Vehicle Segment:
Mid-size sedan and wagon, known for its All-Wheel Drive (AWD) system.
Competitors:
Toyota Camry, Honda Accord, Nissan Altima, Mazda 626.
AWD Standard:
Subaru's symmetrical All-Wheel Drive was a significant differentiator.
Engine Layout:
Horizontally opposed ('boxer') engines, contributing to a lower center of gravity.
Engine:
Detailed diagnostics, overhaul, lubrication, cooling, fuel delivery, ignition, emissions control, and timing systems.
Transmission:
Service and repair for both manual and automatic transmissions, including fluid changes, clutch service, and internal component diagnostics.
Drivetrain:
Coverage of front and rear differentials, AWD system components, driveshafts, axles, and CV joints.
Suspension:
Front and rear suspension systems, including shock absorbers, struts, control arms, ball joints, bushings, and alignment procedures.
Brakes:
Service and repair for hydraulic brake systems, including master cylinder, brake lines, calipers, pads, rotors, and ABS components (if applicable).
Steering:
Power steering system service, including pump, rack and pinion, hoses, and fluid maintenance.
Electrical:
Extensive coverage of the electrical system, including battery, charging system, starter, lighting, fuses, relays, wiring diagrams, and ECU diagnostics.
Body:
Body panel repair, interior trim removal and installation, glass replacement, and chassis component diagnostics.
HVAC:
Air conditioning system servicing, heater core replacement, blower motor, and climate control unit diagnostics.
Climate Control:
Details on heater, ventilation, and air conditioning (HVAC) system operation, servicing, and repair.
Maintenance:
Scheduled maintenance tasks, fluid changes, filter replacements, tune-ups, and general inspections.
Troubleshooting:
Diagnostic flowcharts and symptom-based troubleshooting for common and complex issues.
Repair:
Step-by-step repair instructions for all major vehicle components and systems, including complete overhauls.
Specifications:
Torque specifications, clearances, fluid capacities, and electrical values for accurate repairs.
Wiring Diagrams:
Detailed electrical wiring diagrams for all vehicle circuits.
Diagnostic Tools:
Information on using basic diagnostic tools and interpreting fault codes (OBD-I systems were prevalent, with some transition to OBD-II).
Depth Of Coverage:
Expert-level detail suitable for professional mechanics and advanced DIY enthusiasts, covering everything from basic maintenance to complete engine and transmission rebuilds.
Oil Change Interval:
Every 3,750 miles or 3 months (typical, check manual for exact recommendation).
Timing Belt Replacement:
Every 60,000 - 90,000 miles (critical for EJ engines, consult manual).
Coolant Flush Interval:
Every 24,000 miles or 24 months (typical).
Engine Oil Type:
API SG or SH, SAE 5W-30 (preferred in most climates) or 10W-30. Consult manual for specific recommendations.
Engine Oil Capacity:
4.5 US quarts (4.3 L) with filter (approx. for 2.2L).
Transmission Fluid Manual:
API GL-5, SAE 75W-90 Gear Oil.
Transmission Fluid Automatic:
Subaru ATF-HP or equivalent Dexron-III/Mercon type fluid.
Coolant:
Subaru Super Coolant or equivalent ethylene glycol based coolant (50/50 mix).
Head Gaskets:
While not as prevalent as in later EJ25 DOHC engines, head gasket leaks can occur, especially with overheating. The EJ22 SOHC is generally more robust.
Oil Leaks:
Valve cover gaskets and oil pan gaskets can degrade over time, leading to leaks.
Suspension Wear:
Bushings, ball joints, and struts can wear out, affecting ride quality and alignment.
Exhaust Manifold Cracks:
Certain EJ engines were prone to exhaust manifold cracks due to heat cycles.
