Additional Notes

  • The Subaru WRX VB 2.4T cooling system holds between 8.5 and 8.7 liters, a range that reflects minor variation in fill level depending on how completely air is purged from the system during service.
  • Under normal use conditions, the coolant change interval is set at 75,000 miles or 72 months, whichever comes first.
  • A first change only condition carries a significantly extended change interval of 137,500 miles or 132 months, which applies to the original factory fill rather than subsequent service fills.
  • Regardless of use condition, the check interval remains the same at 30,000 miles or 30 months, meaning inspection frequency does not vary between normal and first change only schedules.
  • The gap between the normal change interval of 72 months and the first change only interval of 132 months represents a difference of 60 months, reflecting the longer service life typically associated with factory-installed long-life coolant formulations.
