The 2004 Toyota Tacoma came with two engine options: a 2.4L 4-cylinder (2RZ-FE) producing 142 horsepower, and the more popular 3.4L V6 (5VZ-FE) producing 190 horsepower and 220 lb-ft of torque. The 3.4L V6 was available in both 2WD and 4WD configurations and could be paired with either a 5-speed manual or 4-speed automatic transmission. This engine features an aluminum head with iron block construction, timing belt operation, and multi-port fuel injection. It’s known for its smooth power delivery and decent fuel economy for a V6 of that era, typically achieving 18-22 mpg combined depending on transmission and drivetrain configuration.

The 2004 Toyota Tacoma shares most parts with the 1995-2004 first-generation Tacoma models, though some components changed during mid-cycle refreshes. Engine parts from the 3.4L V6 are compatible across all years it was offered (1995-2004 Tacoma, 1996-2002 4Runner). Body panels and interior components generally interchange within the 2001-2004 facelifted models, while 1995-2000 models have different front-end styling. Suspension components, drivetrain parts, and most mechanical systems are largely interchangeable across the entire first generation. However, always verify part numbers as Toyota made running changes throughout production, particularly for emissions components and electrical systems.

The 3.4L V6 (5VZ-FE) is generally considered one of Toyota’s most reliable engines, often lasting 250,000+ miles with proper maintenance. Key maintenance includes timing belt replacement every 90,000 miles (critical as this is an interference engine), regular oil changes every 5,000 miles, and coolant system maintenance. Common issues include timing belt tensioner failure, water pump leaks around 100,000 miles, and occasional head gasket seepage. The engine is known for its smooth operation and consistent power delivery. Most failures occur due to deferred maintenance rather than design flaws. With proper care, these engines routinely exceed 300,000 miles, making them excellent candidates for rebuilds and swaps.
