2024 GMC Yukon XL Service and Repair Manual

This factory service and repair manual for the 2024 GMC Yukon XL covers a four-door sport utility built in five trims and offered with three engines: a 5.3L overhead-valve gasoline V8, a 6.2L overhead-valve gasoline V8 and a turbocharged 3.0L double overhead cam inline-six diesel. From AT4 to Denali Ultimate the mechanical package draws on the same set of parts, so the engine sections do the sorting while the chassis, brake, body and electrical sections apply throughout, with their own specifications, torque values and wiring diagrams.

Known issues on the 2024 Yukon XL. Two recalls are on the record for this model year. One covers 6.2L V8 engines in which the connecting rod or crankshaft components can fail, ending in engine failure. The other describes brake control module software that may fail to display the low brake fluid warning lamp, so a driver may keep going with the level down and less braking than expected. Of 67 owner complaints, 31 name the engine, 11 the electrical system and 9 the power train. Engine internal specifications, brake diagnostics and body electrical wiring diagrams are all included.
