2014 Chevrolet Express 3500 Service and Repair Manual

This factory service and repair manual for the 2014 Chevrolet Express 3500 lists three trims, Base, LS and LT, across seven bodies, but the divide that actually matters mechanically is the engine: 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 configured for compressed natural gas or flex-fuel. Each brings its own fuel handling, its own emissions hardware and its own diagnostic routines, and the manual keeps them apart rather than blending them together.

Known issues on the 2014 Express 3500. This model year carries neither a recall nor a single owner complaint federally. What the manual covers, then, is ordinary work done properly: cylinder head, timing and lubrication procedures with the clearances and torque sequences for each engine; fuel storage and metering, including the natural gas arrangement; automatic transmission and rear axle overhaul; brake, steering and suspension specifications for a chassis meant to carry load; and body, glass and interior repair backed by full wiring diagrams.
