Subaru Forester, SK (EU)

Coolant capacity & service interval

Subaru Forester, SK (EU) coolant capacity ranges from 7,7 to 8 liters. Service intervals include checks at 30000 km or 24 months, and changes at 120000 km or 72 months and 220000 km or 132 months. The data covers 6 configurations.

Additional Notes

  • The Subaru Forester SK (EU) cooling system holds 8 liters in both the 2.0i and 2.0i e-Boxer variants, while the 2.5i carries a slightly lower capacity range of 7.7–7.9 liters.
  • The 7.7–7.9 liter range on the 2.5i reflects a service fill tolerance rather than a fixed volume, which is common when coolant displacement varies slightly depending on bleeding completeness or residual fluid in the system.
  • Across all three engine variants, the coolant check interval is set at 30,000 km or 24 months, whichever comes first, and applies under normal use conditions.
  • Under normal use, the coolant change interval for all variants is 120,000 km or 72 months, equivalent to a six-year or roughly 120,000 km service cycle.
  • An initial service designation carries a significantly extended change interval of 220,000 km or 132 months, which represents 11 years compared to the six-year normal cycle, indicating the factory-fill coolant is formulated for a longer first-drain life.
  • The initial service change interval of 220,000 km applies equally to the 2.0i, 2.0i e-Boxer, and 2.5i, with no variation in the extended drain period across engine types.
  • Despite the difference in total capacity between the 2.0i and 2.5i engines, the check and change intervals are identical across both normal and initial service conditions for all listed variants.
  • The 2.0i e-Boxer shares the same 8-liter cooling system capacity and identical service intervals as the standard 2.0i, with specifications introduced from 2019 onward.
