Additional Notes

  • The Subaru Legacy / Outback BE, BH, BT (EU) cooling system capacity across the 1998-2004 range sits at either 6.0 liters or 5.9 liters, depending on engine displacement.
  • Both the 2.0 and 2.0 4WD variants share an identical 6.0-liter cooling system capacity, indicating no difference in coolant volume between the two-wheel-drive and four-wheel-drive versions of the same engine.
  • The 2.5 4WD carries a slightly lower cooling system capacity of 5.9 liters, a 0.1-liter reduction compared to the 2.0-liter configurations.
  • All three configurations list a coolant change interval of 50,000 km or 24 months, whichever comes first, under normal use conditions.
  • The 24-month time-based interval runs alongside the 50,000 km distance limit, meaning calendar time alone can trigger a coolant change even when mileage accumulation is low.
  • All capacity figures listed represent cooling system fills rather than overhaul-level measurements, reflecting the total volume of coolant the system holds during a standard service refill.
