This factory service and repair manual for the 1986 GMC P3500 opens on a four-engine lineup, the 7.4L V8 and 5.7L V8 on gasoline, the 4.8L inline-six also on gasoline and the 6.2L V8 diesel, and follows each through the same structure of procedures and specifications. Body-wise there are two entries, the two-door delivery van and the chassis, offered as Base Stripped or Value. Torque values, wiring diagrams and diagnostic charts sit alongside the repair steps for every system, so a job on the frame and a job under the engine cover are looked up the same way.
