1998 Chevrolet C3500 Service and Repair Manual

This factory service and repair manual for the 1998 Chevrolet C3500 is written for a truck badged only Cheyenne or Silverado but narrow in no other respect. The turbocharged 6.5-liter diesel of 395 cubic inches, the dual-fuel 5.7-liter 350 running compressed natural gas or gasoline, and the naturally aspirated 7.4-liter 454 all appear, mounted in any of five bodies: standard, extended and crew cab pickups, and two- and four-door cab and chassis. Each combination brings its own specifications and wiring, and the manual separates them where it matters.
