1984 GMC Caballero Service and Repair Manual
This factory service and repair manual for the 1984 GMC Caballero documents three engines in a single body style. The body style is the two-door standard cab pickup; the trims are Base, Amarillo and Diablo. Two of the engines are naturally aspirated OHV gasoline units, a 5.0L V8 and a 3.8L V6, and the third is a naturally aspirated 5.7L OHV diesel V8. Because a diesel and two gasoline engines share one platform here, the manual keeps their sections and their figures apart.
