Additional Notes

  • The Subaru Trezia (EU) 1.3i carries a cooling system capacity of 4.8 liters when paired with a CVT and 4.6 liters when paired with a manual transmission, a difference that reflects the additional coolant volume routed through or around the CVT unit in the drivetrain layout.
  • Across both the 2011-2012 and 2013-2015 production spans of the 1.3i, the capacity figures remain identical at 4.8 liters (CVT) and 4.6 liters (manual), indicating no change in cooling system volume between the two model year groups.
  • The 1.5i engine carries the largest cooling system capacity in the Trezia lineup at 5 liters, a single fixed value that applies regardless of transmission type, unlike the transmission-dependent split seen in the 1.3i.
  • The 1.4 D diesel engine has a capacity range of 4.3 to 4.6 liters rather than a single fixed value, which typically reflects minor variation in fill level depending on assembly tolerances or bleed procedure outcomes during a service fill.
  • All three engine variants share the same normal-use coolant change interval of 90,000 km, applying uniformly across the 1.3i, 1.4 D, and 1.5i configurations throughout the 2011-2015 model years.
  • A first change only interval of 150,000 km is specified across all engine variants, meaning the initial factory-fill coolant is rated for a longer service life before the standard 90,000 km recurring interval takes effect on subsequent changes.
  • The 150,000 km first change only interval for the 1.3i applies equally to both the CVT and manual transmission variants, as the extended initial interval is tied to the coolant formulation rather than the drivetrain configuration.
