⚙️ Engine Specifications

Primary Engine

Engine Type:

Naturally aspirated Boxer (Flat) engine. Specific displacement likely in the 1.8L to 2.7L range for this era, depending on the exact RX variant. Common engines for the Leone/Loyale platform included the EA82 (1.8L) and EJ series (early EJ18, EJ22).

Engine Configuration:

Horizontally opposed (Boxer) cylinders, typically 4-cylinder. This provides a lower center of gravity for improved handling.

Performance

Horsepower:

Varies by year and specific engine. For the EA82, typically 90-100 hp. Later EJ series engines could offer more, potentially 100-130 hp for naturally aspirated versions. Turbocharged RX variants, if available, would have higher output.

Torque:

Varies by year and specific engine. Expect figures in the range of 100-130 lb-ft for the 1.8L EA82, increasing with larger displacements or turbocharging.

Fuel System

Fuel Delivery:

Early models may feature carburetor(s), while later models (especially from the late 1980s onward) transitioned to Electronic Fuel Injection (EFI) or Multi-Point Fuel Injection (MPFI).

Engine Code Identification

Engine Codes:

Likely to include EA82 (for 1.8L naturally aspirated and turbocharged) or early EJ series (EJ18, EJ22) engines. Specific designation for the RX variant might be an internal Subaru code.

Turbocharged Options:

Some 'RX' variants of Subaru models from this era may have featured turbocharged engines (e.g., turbocharged EA82), offering significantly enhanced performance. This manual would cover these specific turbocharged engine systems.

🔧 Transmission

Standard

Transmission Type:

Manual transmission typically standard, often with 5 speeds. Subaru's Symmetrical All-Wheel Drive system was usually integrated with manual transmissions.

Optional

Transmission Type Optional:

Automatic transmission, likely a 3-speed or 4-speed unit, may have been available as an option, often with AWD capabilities.

Features

Drivetrain:

Symmetrical All-Wheel Drive (AWD) is a hallmark of Subaru. The RX variant would almost certainly feature this, likely with a viscous coupling center differential. Some models may have offered a full-time AWD system or a selectable low-range gear depending on trim.

Fluid Specifications

Manual Transmission Fluid:

Typically GL-4 rated gear oil. Specific viscosity (e.g., 75W-90 or 80W-90) would be detailed in the manual. Capacity around 2.5 - 3.0 liters.

Automatic Transmission Fluid:

Likely Dexron-II or equivalent. Capacity around 3.5 - 4.5 liters. Specific type and change interval would be crucial for longevity.

📐 Dimensions

Exterior

Body Styles:

Likely available as a 2-door Coupe, 4-door Sedan, and 4-door Wagon. The 'RX' designation may have been applied to specific body styles or performance trims.

Wheelbase:

Varies by body style and generation. For the Leone/Loyale platform, typical wheelbases range from approximately 96.5 inches (2450 mm) to 104.3 inches (2650 mm).

Track Width:

Specifics would depend on body style and trim, but generally comparable to other vehicles in its class. The manual will detail front and rear track dimensions for alignment purposes.

Ground Clearance:

While not a dedicated off-roader, Subaru models of this era generally offered decent ground clearance for their class, especially AWD variants. Specific measurements would be detailed in the manual.

Weights

Curb Weight:

Likely in the range of 2,400 to 3,000 lbs (1088 to 1360 kg) depending on body style, engine, and drivetrain (AWD adds weight).

Gross Vehicle Weight Rating:

Will be specified in the manual, typically around 3,500 to 4,000 lbs (1588 to 1814 kg).

🛡️ Safety Features

Ratings

Crash Test Data:

Limited comprehensive crash test data available from official agencies (like NHTSA) for this specific model/era due to testing standards at the time. The manual may offer structural integrity information from Subaru's internal testing.

Active Features

Braking System:

Front disc brakes, rear drum brakes were common. Higher trims or specific RX models might have featured front and rear disc brakes. ABS (Anti-lock Braking System) was an available option on some later models.

Passive Features

Restraints:

Seat belts (lap and shoulder belts) were standard. Airbags were not commonly available or standard on most Subaru models of this vintage, but some later RX variants might have been equipped with driver-side airbags.

💡 Technology Features

Infotainment

Audio System:

Basic AM/FM radio with cassette player was standard. Optional premium sound systems with more speakers might have been available. Manual covers basic diagnostics and replacement of audio components.

Driver Assistance

ABS Availability:

Anti-lock Braking System (ABS) was an optional feature on later models within this range, typically limited to higher trim levels or specific markets. The manual will detail ABS system components, diagnosis, and troubleshooting.

Connectivity

Connectivity Features:

Limited by the era. No advanced Bluetooth or USB connectivity. Manual might cover basic wiring for aftermarket accessories.

🔧 Maintenance

Service Intervals

Oil Change Interval:

Typically every 3,000 - 5,000 miles or 3-6 months, depending on driving conditions. Manual will specify based on oil type (mineral vs. synthetic) and usage.

Timing Belt Replacement:

Critical for Boxer engines. Intervals typically 60,000 to 90,000 miles (96,000 to 145,000 km) or 5-7 years. Failure can cause severe engine damage. Manual will provide exact interval and procedure.

Spark Plug Replacement:

Every 30,000 - 60,000 miles, depending on spark plug type (copper vs. platinum). Manual will list correct spark plug part numbers and gap.

Fluid Specifications

Engine Oil Type:

API Service SG or higher. Viscosity grades commonly 10W-30 or 10W-40. Manual will provide detailed specifications and capacities.

Coolant Type:

Ethylene glycol-based antifreeze. Typically a 50/50 mix with distilled water. Manual will specify capacity and potential for Subaru-specific coolants.

Brake Fluid Type:

DOT 3 or DOT 4 brake fluid. Manual will specify the required type and any recommendations for flushing.

Power Steering Fluid:

Specific type, likely ATF Dexron-II or a dedicated power steering fluid. Manual will specify the correct fluid and capacity for the power steering system.

Known Issues

Common Problems:

Head gasket leaks (especially on EA82 engines), radiator leaks, carburetor issues (on older models), worn suspension bushings, starter motor issues, rust (particularly in certain climates), clutch wear. The manual will detail diagnostic procedures for these.

Part Numbers

Oil Filter Part Number Example:

Examples might include Fram PH5100, Purolator L10000, or Wix 51515 (verify exact fitment in manual or parts catalog).
