Additional Notes

  • The cooling system capacity of 15 liters remains constant across every Aston Martin DB9 variant listed from 2003 through 2016, including the DB9 GT introduced in 2015. This figure represents the total coolant volume held within the radiator, hoses, and engine block during a full system fill, rather than a smaller top-off amount.
  • A check interval of 16,000 km or 12 months applies uniformly to all listed configurations under normal use conditions. This interval typically involves inspecting coolant level and condition rather than replacing the fluid outright.
  • The change interval, set at 160,000 km or 60 months, is ten times longer in distance than the check interval and five times longer in duration. Such a wide gap between inspection and replacement reflects the extended service life of modern coolant formulations under normal operating conditions.
  • No variation appears in coolant capacity or interval figures across the six standard DB9 model year groupings spanning 2003 to 2016, despite changes in production year ranges.
  • The DB9 GT, listed separately for 2015-2016, shares identical coolant specifications with the standard DB9 of the same period, indicating no divergence in cooling system design or maintenance scheduling between these two trims.
  • Interval values are expressed as dual thresholds, distance traveled or time elapsed, whichever occurs first. This dual-metric approach accounts for vehicles that accumulate low mileage but still experience fluid degradation over calendar time.
