Crucial interval, typically every 100,000 km (60,000 miles) or 5 years. Failure can cause catastrophic engine damage due to interference design.
Fluid Specifications
Engine Oil:
API SG or SH, SAE 10W-30 or 10W-40 (check manual for specific viscosity based on temperature range and Subaru's approval).
Coolant:
Subaru Super Coolant (blue) or equivalent ethylene glycol-based coolant with corrosion inhibitors. Mix 50/50 with distilled water.
Brake Fluid:
DOT 3 or DOT 4, depending on ABS presence. Regular replacement recommended due to hygroscopic nature.
Known Issues
Head Gaskets:
While less prone than later EJ engines, head gasket leaks can still occur, especially with high mileage or overheating. The EJ22 is generally considered more robust in this regard.
Fuel Injectors:
Clogging of fuel injectors can lead to rough idling and performance issues.
O2 Sensors:
Oxygen sensors can degrade over time, affecting fuel mixture and emissions.
Cv Boots:
Cracked or torn CV boots allow dirt and moisture in, leading to premature CV joint failure, particularly on AWD models.
Wheel Bearings:
Front wheel bearings can wear out, causing humming or grinding noises.
