Additional Notes

  • The Kia Rio 1.6 cooling system capacity differs by transaxle type for 2017-2020 configurations, with the automatic transaxle requiring 5.5 liters and the manual transaxle requiring 5.4 liters.
  • For the 2020-2023 Rio 1.6, a single cooling system capacity of 6.6 liters applies regardless of transaxle type, which is a notable increase over the 5.4-5.5 liter range specified for earlier model years.
  • Across all covered model years, the normal-use coolant change interval is set at 30,000 miles or 24 months, whichever comes first.
  • A first change only interval of 120,000 miles or 120 months is specified for all covered configurations, reflecting the extended service life of the factory-fill coolant before the standard recurring interval takes over.
  • The 120-month first change only interval equals 10 years of calendar-based service life, indicating the initial factory coolant fill is formulated for long-term protection before the 24-month recurring cycle begins.
  • The 2019 Rio 1.6 appears under two separate configuration entries, one covering 2019 alone and another covering 2019-2020, both sharing the same 5.5 liter automatic and 5.4 liter manual capacities with identical change intervals.
