1987 GMC Caballero Service and Repair Manual
This factory service and repair manual for the 1987 GMC Caballero takes on a two-door standard cab pickup offered in Base and Diablo trim, with a choice of two naturally aspirated OHV gasoline engines: a 5.0L V8 or a 4.3L V6. Two trims and two engines make for a compact scope, and the manual uses it well, giving the V8 and the V6 their own specifications, torque values, wiring diagrams and diagnostic procedures rather than one shared summary.
