Additional Notes

  • The Toyota Avalon XX30 (GSX30) 3.5 V6 24V carries a cooling system capacity of 8.3 liters across all model years and both market variants, from 2005 through 2012. A capacity in this range is typical for a transversely mounted V6 with a full-size radiator, thermostat housing, heater core circuit, and overflow reservoir included in the total fill volume.
  • Canadian-market specifications apply a two-tier change interval structure. Under normal use conditions, coolant changes are scheduled at 64,000 km or 48 months for the 2005-2007 GSX30, while the first change only condition extends that interval to 128,000 km or 96 months for the same years. The first change only designation reflects the extended service life of long-life coolant from the factory fill, after which the shorter normal interval governs all subsequent changes.
  • For the Canadian 2008-2012 GSX30, the normal use change interval increased to 80,000 km or 60 months, up from the 64,000 km or 48-month schedule used in 2005-2007. The corresponding first change only interval for 2008-2012 rose to 160,000 km or 120 months, compared to 128,000 km or 96 months in the earlier period.
  • USA-market specifications use a 50,000-mile or 60-month change interval under normal use conditions, applied consistently across all three year groupings: 2005, 2006-2007, and 2008-2012. The first change only interval for USA models is set at 100,000 miles or 120 months throughout the entire 2005-2012 span, with no revision between year groups as seen in the Canadian schedule.
  • The coolant check interval differs between markets. Canadian specifications call for a check every 8,000 km or 6 months, while USA specifications set the check interval at 15,000 miles or 18 months. Both intervals apply equally under normal and first change only conditions within their respective markets.
  • The 2005 model year is listed as a standalone group in both the Canadian and USA specifications, separate from the 2006-2007 grouping, despite sharing identical capacity and interval values with those years. This separation likely reflects a mid-cycle specification review rather than any difference in the actual figures.
