Additional Notes
- The Subaru Forester SJ (EU) 2.0 XT carries the largest cooling system capacity across all listed variants at 9 liters, reflecting the greater thermal demands of a turbocharged engine compared to the naturally aspirated petrol and diesel alternatives in the same generation.
- The 2.0D diesel variant specifies a capacity range of 8.2–8.3 liters, a narrow band that accounts for minor variation in system fill depending on configuration, and sits between the 2.0 XT and the naturally aspirated petrol engines in total volume.
- Both the 2.0i and 2.5i petrol variants share a capacity range of 7.7–8.3 liters, with the 2.0i ranging 7.8–8.3 liters and the 2.5i ranging 7.7–7.9 liters. The overlap in these figures reflects similar engine architecture across the horizontally opposed petrol family.
- All variants across the 2013-2018 range share a uniform coolant check interval of every 30,000 km or 24 months, whichever comes first, regardless of engine type or displacement.
- Under normal use conditions, all listed variants specify a coolant change interval of 120,000 km or 72 months. At a 72-month cycle, a full coolant replacement falls due approximately every six years under standard operating conditions.
- The initial service condition extends the coolant change interval significantly, to 220,000 km or 132 months. The 132-month figure represents an 11-year interval, applicable only to the first factory-filled coolant charge rather than subsequent refills.
- The extended initial service interval of 220,000 km or 132 months applies uniformly across all engine variants, including the 2.0 XT, 2.0D, 2.0i, and 2.5i, indicating the factory-fill coolant specification is consistent across the model range.
- The 2.0i and 2.5i variants each appear under two separate year bands, 2013-2014 and 2015-2018, yet the capacity figures and service intervals are identical across both periods, indicating no cooling system specification change occurred at the 2015 model year revision for those engines.
