Additional Notes

  • The Ford Thunderbird DEW carries a cooling system capacity of 11.3 liters across both the 2002-2003 and 2003-2005 3.9 V8 configurations, reflecting a full system fill volume that accounts for the radiator, engine block passages, heater core, and associated hoses.
  • A 240,000 km coolant change interval applies to both the 2002-2003 and 2003-2005 3.9 V8 under normal use conditions, placing the Ford Thunderbird DEW among vehicles specifying an extended-life coolant service schedule rather than a conventional short-cycle replacement interval.
  • The 12-month check interval specified for both configurations means the coolant condition and level are to be inspected annually regardless of mileage accumulation, operating independently from the long-distance change interval.
  • The 2003 model year appears in both row configurations, with the 2002-2003 entry and the 2003-2005 entry sharing identical capacity and interval values of 11.3 liters, a 12-month check, and a 240,000 km change interval.
