Additional Notes

  • The Hyundai Sonata NF (USA) cooling system capacity for the 2.4-liter engine varies by transmission type, with 6.3 liters specified for automatic transaxle configurations and 6.5 liters for manual transaxle configurations across the full 2006-2010 model year span.
  • The 3.3-liter engine carries a single cooling system capacity of 8.2 liters regardless of transmission type, a notably larger fill volume than the 2.4-liter engine, reflecting the greater thermal mass and larger block displacement of the V6 configuration.
  • For the 2.4-liter engine in 2006-2008, the normal-use coolant change interval is set at 30,000 miles or 24 months, whichever comes first, while the initial service interval extends significantly to 60,000 miles or 60 months.
  • The 2009-2010 2.4-liter engine sees a reduction in the normal-use coolant change interval from 30,000 miles to 25,000 miles, while the 24-month time limit and the initial service interval of 60,000 miles or 60 months remain unchanged from the earlier 2006-2008 specification.
  • The 3.3-liter engine in 2006-2008 shares the same normal-use interval structure as the 2.4-liter engine of the same years, at 30,000 miles or 24 months, with an initial service interval of 60,000 miles or 60 months.
  • For the 3.3-liter engine in 2009-2010, the normal-use interval is reduced to 25,000 miles or 24 months, mirroring the same mileage adjustment applied to the 2.4-liter engine for those model years, while the initial service interval remains at 60,000 miles or 60 months.
  • The initial service interval of 60,000 miles or 60 months applies uniformly across all engine variants and all model years in the 2006-2010 range, representing a significantly extended first-change schedule compared to the recurring normal-use intervals.
