1991 GMC G2500 Service and Repair Manual
This factory service and repair manual for the 1991 GMC G2500 has to answer for four engines and three bodies at once. The engines are the naturally aspirated 4.3L V6, 5.0L V8, 5.7L V8 and 6.2L diesel V8, every one overhead-valve; the bodies are the 3-door standard cargo van and the extended cargo and passenger vans. Trim badges read Rally, Rally STX or Vandura. Because coverage is arranged by system, the procedures, specifications, torque values, wiring diagrams and diagnostics for any one of those combinations sit together instead of scattered across the book.

Known issues on the 1991 G2500. There are no recalls on the federal record for the 1991 G2500 and no owner complaints logged with NHTSA, so the year is clean. That puts the emphasis back on service data: fuel, ignition and cooling specifications for the three gasoline engines, service procedures for the 6.2L diesel V8, brake and steering torque values, wiring diagrams for the van's lighting and accessory circuits, and diagnostics for each of those systems, which is what a van still in daily use tends to need.
