1999 GMC Jimmy Service and Repair Manual

This factory service and repair manual for the 1999 GMC Jimmy takes in the Envoy, SL, SLE, SLS and SLT trims and both sport utility bodies, 4-door and 2-door. One engine serves the lot: the 4.3L overhead-valve V6, naturally aspirated and gasoline-fueled. That single powerplant anchors the mechanical sections, and from it the book branches out into transmission and axle overhaul, steering and suspension, brake hydraulics, heating and air conditioning, the electrical system and the body, each with procedures, specifications, torque values and diagnostics of its own.

Known issues on the 1999 Jimmy. Owner complaints for this model year run to 163, and they spread fairly evenly across the chassis: 22 concern the suspension, 21 the power train and 19 the service brakes. Those three sit at the center of the manual's mechanical coverage. Front suspension overhaul with its ball joint and control arm torque values, transmission and axle service, and brake hydraulic and friction procedures are each set out step by step, backed by the diagnostic charts and wiring diagrams needed to confirm a fault before parts come off the truck.
