2005 GMC Envoy XUV Service and Repair Manual

This factory service and repair manual for the 2005 GMC Envoy XUV serves a four-door sport utility offered in two trims, SLE and SLT, and with two engines that demand separate treatment, the 256-cubic-inch 4.2L DOHC inline-six and the 325-cubic-inch 5.3L OHV V8. Clearances, valve train service, cooling capacities and emissions hardware differ between them, so those chapters are split. The chassis, brake, driveline, climate and circuit chapters are shared, each carrying its own diagrams, torque values and diagnostics.
