The Ford Explorer II, specifically the 4.0 V6 variant producing 155 horsepower, represents a significant iteration in Ford’s popular SUV lineage. Produced from 1995 to 2003, this second-generation Explorer (designated as the U2 platform) aimed to refine the formula established by the original, offering increased space, improved comfort, and a more modern driving experience. The 4.0L V6, 155 hp configuration occupied a middle ground in the Explorer II lineup, positioned between the base 4.0L SOHC engine and the more powerful 5.0L V8 options. It was targeted towards buyers seeking a balance of capability and affordability.

Powertrain & Engine Architecture
The heart of this Explorer II variant is the 4.0-liter Cologne V6 engine. This engine, internally designated as the 4.0L OHV, is a pushrod engine, a design choice that prioritized compactness and cost-effectiveness over the more complex overhead cam configurations. The engine features a 90-degree V-angle, contributing to a smoother running character. Fuel delivery is managed by a multi-port fuel injection system, providing precise fuel metering for improved efficiency and emissions control. The 155 horsepower output is achieved at 4200 rpm, while peak torque of 298 Nm (219.79 lb-ft) arrives at 2400 rpm. This torque curve provides adequate low-end grunt for everyday driving and towing. The engine is paired with a 5-speed manual transmission, delivering power to the rear wheels. While an automatic transmission was available, the manual offered a more engaging driving experience and slightly improved fuel economy.
Driving Characteristics
The 155 hp 4.0L V6 with a manual transmission provided a reasonably spirited driving experience for its time. Acceleration was adequate for merging onto highways and passing slower traffic, but it wasn’t a particularly quick vehicle. The manual transmission allowed drivers to keep the engine in its optimal power band, maximizing performance. The gear ratios were well-suited for both city and highway driving, offering a balance of responsiveness and fuel efficiency. Compared to the 5.0L V8 models, the 4.0L V6 felt less powerful, but it also offered better fuel economy and a lighter front end, contributing to more balanced handling. The leaf spring rear suspension, while robust, could result in a somewhat bouncy ride, especially when carrying heavy loads.
Equipment & Trim Levels
The Explorer II 4.0L V6 typically came standard with features such as air conditioning, power windows and locks, and an AM/FM stereo. Higher trim levels, like the XLT and Limited, added features such as alloy wheels, upgraded interior upholstery, a sunroof, and a premium sound system. Optional extras included leather seats, a CD player, and a tow package. The interior design was functional and durable, with a focus on practicality rather than luxury. The dashboard layout was straightforward and easy to use, with clearly labeled controls.
Chassis & Braking
The Explorer II utilized a body-on-frame construction, providing a robust and durable platform. The front suspension consisted of coil springs and independent control arms, while the rear suspension employed leaf springs and a solid axle. This configuration was chosen for its load-carrying capacity and off-road capability. Braking duties were handled by disc brakes at the front and drum brakes at the rear. An anti-lock braking system (ABS) was available as an option, enhancing safety and control during emergency braking situations. The steering system was a rack-and-pinion setup with hydraulic power assist, providing responsive and precise steering feel.
Market Reception & Comparison
The Explorer II 4.0L V6 was generally well-received by critics and consumers alike. It was praised for its spacious interior, comfortable ride, and reasonable fuel economy. However, some critics noted that the engine lacked the power of the V8 options and that the leaf spring rear suspension could result in a somewhat harsh ride. Compared to competitors such as the Chevrolet Blazer and the Jeep Grand Cherokee, the Explorer II offered a compelling combination of features, value, and reliability. The 4.0L V6 provided a good balance between performance and fuel efficiency, making it a popular choice for families and individuals who needed a versatile and capable SUV.
Legacy
The Ford Explorer II 4.0L V6 has proven to be a relatively reliable powertrain. The 4.0L V6 engine is known for its durability and longevity, and with proper maintenance, it can easily exceed 200,000 miles. However, like any older vehicle, it is prone to certain issues, such as oil leaks and timing chain wear. In the used car market today, the Explorer II 4.0L V6 remains a popular choice for buyers seeking an affordable and capable SUV. Its simple design and readily available parts make it relatively easy to maintain and repair. While it may not offer the same level of refinement or technology as modern SUVs, it still provides a comfortable and practical driving experience.
