Additional Notes

  • The Kia Cadenza YG 3.3 GDI cooling system holds 8.5 liters across the 2016-2018 model years, while the 2019-2021 model years carry a slightly larger capacity of 8.6 liters.
  • The 0.1-liter increase in cooling system capacity between the earlier and later production spans is a small but distinct specification difference tied to model year, not engine displacement, as all configurations share the same 3.3 GDI engine.
  • Under normal use conditions, the cooling system interval is set at 30,000 miles or 24 months across all model years covered in the specifications, applying uniformly regardless of the minor capacity difference between generations.
  • A separate first-change-only interval of 120,000 miles or 120 months is specified for all model years, meaning the initial factory-fill coolant is rated for a significantly longer service life before the first scheduled replacement.
  • The 120-month first-change interval translates to a 10-year service life for the original coolant charge, which reflects the extended protection characteristics typically associated with long-life coolant formulations used at the factory.
  • Following the first-change-only service, the normal use interval of 30,000 miles or 24 months applies, representing a substantially shorter cycle than the initial fill period.
  • The 8.5-liter capacity recorded for the 2016-2018 3.3 GDI configurations is consistent across both the normal and first-change-only rows, confirming a single fill volume regardless of service interval type.
  • The same consistency holds for the 2019-2021 configurations, where the 8.6-liter capacity appears in both the normal and first-change-only rows without variation.
