This factory service and repair manual for the 1987 GMC C5000 keeps to a narrow specification: one body style, the 2-door conventional cab and chassis; one trim code, C5D042; and two naturally aspirated gasoline engines, a 5.7L V8 of 350 cubic inches and a 4.8L overhead-valve inline-six of 292 cubic inches. Everything in the book is arranged around those, from engine specifications and torque values through to the wiring diagrams and diagnostic procedures for the chassis.

Known issues on the 1987 C5000. For the 1987 C5000 the federal record comes back clean — NHTSA lists no recalls and no owner complaints for the year. Trucks like this one usually reveal their weak points through age rather than through defect campaigns, which is where the manual earns its place: specifications and service procedures for the 292 inline-six and the 350 V8, torque values for the fasteners on both, and wiring diagrams and diagnostics for the conventional cab and chassis they were installed in.
