2004 GMC Sonoma Service and Repair Manual

This factory service and repair manual for the 2004 GMC Sonoma has a short specification to cover: a single engine, the naturally aspirated overhead-valve 4.3L V6 of 262 cubic inches; a single body, the four-door crew cab pickup; and two trims, SL and SLS. That leaves room for depth instead of breadth, with engine mechanical, fuel, ignition, transmission, axle, brake, steering, suspension, body and wiring work each carrying its own procedures, specifications, torque values, wiring diagrams and diagnostics.

Known issues on the 2004 Sonoma. One recall is on the federal record here, and it concerns air bag warning labels printed with incorrect statements, which left the trucks short of the federal occupant crash protection standard. Just one owner complaint is logged, and it relates to the structure. With so little history to work from, the value of this manual sits in its ordinary content: the specifications, torque values, wiring diagrams and step-by-step diagnostics for the 4.3L V6 crew cab and every system around it.
