The 2006 Toyota Highlander comes with a 3.3L V6 engine (3MZ-FE), producing 215 horsepower and 222 lb-ft of torque. This naturally aspirated DOHC engine features aluminum construction with iron cylinder liners and Toyota’s VVT-i variable valve timing system. The engine is paired with a 5-speed automatic transmission and is available in both front-wheel drive and all-wheel drive configurations. This powerplant provides adequate performance for the mid-size SUV, offering a good balance of power and fuel economy for its class during this generation.

The 2006 Toyota Highlander shares most parts with the 2001-2007 first-generation models, as this represents a single generation with only minor updates. The 3.3L V6 engine components are largely interchangeable across these years, though early 2001-2003 models had slightly different emissions equipment. Body panels, interior components, and suspension parts are generally compatible within this generation. However, 2004-2007 models received a facelift with updated front and rear styling, so some exterior trim pieces differ. Always verify part numbers when sourcing components, as running changes occurred throughout production.

The 3.3L 3MZ-FE V6 engine is generally reliable when properly maintained, but has some known weaknesses. With regular oil changes using quality oil, these engines can easily reach 200,000+ miles. However, they are susceptible to oil consumption issues and sludge buildup if maintenance is neglected. The timing chain system is robust and doesn’t require replacement like timing belts. Key maintenance includes frequent oil changes (every 5,000 miles), regular coolant flushes, and monitoring for oil consumption. Avoid extended oil change intervals to prevent catalytic converter damage and internal engine problems.
