⚙️ Engine Specifications

Engine Options:

The manual explicitly mentions a '2.5L Diesel Engine'. It is highly probable that this manual also covers gasoline engines common to the WJ Grand Cherokee, such as the 4.0L Inline-6 and the 4.7L V8. Specific details would need to be verified within the manual's engine section.

Typical Performance Indicators:

Horsepower and torque figures vary significantly by engine. The 4.0L inline-six typically produced around 190 hp and 235 lb-ft of torque, while the 4.7L V8 offered around 230 hp and 325 lb-ft of torque. The 2.5L Diesel performance would be specific to that variant.

Fuel Delivery:

Likely multi-point fuel injection (MPI) for gasoline engines. Diesel would be direct injection or common rail depending on the specific 2.5L variant. Manual will detail fuel pump operation, injectors, fuel lines, and pressure regulation.

2 5L Diesel Specifics:

The manual's explicit mention of the 2.5L Diesel Engine suggests detailed coverage of its fuel injection system, glow plug system, exhaust manifold, and any specific maintenance or repair procedures related to this engine variant.

🔧 Transmission

Standard Transmission:

The WJ Grand Cherokee was predominantly offered with automatic transmissions. The most common would be the 4-speed automatic 42RE or 45RFE/4545RFE depending on the engine and year.

Optional Transmission:

While manual transmissions were rare on later Grand Cherokees, earlier models sometimes offered them. The manual's coverage of clutch systems suggests the possibility of manual transmission information, though its prevalence in the WJ generation is less common. It's important to note that the 1992 model year is unusual for the WJ generation which officially debuted in 1999. This product listing may contain an error in the model year or refer to an earlier Grand Cherokee generation (like the ZJ).

Transfer Case:

The manual lists 'Transfer Case', indicating coverage of systems like the NV231, NV242 Selec-Trac, or NV247 Quadra-Trac II, which were common on Grand Cherokees.

📐 Dimensions

Wheelbase:

Approximately 110.0 inches (2794 mm) for WJ generation.

Length:

Approximately 184.0 inches (4674 mm) for WJ generation.

Width:

Approximately 73.5 inches (1867 mm) for WJ generation.

Height:

Approximately 66.1 inches (1679 mm) for WJ generation.

Curb Weight:

Varies by engine and drivetrain, typically ranging from 4,200 to 4,800 lbs (approx. 1900-2200 kg).

🛡️ Safety Features

NHTSA Crash Test Results:

Specific NHTSA ratings for the 1992 model year would need to be consulted from historical databases. Later WJ models generally performed acceptably for their era.

Active Safety:

ABS (Anti-lock Braking System) likely standard or optional depending on trim. Four-wheel drive systems (Quadra-Trac, Quadra-Drive) also contribute to active safety.

Passive Safety:

Airbags (driver and passenger), seat belts with pretensioners, crumple zones, reinforced body structure.

💡 Technology Features

Audio Systems Coverage:

The manual explicitly covers 'Audio Systems', indicating detailed information on factory radios, speaker systems, amplifiers, and antenna systems, including troubleshooting and repair.

Instrument Panel Systems:

Coverage of instrument panel systems includes detailed information on gauges, warning lights, and diagnostic indicators, crucial for identifying vehicle faults.

Vehicle Speed Control:

Coverage of the Vehicle Speed Control System (cruise control) is listed, detailing its operation, components, and troubleshooting.

Wiring Diagrams Importance:

The inclusion of 'Wiring Diagrams' is critical for understanding the vehicle's electrical architecture, essential for diagnosing and repairing any electronic or communication-related issues.

🔧 Maintenance

Oil Change Interval:

Typically 3,000-7,500 miles (5,000-12,000 km) or 6-12 months, depending on oil type and driving conditions. The manual will provide precise recommendations.

Transmission Fluid Change:

Recommended every 30,000-60,000 miles (50,000-100,000 km). Fluid type and procedure are critical and will be detailed in the manual.

Engine Oil Specification:

Likely SAE 5W-30 or 5W-40 for gasoline engines, and specific diesel engine oil for the 2.5L diesel. Manual will specify API service classification (e.g., API SN, CJ-4).

Coolant Specification:

Typically a 50/50 mix of ethylene glycol based antifreeze and deionized water. The manual will specify the correct type (e.g., HOAT or OAT) and color.

Brake Fluid Specification:

DOT 3 or DOT 4 brake fluid, depending on the vehicle's braking system components. Manual will confirm.

Power Steering Fluid Specification:

Likely ATF+4 or a specific power steering fluid. Manual will specify.

Transfer Case Fluid:

The manual will specify the correct fluid type (e.g., ATF+4, NV247 special fluid) and capacity for the transfer case.

Differential Fluid:

Manual will detail the required gear oil viscosity (e.g., 75W-90, 80W-90) and capacity for both front and rear differentials, and if limited-slip additives are required.

Common Wj Problems:

While not detailed in the product description, common issues for the WJ generation (and potentially earlier models) can include: radiator leaks, heater core failure, transmission solenoid issues, transfer case chain stretch, various electrical gremlins, and potential differential pinion seal leaks. The manual would be invaluable for diagnosing and repairing these.

Clutch System Maintenance:

The inclusion of a 'Clutch' section indicates that while automatic transmissions were prevalent, the manual may cover clutch maintenance for any manual variants or related clutch-actuated systems.

📚 Vehicle History

Jeep Legacy:

Jeep has a long-standing reputation for robust off-road capability and durable SUVs, dating back to its military origins.

Grand Cherokee Lineage:

The Grand Cherokee was introduced in 1993 as a more luxurious and comfortable alternative to the Cherokee (XJ). The WJ generation (1999-2004) represented a significant redesign with improved on-road manners and refined interiors.

Wj Generation Significance:

The WJ was praised for its improved ride quality, quieter cabin, and more sophisticated interior compared to its predecessor (ZJ), while retaining strong off-road credentials with available advanced 4x4 systems.

Manufacturing Locations:

Primary manufacturing was in Jefferson North Assembly, Detroit, Michigan.

Model Year Discrepancy:

The listed model year of '1992' for the WJ Grand Cherokee is highly anomalous. The WJ generation officially debuted for the 1999 model year. The first generation Grand Cherokee (ZJ) ran from 1993 to 1998. It is possible the manual is mislabeled or refers to a very early prototype or a different model altogether. Assuming the 'WJ' designation is correct, the year is almost certainly a typo and should be 1999 or later.
