2012 GMC Sierra Service and Repair Manual
Regular price
$29.99 USD
Unit price
This factory service and repair manual for the 2012 GMC Sierra carries the same pair of naturally aspirated, overhead-valve flex-fuel V8s that define the truck in this period, the 325-cubic-inch 5.3L and the 376-cubic-inch 6.2L. Two cabs are listed, the two-door standard cab pickup and the four-door crew cab, and two trims, Base and Denali. Everything is arranged by system rather than by trim, so trim level rarely changes a lookup, and the diagnostics stay in one place.

- 6.2L V8 (376 cu in) — OHV, naturally aspirated, flex-fuel

Known issues on the 2012 Sierra. Three recalls appear on the federal record for this year. Two of them address a front passenger air bag inflator that can rupture as it deploys and send sharp metal into the passenger compartment. The third concerns fire extinguishers shipped with the truck that may become clogged and fail to work when a fire starts. Complaint volume is low by the standards of this model line at 49 entries, spread thinly across the electrical system with 9, the structure with 7 and the steering with 7. Restraint and harness diagnostics remain the useful sections.
