⚙️ Engine Specifications

Engine Type:

Diesel (common for F70/F75/F77 in this era, though gasoline variants may exist in some markets). Specific engine codes like DL41, DL42, DL51 are typical for Daihatsu diesel engines of this period. Actual specifications would require consulting specific vehicle VIN or market documentation.

Displacement:

Common diesel engines of this era include 2.8 liters (e.g., DL51 engine code). Specific displacement for F70/F75/F77 in 1986 would be confirmed via VIN or specific model documentation, but generally in the 2.4L-2.8L range for diesel.

Horsepower Torque:

Not explicitly stated in product information, but typical for 2.8L diesel engines of the era would be in the range of 85-100 HP and 150-180 lb-ft of torque. Specific figures vary by engine code and market.

Fuel Delivery:

Diesel Injection (likely mechanical injection pump systems for 1986 models).

🔧 Transmission

Type:

Manual Transmission (common, often 5-speed). Automatic transmission may have been optional.

Type:

Automatic Transmission (likely available on some models).

Drive Modes:

Four-wheel drive (4WD) with selectable low range is a hallmark of the Fourtrak, enabling off-road capability. Manual operation of transfer case and hubs is typical.

📐 Dimensions

Body Style:

Rugged SUV/Off-roader, typically available in short-wheelbase (SWB) and long-wheelbase (LWB) configurations. Body styles may include 2-door or 4-door variants.

Wheelbase:

Varies by configuration (e.g., Short Wheelbase, Long Wheelbase). Specific lengths are not provided but are typical for compact to mid-size SUVs of the era.

Seating Capacity:

Varies by body style; typically 4-5 passengers for 2-door and 5-7 passengers for 4-door configurations.

Cargo Volume:

Significant for its class, particularly in LWB variants, designed for utility and carrying gear.

Curb Weight:

Likely in the range of 1700-2000 kg (3750-4400 lbs), depending on configuration and equipment.

🛡️ Safety Features

Crash Test Data:

Not readily available for 1986 models in modern rating systems. Safety features would be typical for the era.

Braking System:

Front Disc Brakes (common), Rear Drum Brakes. Anti-lock braking systems (ABS) were not common on this model.

Steering Type:

Recirculating ball steering system, possibly with power assist on higher trims or optional. Known for durability.

Restraint System:

Seat belts for all occupants. Airbags were not standard or available on this model.

💡 Technology Features

Audio System:

Basic AM/FM radio with cassette player. Speaker configuration would be minimal (e.g., 2 or 4 speakers).

Features:

None typical for the era. Focus is on mechanical capability and durability.

🔧 Maintenance

Oil Change:

Typically 5,000 km (3,000 miles) or 6 months for diesel engines, though the manual will provide precise intervals.

Fuel Filter:

Diesel fuel filter replacement typically every 10,000-15,000 km (6,000-10,000 miles) or as per manual recommendations, critical for diesel engine health.

Air Filter:

Air filter replacement typically every 15,000-20,000 km (10,000-12,000 miles) or more frequently in dusty conditions.

Engine Oil:

API CD or CE grade diesel engine oil, viscosity typically SAE 15W-40 or 10W-30 depending on climate. Manual to confirm specific grade and capacity.

Coolant:

Ethylene glycol-based antifreeze coolant mixed with distilled water in a 50/50 ratio. Capacity approximately 6-8 liters.

Transmission Fluid:

Manual transmission fluid (GL-4 rated) for the gearbox and transfer case. Automatic transmission fluid (Dexron II or equivalent) for automatic transmissions. Capacities vary.

Differential Fluid:

API GL-5 hypoid gear oil, typically SAE 80W-90. Front and rear differentials, and potentially manual locking hubs, will have specific fill points and capacities.

Common Wear Items:

Age-related issues such as suspension bushings, brake component wear, potential for injector pump issues on high-mileage diesel engines, rust in chassis and body panels, and aging electrical components. Overheating can occur if cooling system maintenance is neglected.

📚 Vehicle History
