Engine Options:
Primarily 5.9L (360 cu in) V8, with potential for 4.2L (258 cu in) inline-6 and 5.9L Turbo Diesel in earlier SJ models, though the manual specifically covers 1984-1996 which predominantly featured the V8.
Horsepower Torque:
Varies by year and specific engine tune, but typically in the range of 140-170 HP and 220-260 lb-ft of torque for the 5.9L V8 in this era.
Fuel Delivery:
Throttle Body Injection (TBI) or Multi-Point Fuel Injection (MPI) depending on the specific year within the 1984-1996 range. The manual covers these systems.
Carburetor Options:
Early models in this range (e.g., early 80s) may still utilize carburetors like the Rochester Quadrajet or Motorcraft 4350, while later models adopt fuel injection. Manual coverage is comprehensive for both.
Displacements:
Primarily 5.9L (360 ci) V8. Earlier models had 4.2L (258 ci) I6. Manual covers the specified years.
Transmission Type:
Automatic transmission is standard on most Wagoneer SJ models in this period, commonly the TF727 TorqueFlite (3-speed) or A727 variants.
Manual Transmission:
Manual transmissions (e.g., NP435 4-speed) were available in earlier models but less common by the late 1980s/early 1990s. The manual likely covers any variants offered within the specified years.
Drivetrain:
Full-time 4-wheel drive (4WD) with Quadra-Trac transfer case is a hallmark of the Wagoneer SJ.
Transfer Case Details:
Quadra-Trac full-time 4WD system, often with a selectable low-range or full-time viscous coupling. Manual details its operation and service.
Oil Change Interval:
Typically every 3,000 miles or 3 months for this era of vehicle, though synthetic oils could extend this. Refer to specific manual section for precise intervals.
Transmission Fluid Change:
Typically every 30,000 to 60,000 miles, depending on driving conditions. Manual specifies intervals.
Differential Fluid Change:
Recommended every 30,000 to 50,000 miles or annually. Manual provides specific guidance.
Cooling System Flush:
Recommended every 2-3 years or 30,000 miles. Manual details procedure and coolant type.
Engine Oil:
Commonly 10W-30 or 10W-40 API Service SG or higher for the V8 engines. Specific viscosity and API rating should be confirmed in the manual.
Transmission Fluid:
Chrysler ATF+3 or equivalent for TF727/A727 transmissions. Manual will provide specific part numbers or equivalents.
Coolant:
Ethylene glycol-based antifreeze (green) with distilled water, typically a 50/50 mix. Manual will specify correct type and capacity.
Brake Fluid:
DOT 3 brake fluid is standard. Manual will confirm specific type and bleeding procedures.
Power Steering Fluid:
Typically Dexron III or equivalent power steering fluid. Manual will provide exact specification.
Differentials:
Hypoid gear oil (e.g., SAE 90) for front and rear differentials. Manual will specify GL rating and capacities.
Common Problems:
Rust (especially body panels, frame rails, and wheel wells), aging electrical components, carburetor/fuel injection issues, worn suspension bushings, and drivetrain wear are common. The manual's troubleshooting section would address these.
Common Engine Problems:
Carburetor wear, vacuum leaks, aging fuel pump, and potential internal wear on higher mileage engines. Manual details diagnostics.
Common Transmission Problems:
Slipping gears, torque converter issues, and leaky seals in automatic transmissions. Manual guides repair.
Spark Plugs:
Specific gap and type (e.g., Champion, AC-Delco) vary by engine. Manual will provide precise specifications.
Jeep Legacy:
The Wagoneer SJ is a foundational model in the SUV segment, originating from the Jeep lineage with a reputation for ruggedness and off-road capability.
Sj Platform:
The SJ platform, introduced in 1974, represented a more comfortable and refined evolution of the original Wagoneer, continuing Jeep's tradition of premium 4x4 vehicles. The 1984-1996 period represents the final iteration of this iconic SJ platform before its discontinuation.
Discontinuation Impact:
The SJ platform's long production run and subsequent discontinuation mean that factory service information is crucial for ongoing maintenance and restoration efforts.
Production End:
The SJ Wagoneer was last produced in 1991 in North America, with the Grand Wagoneer continuing until 1993. However, the manual explicitly lists coverage up to 1996, suggesting it may cover some later production models or specific markets where production extended, or it encompasses a comprehensive historical dataset for this platform's final years.
