1984 GMC Jimmy Service and Repair Manual

This factory service and repair manual for the 1984 GMC Jimmy is written around a single body style, the 2-door sport utility, offered in Base, High Sierra and Sierra Classic trim. Under the hood the year splits three ways, between the 5.0L and 5.7L gasoline V8s and the 6.2L diesel V8, each an overhead-valve, naturally aspirated design. The book follows every one of them through procedures, specifications, torque values, wiring diagrams and diagnostics, and gives the same treatment to the chassis, driveline and body systems that surround them.

Known issues on the 1984 Jimmy. Five owner complaints are logged with NHTSA for this model year. The largest group concerns the seats, with two entries, while the vehicle speed control and the power train draw one apiece. Seat anchorage and adjuster work, throttle linkage and speed control diagnosis, and transmission and driveline overhaul all sit in this manual with their own procedures, specifications and torque values, and the wiring diagrams trace the speed control circuit end to end for anyone chasing an intermittent fault in it.
