2012 Chevrolet Silverado 2500 Service and Repair Manual
This factory service and repair manual for the 2012 Chevrolet Silverado 2500 is written around a truck sold only as a Base model, so the variation a technician tracks is mechanical rather than trim-driven: standard, extended or crew cab, and either the 4.8L V8 of 294 cubic inches or the 5.3L of 325, both overhead-valve, naturally aspirated and set up for flex-fuel. Fuel, ignition, emissions and driveline sections all carry the specifications for whichever of those two engines is in front of you.

Known issues on the 2012 Silverado 2500. Three recalls stand on the record for 2012. Two are air bag inflators that can burst rather than inflate once their propellant has degraded, spraying metal into the cabin; the third is a fire extinguisher that may clog and refuse to discharge when it is needed. Complaints number 121: 23 on the air bags, 14 on the power train and 13 on the structure. Restraint diagnostics, transmission and driveline procedures, and body and frame specifications are the parts of this manual those numbers point at.
