Depth:
Comprehensive, covering everything from routine maintenance to complete engine and transmission overhauls. Includes detailed diagnostic information and torque specifications.
Oil Change Interval:
Typically every 10,000-15,000 km (6,000-9,000 miles) or 6-12 months, depending on driving conditions and oil used.
Timing Belt Replacement:
Crucial service. For EJ20/EJ22/EJ25 engines, typically recommended every 90,000-105,000 km (56,000-65,000 miles) or 7 years, whichever comes first.
Engine Oil:
API SG/SH/SJ or higher, viscosity typically 5W-30 or 10W-30 (refer to manual for specific grade and capacity).
Transmission Fluid Auto:
Subaru Genuine ATF or equivalent (e.g., Dexron III/Mercon). Capacity approximately 4-5 liters for a fluid change.
Transmission Fluid Manual:
API GL-5, SAE 75W-90 gear oil. Capacity typically around 2.5-3.0 liters.
Coolant:
Subaru Super Coolant or a quality ethylene glycol-based coolant with corrosion inhibitors. Capacity approximately 7-8 liters.
Brake Fluid:
DOT 3 or DOT 4 brake fluid.
Head Gaskets:
While less common on the EJ25s compared to earlier Subaru engines, head gasket leaks can still occur, particularly with age and heat cycles.
Automatic Transmission:
Some automatic transmissions can develop issues with solenoids or torque converters, particularly with high mileage and irregular fluid changes.
Suspension Components:
Wear in bushings, ball joints, and tie rod ends can lead to noise and steering play over time.
Oxygen Sensors:
Oxygen sensors can degrade over time, affecting fuel economy and emissions.
