2012 Chevrolet Cheyenne Service and Repair Manual

This factory service and repair manual for the 2012 Chevrolet Cheyenne is built on one V8 and six combinations of cab and trim. The engine is the 325-cubic-inch 5.3L, overhead valve and naturally aspirated, calibrated to run flex-fuel or gasoline; the cabs are a four-door extended, a two-door standard and a four-door crew; the trims are LT and LTZ. Powertrain content is single-track. Body, interior and electrical content branches, because cab length and equipment level both change what the harnesses have to reach.

Known issues on the 2012 Cheyenne. The manual specifies the V8 for torque, clearance and timing, documents the fuel and emissions systems that a flex-fuel calibration relies on, and provides the diagnostic sequences for each. Transmission, driveline and axle procedures follow, the brake, steering and suspension sections carry their service figures, and the body chapters cover three cab structures plus the trim-level differences in the electrical system.
