This factory service and repair manual for the 2005 Chevrolet Sonora documents a four-door sport utility in Base specification, powered by the naturally aspirated 5.3L OHV V8 of 325 cubic inches on gasoline. Everything in the book resolves to that one combination: the fuel and ignition figures, the cooling and lubrication specifications, the transmission and driveline procedures, the brake and steering torque values, and the wiring diagrams for the charging, starting, lighting and accessory circuits. A technician never has to ask which variant a figure belongs to.
