Engine Options Early:
2.5L AMC I4 (150 cu in) OHV, 4.0L AMC I6 (242 cu in) OHV
Engine Options Later:
Continued with 2.5L I4 and 4.0L I6. The 4.0L I6 became particularly renowned for its torque and durability.
4.0L I6 Hp:
Approximately 173-177 hp (varies slightly by year and tune)
4.0L I6 Torque:
Approximately 220-225 lb-ft (varies slightly by year and tune)
Fuel Delivery:
Multi-point fuel injection (MPI) for most models, especially later ones within this range. Early models may have had throttle body injection (TBI) or carburetor variants for the 2.5L.
Oil Change Interval:
Typically every 3,000 - 5,000 miles, or 6 months (depending on oil type and driving conditions). Consult manual for specific recommendations.
Transmission Fluid Change:
Automatic: 30,000 - 60,000 miles. Manual: Varies, often longer intervals. Consult manual for specific ATF type and interval.
Coolant Change Interval:
Typically every 2 years or 30,000 miles for conventional coolant, longer for extended-life coolants.
Engine Oil Specification:
API Service SG or SH, SAE 10W-30 or 10W-40 (check manual for ambient temperature specific viscosity recommendations). 4.0L I6 capacity: 6 US quarts with filter.
Automatic Transmission Fluid:
ATF+3 or ATF+4 (later spec, check for compatibility with original spec for AW4, TF-904/999) - consult manual for exact specification for each transmission type.
Coolant Specification:
Conventional green ethylene glycol based coolant. 50/50 mix with distilled water. Capacity approx. 10-12 quarts depending on engine/radiator size.
Power Steering Fluid:
Mopar Power Steering Fluid or ATF+3 (check manual). Capacity approx. 1-1.5 quarts.
Common Xj Issues Early:
Cooling system leaks (radiator, water pump), rear main seal leaks (4.0L I6), exhaust manifold cracks (4.0L I6), interior electrical gremlins, rust on unibody structure (rocker panels, unibody rails), aging suspension bushings, worn U-joints, starter solenoid issues.
Engine Wear Points:
Valve stem seals, oil pump pickup screen clogging (4.0L I6), timing chain wear (less common in I6 but possible).
Jeep Heritage:
Building on Jeep's legacy of rugged, go-anywhere vehicles, the XJ Cherokee was a significant evolution, blending utility with newfound comfort and refinement.
Xj Introduction:
Introduced in 1984, the XJ Cherokee revolutionized the SUV market with its unibody construction, setting it apart from body-on-frame competitors. It was the first compact SUV and offered a more car-like ride than traditional Jeeps.
Key Changes 1984-1993:
The period covers the initial launch and early refinements. Key updates within this range included the introduction of the legendary 4.0L I6 engine in 1987, significant interior and exterior styling tweaks, and the addition of optional features like ABS and improved fuel injection systems.
Manufacturing Location:
Primarily Toledo, Ohio, USA.
