DODGE RAM 1500 SERIES 2002-2004 SERVICE REPAIR WORKSHOP MANUAL
VEHICLE/EQUIPMENT INTRODUCTION:
The 2002 to 2004 Dodge Ram 1500 represents the second generation of the bold styling that Dodge introduced with the 1994 model year redesign. This generation of Ram 1500 continued the crosshair grille and muscular fender aesthetic that separated it from the competition, while receiving incremental improvements in refinement, interior quality, and drivetrain options.
Powertrain choices included the reliable Magnum inline-six 3.9-liter V6, the workhorse 5.2-liter 318 cubic inch V8, and for those needing maximum towing, the available 5.9-liter 360 V8. Chrysler also offered the legendary Cummins 5.9-liter 24-valve turbo diesel in the heavier duty variants. The 1500 series was available in regular cab, club cab, and quad cab configurations with both two-wheel and four-wheel drive.
The second-generation Ram 1500 built a strong reputation for capable towing, rugged chassis components, and straightforward V8 power that appealed to truck buyers who valued function over form. Today these trucks remain popular work vehicles and restoration projects thanks to abundant parts availability and this comprehensive service manual ensuring proper maintenance procedures.
