2008 GMC Yukon XL 1500 Service and Repair Manual
This factory service and repair manual for the 2008 GMC Yukon XL 1500 spans a three-engine lineup in one 4-door sport utility body. The 6.0L V8 of 364 cubic inches and the 6.2L V8 of 376 cubic inches both run on gasoline; the 5.3L V8 of 325 cubic inches was built to take flex-fuel or gasoline. All three are overhead-valve and naturally aspirated, and all three appear across the Denali, SLE and SLT trims. Fuel, ignition and engine mechanical work is therefore documented three ways, with the chassis and body procedures shared between them.

Known issues on the 2008 Yukon XL 1500. The federal record lists four recalls, and they fall into two groups. On the restraint side, frontal passenger airbag inflators can rupture during deployment and send metal fragments through the cabin, a defect tied to long exposure to heat and humidity. On the electrical side, the heated washer fluid module can short at its printed circuit board, causing odor, smoke and in some cases a fire. That matches what owners report: of 411 complaints, 189 name airbags, 55 the electrical system and 32 the structure. Restraint diagnostics and body wiring diagrams are the sections to reach for.
