1987 GMC Jimmy Service and Repair Manual

This factory service and repair manual for the 1987 GMC Jimmy deals with a 2-door sport utility offered in just two trims, Base and Sierra Classic, but with three engines behind them: a 5.0L gasoline V8, a 6.2L diesel V8 and a 5.7L gasoline V8, all overhead-valve and naturally aspirated. Whichever is fitted, the procedures, specifications, torque values, wiring diagrams and diagnostics are indexed by system, so fuel, ignition and cooling work is found the same way for the diesel as for either gasoline V8.

Known issues on the 1987 Jimmy. One recall appears on the federal record, and it comes down to replacement lamps supplied without amber side reflectors, leaving the vehicle poorly illuminated to traffic approaching from the side. Owner complaints number seven, with the fuel system drawing two of them and tires and engine cooling one each. Fuel delivery is therefore worth the attention: the manual carries fuel pump and tank service, pressure specifications and the diagnostic sequence for the system, alongside cooling system procedures and the torque values for the components involved.
