2013 Chevrolet Suburban 2500 Service and Repair Manual

This factory service and repair manual for the 2013 Chevrolet Suburban 2500 works from one engine specification: a naturally aspirated 6.0L overhead-valve V8 of 364 cubic inches, built to run on flex fuel or gasoline. That engine sits in a four-door sport utility offered in LS and LT trim. Dual fuel capability puts extra weight on the control side of the engine chapters, and the fuel, ignition and emissions diagnostics are written accordingly, ahead of the transmission, axle, brake, steering and body electrical procedures.

Known issues on the 2013 Suburban 2500. This model year drew 118 owner complaints. The air bags account for 27, the structure for 15 and the electrical system for 13, with the remainder thinly spread. A technician chasing any of those will use the restraint component tests and connector checks, the body and frame procedures with their specified torque values, and the circuit diagrams that show where each electrical branch runs and what shares its supply and ground, all of which this manual sets out system by system.
