Additional Notes

  • The Subaru Legacy / Outback BD/BG/BK (EU) coolant system capacity across the 2.0, 2.0 4WD, and 2.5 4WD variants is uniformly 6 liters, indicating a consistent cooling system volume despite differences in drivetrain configuration.
  • The 2.2-liter variant in two-wheel drive configuration carries a slightly larger cooling system capacity of 6.4 liters, the highest figure across all listed engine variants in the 1994-1998 range.
  • The 2.2 4WD variant holds a notably lower capacity of 5.8 liters compared to the two-wheel drive 2.2, a difference of 0.6 liters that reflects how drivetrain packaging can affect cooling system volume within the same engine displacement.
  • All five configurations share an identical service interval of 50,000 km or 24 months under normal use conditions, whichever comes first, meaning time elapsed is as much a factor as distance traveled when determining a coolant change.
  • The 2.5 4WD variant covers the narrower model year span of 1996-1999, while the 2.0 and 2.2 variants begin from 1994, reflecting a later introduction of the 2.5-liter engine into the EU-market lineup.
  • The 2.2-liter engine variants are listed through 1998 only, whereas the 2.0 and 2.5 4WD variants extend to 1999, meaning the final model year of the range does not include 2.2-liter coverage in these specifications.
