Additional Notes

  • The cooling system capacity across all four configurations is 6.6 liters, a figure consistent with a fully drained and refilled service rather than a partial top-off, meaning the value reflects total system volume.
  • The Hyundai Elantra HD 2.0 for 2007-2008 carries a normal-use coolant change interval of 25,000 miles or 24 months, whichever comes first.
  • For the 2009-2010 2.0 engine, the normal-use interval increases to 30,000 miles while retaining the same 24-month time limit, representing a longer mileage threshold compared to the 2007-2008 specification.
  • Both the 2007-2008 and 2009-2010 configurations share an identical initial service interval of 60,000 miles or 60 months, applied specifically under the initial service use condition rather than the recurring normal schedule.
  • The gap between the normal-use interval and the initial service interval is substantial in both model year groups, with the initial service threshold set at more than double the mileage of the normal-use figure, reflecting the extended protection period of a factory-fill coolant formulation.
