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.
Engines covered
- 4.3L V6 (262 cu in) — OHV, naturally aspirated, gasoline

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.
CERTAIN PICKUP TRUCKS AND SPORT UTILITY VEHICLES FAIL TO COMPLY WITH THE REQUIREMENTS OF FEDERAL MOTOR VEHICLE SAFETY STANDARD NO. 208, "OCCUPANT CRASH PROTECTION."
SOME OF THESE VEHICLES INCLUDE INCORRECT STATEMENTS ON ONE OF THE AIR BAG WARNING LABELS.
OWNERS WILL BE PROVIDED WITH CORRECT LABELS AND INSTALLATION INSTRUCTIONS. OWNER NOTIFICATION BEGAN
