2002 Chevrolet Sonora Service and Repair Manual
This factory service and repair manual for the 2002 Chevrolet Sonora deals with two trims, LS and LT, one four-door sport utility body, and one engine, the naturally aspirated 5.7L OHV V8 of 350 cubic inches on gasoline. For a shop, that combination keeps the diagnostic path short: a symptom leads to one engine's specifications and one set of chassis torque values rather than through a decision tree of engine and package options before any work can begin.

Known issues on the 2002 Sonora. No recalls and no owner complaints appear on the federal record for this year, which leaves the manual to be read as a service reference rather than as a repair history. It sets out engine mechanical work for the 350-cubic-inch V8 with its clearances and torque values, fuel and emissions diagnosis, cooling and lubrication specifications, brake hydraulics and friction service, steering and suspension procedures, and the wiring diagrams and step-by-step diagnostics for the vehicle's electrical circuits.
