🔧 Maintenance

Oil Change Interval:

Typically every 3,000 to 5,000 miles or 3-6 months, depending on driving conditions and oil type used. Consult manual for precise recommendations.

Transmission Fluid Change:

Automatic transmission fluid (ATF) and filter service generally recommended every 30,000 to 60,000 miles. Manual transmission fluid change intervals also vary.

Coolant Flush:

Typically every 30,000 to 50,000 miles.

Engine Oil Type:

API Service SG or SH, SAE 10W-30 (check owner's manual for specific viscosity and specifications).

Automatic Transmission Fluid:

ATF+4 (preferred) or equivalent spec like Mopar ATF+3. Consult manual for specific type.

Coolant Type:

Ethylene glycol-based coolant, typically a green or gold type. Consult manual for specific type and mixture ratio (50/50).

Power Steering Fluid:

Mopar power steering fluid or equivalent Dexron II/III ATF.

Common Problems:

The 4.0L engine is known for its durability but can suffer from head gasket issues (though less common on later models like '92), oil filter housing leaks, and rust in critical areas if not properly maintained. Electrical gremlins can occur over time, particularly with grounds and connectors. Transfer case chain stretch or wear can also be an issue.

Filter Part Numbers:

Oil filter (e.g., Mopar MO-090, Fram PH8A or equivalent). Air filter (e.g., Fram CA7274 or equivalent). Fuel filter (specific to engine and year). Transmission filter (e.g., for AW4, Fram CH10154 or equivalent).

📚 Vehicle History

Jeep Legacy:

Jeep has a long history rooted in robust off-road vehicles, tracing its origins back to WWII military vehicles. This heritage is reflected in the Cherokee's capability and durability.

Xj Generation Introduction:

The XJ Cherokee was introduced for the 1984 model year, pioneering the compact SUV segment with its unibody construction, offering a lighter and more car-like driving experience than traditional body-on-frame SUVs.

1992 Updates:

The 1992 model year was part of the XJ's second generation (1990-1996). Key updates around this period included refinements to the interior, optional airbags, and subtle exterior styling tweaks. The 4.0L inline-six engine was significantly refined and became the powertrain of choice for many.

Xj Unibody Significance:

The XJ's unibody design was revolutionary for SUVs at the time, combining body and frame into a single structure, which improved rigidity, reduced weight, and enhanced ride comfort compared to traditional body-on-frame SUVs.

Production Location:

Jeep vehicles, including the Cherokee XJ, were primarily manufactured in Toledo, Ohio, USA.

🏆 Awards & Recognition

Off Road Reputation:

The Jeep Cherokee XJ is highly regarded for its off-road capabilities, often winning accolades from off-road publications and enthusiasts for its solid axle (front), relatively compact size, and ruggedness, especially with the 4.0L engine.
