2012 Chevrolet Suburban 1500 Service and Repair Manual

This factory service and repair manual for the 2012 Chevrolet Suburban 1500 has two engines in its tables: the 5.3L overhead-valve V8 of 325 cubic inches running flex fuel, and the 6.0L of 364 running gasoline, both naturally aspirated. One four-door sport utility body carries them in Base, LS, LT and LTZ form. Coverage is organized so engine work can be followed without wandering into the other displacement's figures, and so chassis and body procedures can be reached without going through the engine sections at all.

Known issues on the 2012 Suburban 1500. Owners have logged 101 complaints against this model year, with air bags at 23, structure at 19 and the electrical system at 10 forming the top of the list. Those three describe the restraint, body and wiring side of the truck rather than its mechanicals, and the manual gives each of them room: air bag system handling and disable procedures, sensor and module testing, body panel and closure repair with fastener specifications, and circuit diagrams with ground locations and diagnostic sequences for an electrical fault.
