The 2009 GMC Yukon comes standard with a 5.3L V8 engine producing 320 horsepower and 335 lb-ft of torque. However, this particular vehicle is equipped with the optional 6.2L V8 engine, which generates 403 horsepower and 417 lb-ft of torque. This high-performance LS3-based engine features aluminum construction, variable valve timing, and Active Fuel Management technology for improved fuel economy during light-load conditions. The 6.2L was only available in the Denali trim level and represents the most powerful engine option available in the 2009 Yukon lineup.

The 2009 GMC Yukon shares most parts with the 2007-2014 GMT900 platform generation. Body panels, interior components, and many mechanical parts interchange across these years. The 6.2L engine components are compatible with 2009-2013 Yukon Denali, Escalade, and other GM vehicles using the same L9H engine code. Transmission parts from the 6L80E are compatible across 2007-2014 models. However, some electronic modules and trim pieces may have year-specific variations. Always verify part numbers and VIN compatibility, especially for airbag components, PCMs, and body control modules which may have programming differences between model years.

The 6.2L V8 is generally a robust engine when properly maintained, but it has one significant weakness: the Active Fuel Management system. AFM lifter failures are common and can cause catastrophic engine damage if ignored. Regular oil changes with quality oil and AFM-compatible additives are crucial. Many owners opt for AFM delete modifications to improve reliability. The engine responds well to premium fuel and benefits from regular carbon cleaning due to direct injection deposits. When the AFM system is addressed proactively, this engine can provide reliable service well beyond 200,000 miles with proper maintenance including timely oil changes, cooling system service, and fuel system cleaning.
