The Jeep Grand Cherokee II (WJ), produced from 1999 to 2004, represented a significant leap forward for the iconic American SUV. The 4.7 HO V8 4×4 Automatic variant, specifically manufactured from 2001 to 2003, occupied a prominent position in the lineup, offering a blend of power, capability, and relative luxury. This model aimed to provide buyers with a robust, all-terrain vehicle without the premium price tag of the top-tier trims. It served as a strong competitor in the mid-size SUV segment, appealing to those needing towing capacity and four-wheel drive for both on and off-road adventures.

INTRODUCTION
The 4.7-liter High Output (HO) V8 engine, paired with a four-speed automatic transmission, was introduced in the WJ Grand Cherokee in 2001 as a replacement for the previous 4.0L inline-six and 4.7L non-HO V8. This combination offered a substantial power increase, making it a popular choice for those who frequently towed or ventured off-road. Positioned between the base 3.7L V6 and the high-performance 4.7L V8, the HO model struck a balance between affordability and capability. The WJ generation itself was a major redesign for the Grand Cherokee, featuring a fully independent front suspension, improving ride quality and handling compared to its predecessor.
Powertrain & Engine Architecture
The 4.7 HO V8, designated as the EVC engine code, is a 90-degree OHV (Overhead Valve) engine. It featured multi-port fuel injection and a cast iron block with aluminum cylinder heads. The engine produced 265 horsepower at 5200 rpm and 325 lb-ft of torque at 3600 rpm. The 42RE four-speed automatic transmission was specifically chosen for its durability and ability to handle the engine’s torque output. This transmission utilized electronic controls for smoother shifting and improved fuel efficiency. While not the most technologically advanced transmission available at the time, it proved to be reliable and capable for the intended application. The engine’s design prioritized low-end torque, making it well-suited for towing and off-road driving.
Driving Characteristics
The 4.7 HO V8 Automatic Grand Cherokee offered a noticeable improvement in acceleration compared to the lower-powered engine options. While not a sports car, it provided ample power for merging onto highways and passing other vehicles. The four-speed automatic transmission, while adequate, wasn’t known for its quick shifts. The gear ratios were optimized for towing and off-road performance, resulting in a slightly less responsive feel than the manual transmission variants. The 4×4 system, utilizing a part-time transfer case, allowed drivers to switch between two-wheel drive and four-wheel drive as needed, providing enhanced traction in challenging conditions. The vehicle’s substantial weight (approximately 4,080 lbs) did impact overall agility, but the robust suspension system helped to mitigate body roll.
Equipment & Trim Levels
The 4.7 HO V8 typically came standard with features such as air conditioning, power windows and locks, cruise control, and an AM/FM stereo with a CD player. Higher trim levels, like the Limited, added features such as leather upholstery, heated seats, a premium sound system, and automatic climate control. Optional extras included a sunroof, navigation system, and upgraded wheels. The interior design was functional and comfortable, though not particularly luxurious compared to some competitors. The 4.7 HO models often featured unique badging and exterior trim to distinguish them from the base models.
Chassis & Braking
The WJ Grand Cherokee featured a fully independent front suspension with coil springs and a rigid rear axle with coil springs and a trailing arm setup. This suspension configuration provided a comfortable ride and decent off-road capability. The 4.7 HO models were equipped with ventilated disc brakes on all four wheels, providing adequate stopping power for the vehicle’s weight. An Anti-lock Braking System (ABS) was standard, enhancing safety during emergency braking situations. The steering system utilized a recirculating ball mechanism, offering a solid and predictable feel.
Market Reception & Comparison
The 4.7 HO V8 Grand Cherokee was generally well-received by automotive critics. It was praised for its powerful engine, comfortable ride, and capable four-wheel drive system. However, some reviewers noted the transmission’s lack of responsiveness and the vehicle’s relatively poor fuel economy (15 mpg combined). Compared to the 3.7L V6, the 4.7 HO offered a significant performance upgrade, but at a higher price point. Compared to the higher-output 4.7L V8, the HO model provided a more affordable option with slightly less power. The 4.7 HO was often seen as a sweet spot in the Grand Cherokee lineup, offering a good balance of performance, features, and value.
Legacy
The 4.7 HO V8 engine, while not without its flaws, proved to be a relatively reliable powertrain. Common issues included oil leaks and occasional sensor failures, but these were generally not major concerns. Today, the 4.7 HO Grand Cherokee is a popular choice among used car buyers looking for a capable and affordable SUV. Its robust construction and readily available parts make it a relatively easy vehicle to maintain. While fuel economy is not its strong suit, its overall dependability and off-road prowess continue to make it a desirable vehicle for those seeking a classic American SUV.
