1985 GMC Jimmy Service and Repair Manual

This factory service and repair manual for the 1985 GMC Jimmy documents a truck sold in three trims, Base, High Sierra and Sierra Classic, in one 2-door sport utility body. Three engines are covered: the 5.0L gasoline V8, the 6.2L diesel V8 and the 5.7L gasoline V8, all overhead-valve and naturally aspirated. Torque values, specifications, wiring diagrams, diagnostics and step-by-step procedures are laid out system by system, so a rebuild on the diesel and a tune-up on the 5.0L each have their own numbers rather than a shared approximation.

Known issues on the 1985 Jimmy. One recall stands on the federal record here, and it concerns replacement lamps supplied without amber side reflectors, leaving the vehicle poorly illuminated and raising the risk of a crash. Six owner complaints are logged with NHTSA, spread thinly across visibility, seat belts and the service brakes with one entry each. Those are all systems the manual works through in detail: lighting and wiper circuits in the wiring diagrams, belt anchorage torque figures in the body section, and brake hydraulic and friction service with the specifications that go with it.
