Powertrain & Engine Architecture
The heart of the 1999-2002 Toyota 4Runner 3.4 V6 4×4 is the 5VZ-FE engine. This 3.4-liter, naturally aspirated V6 is a robust and well-regarded powerplant known for its durability. It features a cast iron block and aluminum cylinder heads, contributing to its longevity. The 5VZ-FE utilizes a multi-port fuel injection system, delivering fuel directly to each intake port for improved combustion efficiency. The engine employs a double overhead camshaft (DOHC) valvetrain, operating 24 valves (four per cylinder) to optimize airflow and enhance performance. The 5VZ-FE produces 183 horsepower at 4800 rpm and 294 lb-ft of torque at 3600 rpm. The manual transmission option featured a five-speed gearbox, providing drivers with direct control over gear selection.
Driving Characteristics
The 4Runner 3.4 V6 with a manual transmission offered a responsive and engaging driving experience. While not a sports car, the engine provided ample power for everyday driving and confident highway merging. The five-speed manual allowed drivers to maximize engine efficiency and control, particularly when tackling challenging terrain. The gear ratios were well-suited for both on-road and off-road conditions, providing a balance of acceleration and crawl capability. Compared to the base 2.7-liter four-cylinder engine, the 3.4 V6 offered a significant performance upgrade, making it a more desirable choice for those who frequently tow or venture off the beaten path. While the V6 wasn’t as fuel-efficient as the four-cylinder, the added power and capability were often considered a worthwhile trade-off.
Equipment & Trim Levels
The 1999-2002 Toyota 4Runner 3.4 V6 4×4 was typically offered in SR5 and Limited trim levels. The SR5 served as the mid-range option, featuring standard amenities such as air conditioning, power windows and locks, and an AM/FM stereo. The Limited trim added luxury features like leather upholstery, heated front seats, and a premium sound system. Optional extras included a sunroof, upgraded audio systems, and a rear limited-slip differential. Interior upholstery was typically cloth on the SR5 and leather on the Limited. The dashboard layout was functional and straightforward, prioritizing ease of use over flashy design.
Chassis & Braking
The 4Runner III utilized a body-on-frame construction, providing a robust and durable platform for off-road adventures. The front suspension featured a double wishbone design, while the rear employed an independent multi-link setup. This suspension configuration delivered a comfortable ride quality on paved roads while maintaining excellent articulation for off-road capability. Braking duties were handled by ventilated discs at the front and drum brakes at the rear. An Anti-lock Braking System (ABS) was standard, enhancing safety and control during emergency braking situations. The hydraulic power steering provided responsive and precise steering feel.
