This factory service and repair manual for the 2006 Chevrolet Sonora describes a four-door sport utility whose only engine is the naturally aspirated 5.3L OHV V8 of 325 cubic inches and whose only equipment level is Base. That makes it a straightforward reference to use: diagnosis starts from the symptom rather than from a question about which engine or package the vehicle carries, and the specifications, torque values and wiring diagrams that follow apply without qualification. Engine, driveline, chassis and body electrical work are each covered in their own right.
