Engine Options 1986:
4.2L (258 cu in) AMC I6, 5.0L (304 cu in) AMC V8, 5.7L (350 cu in) Chevrolet V8 (often found in later models but could be present in modified 86s or specific configurations), 5.9L (360 cu in) AMC V8
Horsepower Torque Notes:
Specific figures vary by engine option and tuning; manual will provide exact specs for each.
Carburetor Types:
Likely Carter BBD 2-barrel for the 4.2L, possibly Motorcraft or Rochester for V8s. Electronic Fuel Injection (EFI) became more common in this era, so coverage for EFI systems is probable.
Type:
Typically breakerless electronic ignition systems (e.g., Prestolite, Ford Duraspark variants).
Manual Transmission Options:
BorgWarner T-18 (4-speed) or T-19 (4-speed with closer ratios) were common.
Automatic Transmission Options:
Chrysler TorqueFlite series (e.g., TF-999 3-speed, TF-727 3-speed) were prevalent.
Transfer Case:
New Process NP208 (part-time, gear-driven) or possibly the NP228/229 (full-time/selectable 4WD) depending on trim and options.
Crash Test Performance:
No modern crash test ratings available for this era of vehicle. Safety features were basic by today's standards.
Braking System Type:
Front disc brakes, rear drum brakes. Power assist standard.
Restraint System:
Seat belts (lap and shoulder belts for front occupants), padded dashboard, steering column.
Oil Change Interval:
Typically every 3,000 miles or 3 months, but the manual will specify exact recommendations based on usage.
Tune Up Interval:
Spark plugs, ignition timing, and carburetor adjustments typically recommended every 15,000-30,000 miles.
Engine Oil:
API Service Classification SF or SG, viscosity typically SAE 10W-30 or 10W-40. Manual will confirm exact specification.
Transmission Fluid Automatic:
Dexron-III (or equivalent ATF) for TorqueFlite transmissions.
Transmission Fluid Manual:
GL-4 or GL-5 gear oil for manual transmissions, specific viscosity will be detailed.
Coolant:
Ethylene glycol-based antifreeze, typically a 50/50 mix with distilled water. Manual will specify capacity and type.
Common Wear Items:
Carburetor issues (stalling, rough idle), ignition system components (distributor cap, rotor, coil), exhaust leaks, rust (especially on body panels and frame), fuel pump reliability, suspension bushings and ball joints.
Oil Filter Example:
Likely an AC-Delco PF2 or equivalent (e.g., Fram PH8A, Wix 51515) for the 4.2L inline-6. Manual will provide exact OE and cross-reference numbers.
Jeep Legacy:
Jeep's heritage of rugged, go-anywhere vehicles, established by the military Willys Jeep.
Wagoneer Lineage:
The Wagoneer (SJ platform) was introduced in 1963 as a premium, wood-panelled station wagon, evolving into the full-size SUV icon. The 1986 model represents a mature iteration of this design.
Manufacturer:
American Motors Corporation (AMC) at the time of this model's production.
