Engine Type:
Likely a four-cylinder gasoline (e.g., 2.5L 200tdi, 2.25L Petrol, or similar) or a diesel engine (e.g., 2.5L Diesel, 200Tdi).
Engine Code Example:
Examples for 1986 might include 12J (2.5L Diesel), 19J (2.5L Turbo Diesel), or various gasoline variants. Specific code depends on market.
Horsepower Range:
Typically in the 60-100 HP range depending on engine and configuration.
Torque Range:
Typically in the 100-170 lb-ft range.

Approx. 3,500 - 4,000 lbs (1,600 - 1,800 kg) depending on body style and engine.
Crash Test Data:
For 1986 vehicles, formal crash test ratings as understood today were less standardized. The design prioritizes robustness and off-road capability.
Braking System Type:
Typically front disc brakes and rear drum brakes, with a hydraulic system.
Seat Belts:
Standard seat belts; three-point belts may be present depending on the specific trim and market.
Chassis Construction:
Body-on-frame construction for robustness.
Audio System:
Basic AM/FM radio, possibly with cassette player, as an optional upgrade. Not a sophisticated infotainment system by modern standards.
ABS:
Anti-lock Braking System (ABS) was not standard or widely available on 1986 models, but could be an optional feature on some late production/export models.
Connectivity Features:
None by modern definition. Basic electrical systems for lighting, ignition, and auxiliary power.
Oil Change Interval Engine:
Typically every 3,000-5,000 miles (4,800-8,000 km) or 6-12 months, depending on usage and engine type.
Gearbox Oil Change:
Recommended at intervals specified in the manual, often around 20,000-30,000 miles (32,000-48,000 km).
Engine Oil Type:
Recommended oils will vary based on engine type (petrol/diesel) and climate, but likely 10W/40 or 15W/40 (e.g., API CD/SF or higher for diesel, API SF/SG for petrol).
Coolant Type:
Ethylene glycol based antifreeze, typically a 50/50 mix with distilled water. Manual will specify exact type and capacity.
Gearbox Oil Type:
Likely a GL-4 or GL-5 rated manual transmission fluid (e.g., SAE 75W-90 or 80W-90).
Transfer Case Oil Type:
Similar to gearbox oil, likely GL-4 or GL-5 rated fluid, specific grade will be in manual.
Axle Differential Oil Type:
Hypoid gear oil, typically SAE 80W-90 or 85W-140, often GL-5 rated, with limited-slip additive if applicable.
Common Wear Items:
Bushings (suspension, steering), U-joints, wheel bearings, clutch wear, rust (body and chassis), alternator, starter motor, radiators.
Engine Specific Concerns:
Oil leaks, gasket failures, turbocharger wear (on Tdi models), injector issues (diesel).
Land Rover Legacy:
The Defender is a direct descendant of the original Land Rover Series I, II, and III, renowned for its ruggedness, off-road prowess, and utilitarian design.
Defender Era:
The Defender name was officially adopted in 1990, but the 1986 model represents the continuation of the Series Land Rover lineage with modernizations like coil springs and updated powertrains.
Production Location:
Solihull, United Kingdom.
Significant Changes Around 1986:
The mid-1980s saw the introduction of coil springs, a new 5-speed gearbox (LT77), and improved engine options, including turbo-diesel variants.
