Additional Notes

  • The Subaru WRX (EU) cooling system capacity for the 2.5T WRX spans 7.7 to 8.1 liters, while the 2.5T WRX STI carries a slightly wider range of 7.6 to 8.3 liters across the 2011-2014 model years.
  • Both the 2.5T WRX and 2.5T WRX STI share the same coolant check interval of every 30,000 km or 24 months, regardless of use condition.
  • Under normal use, the coolant change interval for both the 2.5T WRX and 2.5T WRX STI is set at 120,000 km or 72 months.
  • The initial service use condition extends the coolant change interval significantly, reaching 220,000 km or 132 months for both the 2.5T WRX and 2.5T WRX STI, compared to the 120,000 km normal use interval.
  • The 132-month figure tied to the initial service change interval represents an 11-year span, which reflects the extended protection period associated with factory-fill coolant formulations before the first scheduled drain and refill.
  • The wider capacity range on the 2.5T WRX STI, 7.6 to 8.3 liters versus 7.7 to 8.1 liters on the standard 2.5T WRX, suggests a broader variation in fill volume that may correspond to differences in cooling circuit layout between the two configurations.
