Additional Notes

  • The Kia Carnival KA4 3.5 GDi cooling system holds between 8.6 and 9.4 liters, a range that reflects variation across individual units rather than a single fixed fill volume.
  • The 1.6 T-GDI Hybrid cooling system carries a notably larger capacity of 11.4 liters compared to the 3.5 GDi, a difference consistent with the additional thermal management demands of a hybrid powertrain.
  • On the 1.6 T-GDI Hybrid, the inverter cooling circuit is a separate loop with a capacity of 1.7 liters, serviced on its own interval of 32,000 miles or 36 months under normal use conditions.
  • The main cooling system on the 1.6 T-GDI Hybrid follows a normal-use interval of 24,000 miles or 24 months, which is the same interval applied to the 3.5 GDi cooling system under normal use.
  • For the 3.5 GDi, a first-change-only interval of 120,000 miles or 120 months is specified, meaning the extended interval applies exclusively to the initial coolant replacement rather than to subsequent service cycles.
  • The 1.6 T-GDI Hybrid uses an initial service designation rather than a first-change-only label for the 120,000-mile or 120-month interval, a distinction that may reflect a difference in how the hybrid system's coolant life is categorized.
