Varies by engine and year, but typically in the range of 140-170 HP and 200-250 lb-ft torque for the 5.9L V8, and 170-190 HP for the 4.0L I6.
Fuel Delivery Type:
Fuel Injection (Throttle Body Injection - TBI, or Multi-Port Fuel Injection - MPFI in later years) and Carbureted (earlier models).
Engine Family:
AMC V8 (318, 360) and AMC Inline-6 (242 - 4.0L HO).

Pressurized liquid cooling system with engine-driven fan.
Standard Transmission:
4-speed Manual (e.g., NP435) was available on some models, especially earlier ones.
Automatic Transmission:
3-speed Automatic (e.g., TF-999, TF-904) and 4-speed Automatic (e.g., AW4) depending on engine and specific model year.
Drivetrain Configuration:
Full-time 4-Wheel Drive (4WD) with a 2-speed transfer case (e.g., NP228, NP229, NP242 Selec-Trac) was standard on most models.
Wheelbase:
Approximately 108.7 inches (2761 mm).
Overall Length:
Approximately 176.7 inches (4488 mm).
Cargo Volume:
Significant cargo space due to station wagon design, typically exceeding 80 cubic feet with rear seats folded.
Curb Weight:
Approximately 4,200 - 4,800 lbs (1905 - 2177 kg), depending on configuration and engine.
Audio System:
Factory-installed AM/FM radio with cassette player. Optional premium sound systems were available.
Climate Control:
Manual HVAC systems with optional air conditioning.
Driver Assistance Features:
Very limited by modern standards. ABS available on later models. No electronic stability control or advanced driver aids.
Connectivity Options:
N/A (No integrated Bluetooth, USB ports, or smartphone integration).
Oil Change Interval:
Typically every 3,000 to 5,000 miles (4,800 to 8,000 km), depending on driving conditions and oil type used. Refer to manual for exact recommendations.
Tune Up Interval:
Spark plugs, ignition wires, distributor cap, and rotor should be inspected/replaced as needed, typically every 30,000 miles (48,000 km).
Engine Oil Specification:
API Service SG or higher, viscosity typically 10W-30 or 10W-40. Always consult manual for precise specification.
Coolant Specification:
Ethylene glycol based antifreeze, mixed with distilled water (50/50 ratio). Refer to manual for approved types.
Automatic Transmission Fluid:
ATF+3 or equivalent (e.g., Dexron III, Mercon compatible) for models equipped with Chrysler automatic transmissions. For Jeep's specific transmissions, consult the manual.
Transfer Case Fluid:
Typically a specialized gear oil or ATF, depending on the transfer case model (e.g., NP228/229 often used Dexron II/III).
Brake Fluid Specification:
DOT 3 or DOT 4 brake fluid, depending on specific brake system components. Refer to manual for exact specification.
Common Wear Items:
Leaf spring bushings, shock absorbers, steering box wear, rust (especially on body panels and frame), exhaust system deterioration, radiator leaks, fuel pump issues, ignition system components.
Engine Specific Issues:
AMC V8s are generally robust but can develop oil leaks. AMC inline-6 (4.0L) known for durability but can suffer from head gasket issues if overheated.
Electrical Issues:
Corrosion in wiring harnesses, faulty grounds, and aging electrical components (alternator, starter, switches) can be common.
Jeep Legacy:
The Jeep brand is renowned for its off-road prowess and utility, established during WWII. The Wagoneer extended this legacy into the luxury SUV segment.
Wagoneer Evolution:
The SJ Wagoneer platform debuted in 1963 and underwent significant updates over its long production run. The years 1984-1996 represent the final iterations of this iconic, body-on-frame SUV before the Grand Cherokee (ZJ) and the new generation Wagoneer (Grand Wagoneer ZJ and later models) took over. Key updates in this period included the introduction of more fuel-efficient engines and updated interior/exterior styling.
Manufacturing Location:
United States (primarily Toledo, Ohio).
Production Period:
The SJ Wagoneer was produced from 1963 to 1991. The models covered from 1991-1996 refer to the Grand Wagoneer (ZJ platform) which shared some design lineage but was a distinct generation. However, the manual title clearly states 'Wagoneer 1984-1996', implying it covers the later SJ Wagoneer and potentially the early ZJ Grand Wagoneer if there's overlap or a combined manual.
