This factory service and repair manual for the 1989 Chevrolet C50 has one engine, one body and one order code to describe: a medium-duty conventional cab and chassis, code C5D042, powered by the naturally aspirated 5.7-liter gasoline V8 of 350 cubic inches. That simplicity is worth something in a shop, because there is no engine option to identify before turning to a specification table, and the wiring diagrams describe one harness rather than several variants. Everything from engine clearances to brake adjustment figures refers to the same truck.
