Engine Coolant Replacement:
Every 30,000 miles or 2 years (Subaru Super Coolant)
Timing Belt Replacement:
Every 105,000 miles or 7 years (critical for EJ25 engines to prevent catastrophic failure).
Engine Oil Specification:
0W-30, 5W-30, 5W-40 (API SG, SH, SJ, SL or ACEA A1/B1, A3/B3, A3/B4 or ILSAC GF-2, GF-3) - consult manual for exact spec based on climate.
Engine Coolant Type:
Subaru Super Coolant (Blue) or equivalent ethylene glycol-based coolant with anti-corrosion additives. Do not mix with other types.
Brake Fluid Type:
DOT 3 or DOT 4
Head Gaskets:
While less common on the BH chassis compared to earlier generations, head gasket leaks can still occur, particularly with the EJ25 engine. Symptoms include coolant loss, white smoke, or coolant in oil.
Timing Belt Failure:
Critical component. If the timing belt breaks on EJ engines, it will cause severe internal engine damage due to piston-to-valve contact. Regular replacement is paramount.
Catalytic Converter:
Can degrade over time, leading to reduced engine performance and Check Engine Lights.
Cv Axles:
Front and rear CV axles can wear out, leading to clicking noises during turns or acceleration.
