Additional Notes

  • The Subaru Forester SG (EU) 2.0 with a manual transmission holds 6.6 liters of coolant, while the automatic transmission variant requires a slightly reduced fill of 6.5 liters, reflecting the different thermal load distribution between the two drivetrain configurations.
  • The 2.0 T engine in the 2002-2005 Forester carries a notably higher cooling system capacity of 7.4 liters compared to the naturally aspirated 2.0, which is consistent with the additional heat rejection demands of a turbocharged engine.
  • On the 2002-2005 Forester 2.0 T, fitting an oil cooler reduces the coolant capacity from 7.4 liters to 7.3 liters, as the oil cooler circuit displaces a small portion of the total coolant volume within the system.
  • The 2002-2005 Forester 2.0 and 2.0 T both carry a coolant check interval of 24 months or 30,000 km under normal use conditions, whichever comes first.
  • The 2005-2008 Forester 2.5 T holds 7.3 liters of coolant, a figure identical to the 2002-2005 2.0 T with oil cooler, despite the larger displacement of the 2.5-liter engine.
  • The 2005-2008 Forester 2.5 naturally aspirated variant has a cooling system capacity of 6.8 liters, placing it between the 2.0 naturally aspirated and the turbocharged engine figures within the same generation.
  • The 2005-2008 Forester 2.0 is listed with a single capacity value of 6.5 liters, which aligns with the automatic transmission figure from the earlier 2002-2005 2.0 specification rather than the manual transmission value of 6.6 liters.
