FOREWORD The information contained in this service manual has been prepared for the professional automotive tech- nician involved in daily repair operations. This manual does not cover theory of operation, which is addressed in service training material. Information describing the operation and use of standard and optional equipment is included in the Owner's Manual provided with the vehicle. Information in this manual is divided into groups. These groups contain general information, diagnosis, testing, adjustments, removal, installation, disassembly, and assembly procedures for the components. The Component and System Index of this manual identifies the correct group for the component or system to be serviced. In addition, a Service Manual Comment form is included at the rear of this manual. Use the form to provide Chrysler Corporation with your comments and suggestions. To assist in locating a group title page, use the Group Tab Locator on the following page. The solid bar after the group title is aligned to a solid tab on the first page of each group. The first page of the group has a contents section that lists major topics within the group. Tightening torques are provided as a specific value throughout this manual. This value represents the midpoint of the acceptable engineering torque range for a given fastener application. These torque values are intended for use in service assembly and installation procedures using the correct OEM fasteners. When re- placing fasteners, always use the same type (part number) fastener as removed. Chrysler Corporation reserves the right to change testing procedures, specifications, diagnosis, repair methods, or vehicle wiring at any time without prior notice or incurring obligation. NOTE: The acronyms, terminology and nomenclature used to identify emissions related components in this manual may have changed from prior publications. These new terms are in compliance with S.A.E. recommended practice J1930. This terminology standard (J1930) is required to comply with the 1993 California Air Research Board (CARB) requirements.

The codes are used to identify vehicle types in charts, captions and in service procedures. The vehicle codes are dif- ferent than the Vehicle Identification Number (VIN) or the wheelbase/model code. VEHICLE SAFETY CERTIFICATION LABEL A certification label is attached to the left side B-pillar. The label certifies that the vehicle conforms to Federal Motor Vehicle Safety Standards (FMVSS). The label also lists the: • 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 Type of rear wheels (single or dual) Bar code Month, Day and Hour (MDH) of final assembly VEHICLE IDENTIFICATION NUMBER (VIN) PLATE The Vehicle Identification Number (VIN) plate is attached to the top left side of the instrument panel. The VIN contains 17 characters that provide data concerning the vehicle.

VEHICLE CODE PLATE A metal vehicle code plate (Fig. 2) is attached to top, right side of cowl below cowl grille. There can be a maximum of seven rows of vehicle information im- printed on the plate. The information should be read from left to right, starting with line 1 at the bottom of the plate up to line 7 (as applicable) at the top of the code plate. Refer to the decoding chart to decode lines 1 through 3. Lines 4 through 7 on the plate are imprinted in se- quence according to the following descriptions: • 3-character sales code • 3-digit numerical code • 6-digit SEC code If there is not enough space left in the row for all of the 6-digit SEC code: • The unused space will remain blank • The code will be listed in the next row. The last nine positions of row 7 will contain a 2-digit code and a 6-digit serial number. The last code on a vehicle code plate will be fol- lowed by the imprinted word END. When two plates are required, the last available spaces on the first plate will be imprinted with the letters CTD (for con- tinued). When a second vehicle code plate is necessary, the first four spaces on each row will not be used because of the plate overlap. To retrieve information from a vehicle code plate: • Illuminate the plate with a shop light • View the plate via the cowl grille slots • Record the needed coded information. ENGINE AND TRANSMISSION/TRANSFER CASE IDENTIFICATION Refer to Group 9—Engines for all engine identifi- cation data.
