Additional Notes

  • The Hyundai Equus VI (USA) 4.6 MPI V8 from 2011 carries a cooling system capacity of 13.6 liters, which represents the total volume of the cooling circuit including the engine block, cylinder head passages, radiator, and reservoir.
  • The 5.0 GDI V8, covering model years 2012-2016, holds a cooling system capacity of 12.1 liters, which is 1.5 liters less than the 4.6 MPI V8 despite being a larger displacement engine.
  • Under normal use conditions, both the 4.6 MPI V8 and the 5.0 GDI V8 share an identical coolant change interval of 30,000 miles or 24 months, whichever comes first.
  • A separate first-change-only interval of 120,000 miles or 120 months applies to all engine configurations across 2011-2016, meaning the factory-fill coolant is specified to remain in service far longer before the initial drain and refill than subsequent normal-interval changes.
  • The 120-month first-change-only interval spans a full decade, reflecting the extended service life typically associated with long-life coolant formulations used as original factory fills.
  • The 5.0 GDI V8 specifications remain consistent across two separate year groupings, 2012-2013 and 2014-2016, with no change in either the 12.1-liter capacity or the service intervals between those periods.
