1989 GMC Jimmy Service and Repair Manual

This factory service and repair manual for the 1989 GMC Jimmy keeps to one body, the 2-door sport utility, and two trims, Base and Sierra Classic. Buyers chose between the 6.2L diesel V8 and the 5.7L gasoline V8, each overhead-valve and naturally aspirated, and both are documented here to the same depth. Engine mechanical work, fuel and cooling, transmission and axle service, steering, brakes and the electrical system all appear with their own procedures, specifications, torque values, wiring diagrams and diagnostic charts.

Known issues on the 1989 Jimmy. One recall stands against this model year, concerning replacement lamps without amber side reflectors and the poor illumination that results from leaving them off. Thirteen owner complaints are recorded with NHTSA, the heaviest concentrations being three on the service brakes, three on seat belts and two on the electrical system. Brake hydraulic and friction overhaul, belt anchorage torque figures and the full set of wiring diagrams with their diagnostic charts are where this manual answers that pattern, circuit by circuit and component by component.
