Hyundai Accent, HC (USA)

Coolant capacity & service interval

Hyundai Accent, HC (USA) uses coolant with a capacity range of 5,3 to 6,6 liters. Service intervals consist of 30000 miles or 24 months and 120000 miles or 120 months. The data covers 4 configurations.

The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

Additional Notes

  • The Hyundai Accent HC (USA) cooling system specifications cover two distinct engine variants: the 1.6 GDI, applicable to 2018-2019 model years, and the 1.6 MPI, applicable to 2019-2022 model years.
  • The 1.6 GDI cooling system holds 5.3 liters of coolant, while the 1.6 MPI holds either 6.6 liters with an IVT transmission or 6.4 liters with a manual transaxle, reflecting a meaningful capacity difference between the two engine families.
  • On the 1.6 MPI, the transmission type directly influences coolant capacity, with the IVT configuration requiring 0.2 liters more than the manual transaxle configuration.
  • Under normal use conditions, both the 1.6 GDI and 1.6 MPI share the same coolant change interval of 30,000 miles or 24 months, whichever comes first.
  • A separate first-change-only interval applies to both engine variants, specifying a single coolant replacement at 120,000 miles or 120 months. This extended interval is a one-time service event rather than a recurring schedule, distinguishing it from the normal use interval.
  • The first-change-only interval of 120,000 miles or 120 months on the 1.6 GDI applies to the same 5.3-liter cooling system capacity as the normal service interval, meaning the fill volume does not differ between the two service conditions.
  • The same relationship holds for the 1.6 MPI: the 6.6-liter and 6.4-liter capacities listed under normal use conditions are identical to those listed under the first-change-only condition, confirming that capacity figures are independent of service interval type.
