2004 GMC Envoy XL Service and Repair Manual
This factory service and repair manual for the 2004 GMC Envoy XL documents the four-door sport utility in SLE and SLT trim, powered by a 256-cubic-inch inline-six or a 325-cubic-inch V8, the first with twin overhead camshafts and the second with pushrods. Those two engines carry different clearances, different torque sequences and different fuel and emissions hardware, and the manual keeps their procedures distinct. Everything downstream of the engine, from driveline and suspension to steering, brakes, climate, restraints and the body circuits, is covered once, with specifications, wiring diagrams and diagnostic routines.
