This factory service and repair manual for the 1984 GMC C5000 covers a single conventional 2-door cab and chassis, cataloged under one trim code, C5D042, and offered with two naturally aspirated gasoline engines. One is the 5.7L V8 at 350 cubic inches; the other is the 4.8L overhead-valve inline-six at 292 cubic inches. Because the truck left the factory as a chassis waiting for a body, the manual concentrates on the running gear, working through it system by system with procedures, specifications, torque values, wiring diagrams and diagnostics.

Known issues on the 1984 C5000. The 1984 C5000 has a clean federal record: NHTSA shows no recalls and no owner complaints for the year. That leaves the manual to do ordinary work, which on this truck means the two gasoline engines — the 292 inline-six and the 350 V8 — and the chassis they sit in. Procedures, specifications, torque values, wiring diagrams and diagnostics are given for those systems, which is what matters most on a vehicle likely to be kept running well past its original service life.
