The 2000 Toyota 4Runner comes equipped with Toyota’s 3.4L V6 engine, designated as the 5VZ-FE. This naturally aspirated, dual overhead cam engine produces 183 horsepower at 4,800 RPM and 217 lb-ft of torque at 3,600 RPM. The engine features aluminum heads with iron block construction, multi-port fuel injection, and a timing belt-driven valvetrain. This powerplant was paired with either a 5-speed manual transmission or 4-speed automatic, and was available in both 2WD and 4WD configurations. The 3.4L V6 was known for its smooth operation and adequate power for both daily driving and light off-road use, making it a popular choice among 4Runner enthusiasts.

The 2000 Toyota 4Runner shares most parts with the 1996-2002 third-generation 4Runner models. Engine components from the 3.4L V6 are largely interchangeable across these years, with some minor variations in sensors and emissions components. Body panels, interior trim, and suspension components are generally compatible within the 1999-2002 model years due to the mid-cycle refresh. The transmission, transfer case, and differential components are typically interchangeable across the entire 1996-2002 generation. Some electrical components and ECU modules may have year-specific variations, particularly between pre-1999 and post-1999 models. Always verify part numbers when sourcing critical components like airbag modules, ABS controllers, or engine management systems.

The 3.4L V6 in the 2000 4Runner is generally considered a reliable and durable engine when properly maintained. With regular oil changes every 5,000 miles and timing belt replacement every 90,000 miles, these engines commonly exceed 250,000 miles. The main weakness is the timing belt system, which requires diligent maintenance as this is an interference engine that can suffer valve damage if the belt breaks. Head gasket issues can occur at higher mileages but are less common than in some other Toyota engines of this era. The engine responds well to regular maintenance and quality fluids. Key maintenance items include timing belt service every 90,000 miles, regular coolant flushes, and monitoring for any external oil or coolant leaks as the vehicle ages.
