This factory service and repair manual for the 1987 GMC P3500 documents a delivery van and a chassis that share everything under the sheetmetal, including a choice of four overhead-valve engines: the 7.4L V8, the 5.7L V8 and the 4.8L inline-six on gasoline, and the 6.2L V8 diesel. None is turbocharged. Both bodies were sold in Base Stripped and Value form. The manual is written to be searched by system, with procedures, specifications, torque values, wiring diagrams and diagnostics kept together for each area of the truck.

Known issues on the 1987 P3500. Nothing has been recalled on the 1987 P3500 and no owner complaint has been filed with NHTSA, leaving the federal record clean for this model year.
