GENERAL INFORMATION
VEHICLE IDENTIFICATION NUMBER
The Vehicle Identification Number (VIN) plate is
located on the lower windshield fence near the left
A-pillar. The VIN contains 17 characters that provide
data concerning the vehicle. Refer to the VIN decod-
ing chart to determine the identification of a vehicle.
The Vehicle Identification Number is also
imprinted on the:
•Body Code Plate.
•Vehicle Safety Certification Label.
•Frame rail.
To protect the consumer from theft and possible
fraud the manufacturer is required to include a
Check Digit at the ninth position of the Vehicle Iden-
tification Number. The check digit is used by the
manufacturer and government agencies to verify the
authenticity of the vehicle and official documenta-
tion. The formula to use the check digit is not
released to the general public.

VEHICLE SAFETY CERTIFICATION LABEL
A vehicle safety certification label (Fig. 1) is
attached to every Chrysler Corporation vehicle. The
label certifies that the vehicle conforms to all appli-
cable Federal Motor Vehicle Safety Standards. The
label also lists:
•Month and year of vehicle manufacture.
•Gross Vehicle Weight Rating (GVWR). The gross
front and rear axle weight ratings (GAWR’s) are
based on a minimum rim size and maximum cold tire
inflation pressure.
•Vehicle Identification Number (VIN).
•Type of vehicle.
•Bar code.
•Month, Day and Hour (MDH) of final assembly.
•Paint and Trim codes.
•Country of origin.
The label is located above the door hinge on the
driver-side A-pillar.
BODY CODE PLATE
LOCATION AND DECODING
A metal body code plate is attached to the floor pan
under the drivers seat (Fig. 2). Disengage the snaps
attaching the carpet to the floor pan to read the
information. There are seven lines of information on
the body code plate. Lines 4, 5, 6, and 7 are not used
to define service information. Information reads from
left to right, starting with line 3 in the center of the
plate to line 1 at the bottom of the plate (Fig. 3).
The last code imprinted on a vehicle code plate will
be followed by the imprinted word END. When two
vehicle code plates are required, the last available
spaces on the first plate will be imprinted with the
letters CTD (for continued).
When a second vehicle code plate is necessary, the
first four spaces on each row will not be used because
of the plate overlap.

FASTENER IDENTIFICATION
FASTENER IDENTIFICATION
THREAD IDENTIFICATION
SAE and metric bolt/nut threads are not the same.
The difference is described in the Thread Notation
chart (Fig. 5).
GRADE/CLASS IDENTIFICATION
The SAE bolt strength grades range from grade 2
to grade 8. The higher the grade number, the greater
the bolt strength. Identification is determined by the
line marks on the top of each bolt head. The actual
bolt strength grade corresponds to the number of line
marks plus 2. The most commonly used metric bolt
strength classes are 9.8 and 12.9. The metric
strength class identification number is imprinted on
the head of the bolt. The higher the class number,
the greater the bolt strength. Some metric nuts are
imprinted with a single-digit strength class on the
nut face. Refer to the Fastener Identification and
Fastener Strength Charts.
FASTENER USAGE
WARNING: USE OF AN INCORRECT FASTENER
MAY RESULT IN COMPONENT DAMAGE OR PER-
SONAL INJURY.
Figure art, specifications and torque references in
this Service Manual are identified in metric and SAE
format.
During any maintenance or repair procedures, it is
important to salvage all fasteners (nuts, bolts, etc.)
for reassembly. If the fastener is not salvageable, a
fastener of equivalent specification must be used.

THREADED HOLE REPAIR
Most stripped threaded holes can be repaired using
a Helicoilt. Follow the manufactures recommenda-
tions for application and repair procedures.
METRIC SYSTEM
The metric system is based on quantities of one,
ten, one hundred, one thousand and one million (Fig.
6).
The following chart will assist in converting metric
units to equivalent English and SAE units, or vice
versa.
Refer to the Conversion Chart to convert torque
values listed in metric Newton- meters (N·m). Also,
use the chart to convert between millimeters (mm)
and inches (in.)
