The 2010 GMC Acadia comes equipped with a 3.6L DOHC V6 engine, also known as the LLT engine code. This naturally aspirated engine produces 288 horsepower and 270 lb-ft of torque, paired with a 6-speed automatic transmission. The engine features direct injection technology, variable valve timing on both intake and exhaust camshafts, and aluminum construction for weight savings. It’s designed to run on regular unleaded gasoline and provides a good balance of power and fuel economy for a three-row crossover SUV of this size and weight class.

The 2010 GMC Acadia shares most parts with the 2009-2017 model years of the first-generation Acadia. Many components are also interchangeable with the Chevrolet Traverse (2009-2017) and Buick Enclave (2008-2017) as they share the same Lambda platform. The 3.6L engine parts are compatible across these years, though there were minor updates in 2013. Body panels, interior components, suspension parts, and most mechanical components interchange well within this generation. However, always verify part numbers as there were running changes and option-specific variations throughout the production run.

The 3.6L V6 in the 2010 Acadia is moderately reliable but has some known weaknesses. The timing chain system is the biggest concern, with stretch and failure common after 80,000 miles. Regular oil changes with the correct viscosity are crucial for timing chain longevity. The engine also requires premium attention to carbon buildup on intake valves due to direct injection. When properly maintained with quality oil and regular service intervals, these engines can reach 200,000+ miles. However, neglected maintenance or ignoring timing chain rattle can lead to expensive repairs or complete engine failure.
