2013 Chevrolet Express 2500 Service and Repair Manual

This factory service and repair manual for the 2013 Chevrolet Express 2500 covers a turbocharged 6.6L diesel V8 of 403 cubic inches, a flex-fuel 4.8L V8 of 294 and a 6.0L V8 of 364 built for compressed natural gas or E85, in five body configurations across Base, LS and LT trim.

Known issues on the 2013 Express 2500. Twenty-two complaints are recorded for this year, service brakes and the electrical system level at five each and air bags at two. On a van this size those two systems meet in more places than owners realize, since anti-lock sensors, the stop lamp switch, the warning lamps and the trailer circuits share wiring. The manual supplies hydraulic brake overhaul and friction limits, the anti-lock diagnostic sequence, complete circuit diagrams, and the restraint checks behind an air bag warning that will not clear.
