Maintenance:
Scheduled maintenance (oil changes, filter replacements, spark plugs, belts, fluids), lubrication, inspections, adjustments.
Repair:
Engine rebuilds, cylinder head removal/installation, transmission overhaul, brake component replacement, suspension part replacement, electrical component diagnosis and repair, body panel repair.
Troubleshooting:
Diagnostic procedures for common drivability issues, electrical faults, starting problems, cooling system leaks, and other malfunctions.
Specifications:
Torque specifications for critical fasteners, engine clearances, fluid capacities, electrical system voltages, tire pressures, wheel alignment specifications.
Depth:
Comprehensive: Covers routine maintenance to full engine and transmission overhauls, including detailed diagnostic procedures and wiring diagrams.
Engine Codes:
EA81 (1.8L SOHC), EA82 (1.8L SOHC, Turbocharged, and EA82 'SPFI' Single Point Fuel Injection variants)
Horsepower Range:
Approximately 70-73 hp for naturally aspirated EA81, 94-100 hp for naturally aspirated EA82, and 115-130 hp for turbocharged EA82.
Torque Range:
Approximately 95-97 lb-ft for EA81, 102-107 lb-ft for naturally aspirated EA82, and 120-135 lb-ft for turbocharged EA82.
Fuel Delivery:
Carbureted (early EA81), SPFI (Single Point Fuel Injection) for EA82, and Multi-Point Fuel Injection (MPFI) on some later EA82 models and turbocharged variants.
NHTSA Ratings:
No formal NHTSA ratings available for this era. Safety features were typical for the time, focusing on passive restraints and vehicle structure.
Active Safety:
Power-assisted brakes, limited-slip differentials (on some AWD models), and the inherent stability of the AWD system in adverse conditions.
Passive Safety:
Seat belts (lap and shoulder belts), padded interior surfaces, reinforced body structure.
Oil Change Interval:
Typically every 3,000 - 5,000 miles or 3-6 months, depending on driving conditions and oil type used. Refer to specific model year recommendations.
Timing Belt Replacement:
Crucial for EA82 engines (non-interference, but critical for timing). Typically recommended every 60,000 miles or 5 years. Failure can lead to valve damage in some configurations. EA81 engines were often timing chain driven.
Engine Oil Type:
API Service SG or higher recommended. Viscosity: 10W-30 or 10W-40 common, with 5W-30 or 5W-40 in colder climates. Consult manual for exact specifications.
Coolant Type:
Ethylene glycol-based antifreeze. Typically a 50/50 mix with distilled water. Subaru green coolant specific for the era is often recommended.
Transmission Fluid Manual:
GL-4 gear oil, SAE 75W-90 or 80W-90. Capacity varies by model, typically around 2.5-3 liters.
Transmission Fluid Automatic:
Dexron II or equivalent ATF. Capacity around 3-4 liters for a fluid change, more for a complete overhaul.
Differential Fluid:
GL-5 gear oil, SAE 75W-90 or 80W-90. Capacities for front, rear, and center differentials (if applicable) will vary.
Common Wear Items:
Wheel bearings (especially with AWD), CV joints, front struts/shocks, exhaust system components (rust), clutch wear, radiator leaks, heater core issues, and carburetor problems (on carbureted models).
Engine Specific Concerns:
Head gasket leaks on some EA82 variants, particularly those with the SPFI system. Oil leaks from valve covers and oil pan seals. Turbocharged models require diligent maintenance and can be prone to turbocharger failure if not properly maintained.
Heritage:
Subaru, a division of Fuji Heavy Industries, established itself with a focus on reliable, practical, and often innovative vehicles, notably pioneering the widespread use of AWD in passenger cars.
Evolution:
The L-Series (often referred to as the Leone in many markets) was Subaru's second generation of global passenger cars, succeeding the earlier Leone and laying the groundwork for subsequent models like the Impreza and Legacy. It saw evolutionary updates in styling and powertrain options throughout its production run.
Production Period:
The L-Series platform was produced globally from the late 1970s through the mid-1990s, with the specific years covered by this manual (1984-1994) representing the latter half of its lifecycle, incorporating significant updates.
