1982 GMC Caballero Service and Repair Manual
This factory service and repair manual for the 1982 GMC Caballero covers a two-door standard cab pickup offered in three trims, Base, Amarillo and Diablo, with three naturally aspirated OHV gasoline engines behind them. The largest is the 5.0L V8, the smallest is the 3.8L V6, and between them sits the 4.4L V8, an unusual displacement that makes engine-specific figures worth having on hand. Specifications, torque values, wiring diagrams and diagnostics are given for each of the three.

Known issues on the 1982 Caballero. The federal record for this year is clean, showing no recalls and no owner complaints logged with NHTSA. That is worth knowing on a vehicle old enough that most of what goes wrong now is wear rather than design, and wear is exactly what a factory manual addresses. Procedures, specifications, torque values, wiring diagrams and diagnostics are provided for the 3.8L V6 and the 4.4L and 5.0L V8s, and for the pickup body in all three trims.
