1998 Chevrolet C2500 Service and Repair Manual
This factory service and repair manual for the 1998 Chevrolet C2500 picks up a fourth body, a three-door extended cab alongside the two-door extended cab, the standard cab and the bare chassis cab, which matters more than it sounds because a third door changes latch, hinge, wiring and trim procedures. Engines number four: the 5.0L and 7.4L gasoline V8s, the turbocharged 6.5L diesel, and the 5.7L V8 arranged for compressed natural gas or gasoline. Six trims, from Base and WT up to Silverado, are covered.

Known issues on the 1998 C2500. The federal record for this model year is clean, carrying neither recalls nor owner complaints. The manual's job is the day-to-day one: establishing which of the four engines is in the truck and giving its clearances, torque values and diagnostic routines; separating the natural-gas fuel system from the gasoline and diesel ones; covering transmission, transfer case and axle overhaul; brake and steering specifications; and the body and wiring differences between four cab configurations across six trims.
