential to obtain a leak-free joint.
GASKET DISASSEMBLY
Parts assembled with form-in-place gaskets may be d isassembled without unusual effort’
it may be necessary to lightly tap the part with a mallet or other suitable tool to break the seal between
the mating surfaces.A flat gasket scraper may also be lightly tapped in to the joint but care be
taken not to damage the mating surfaces.
SURFACE PREPARATION
Scrape clean or wire brush all gasketsurfaces removing all loose material. Inspect
assure gasket rails are flat.
Flatten rails with a hammer on a flat plate if
must be free of oil and dirt. Make sure old gasket material is removed from blind
FORM-IN-PLACE GASKET APPLICATION
Assembling parts using a form-in-place gasket requires care but it’s easier than using precut gaskets.
Gasket material should be applied sparingly 1 mm
inch.) diameter or less to one
surface, Be certain the material surrounds each mou nting hole.
Excess material can easily be
‘off. Components should be torqued in place within 15 minutes. The use of a locating dowel is recommen ded
during assembly, to prevent smearing the material off location.
Loctite 18718 gasket material or equivalent should be applied in a continuous bead
3
mm
inch.) in diameter. All mounting holes must be circled.
For corner sealing, 3.17 or 6.35
mm
or inch.) drop is placed in the center of the gasket contact area. Uncured may
be removed with a shop towels. Components should be torqued in place while the sea lant

to the touch (within 10 minutes). The usage of a locating dowel is recommended during assembly to
prevent smearing of material off location.
MOPAR TORQUE CURE GASKET MAKER
Mopar torque cure gasket maker is a unique anaerobi c type gasket material to be used ONLY
the and engine block. The material cures in the absenc e of air when. two
metallic surfaces. It will not cure if left in the uncovered tube. This anaerobic material
specially made
to seal the area between the
and cylinder block without disturbing the bearing’ or
alignment of these components.. .
