FOREWORD
This manual is designed as a supplement to be used along with the 2002 Liberty service manual,
81-370-02060. It includes information related to the 2.4L gas engine installed in this vehicle by
DaimlerChrysler Corporation. For diagnosis or service procedures relating to other components or systems,
refer to the 2002 Liberty Service Manual.
The information contained in this service manual has been prepared for the professional automotive tech-
nician involved in daily repair operations. 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 description, operation, diagnosis,
testing, adjustments, removal, installation, disassembly, and assembly procedures for the systems and compo-
nents. 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. If you are not sure which Group contains the infor-
mation you need, look up the Component/System in the alphabetical index located in the rear of this manual.
A Service Manual Comment form is included at the rear of this manual. Use the form to provide
DaimlerChrysler Corporation with your comments and suggestions.
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
replacing fasteners, always use the same type (part number) fastener as removed.
DaimlerChrysler Corporation reserves the right to change testing procedures, specifications, diagnosis,
repair methods, or vehicle wiring at any time without prior notice or incurring obligation.
