Kia Soul, SK3 (USA / CAN)

Coolant capacity & service interval

Kia Soul, SK3 (USA / CAN) models require coolant with a capacity range of 5,5 to 6,9 liters. Service intervals include 24000 miles/24 months, 30000 miles/24 months, and 120000 miles/120 months. The data covers 6 configurations.

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

Additional Notes

  • The Kia Soul SK3 1.6 T-GDI carries a cooling system capacity of 6.9 liters, which is notably larger than the 5.5-liter capacity of the 2.0 MPI, reflecting the greater thermal management demands of a turbocharged engine compared to a naturally aspirated one.
  • Both the 1.6 T-GDI and the 2.0 MPI (2019-2022) share a normal-use coolant change interval of 30,000 miles or 24 months, whichever comes first.
  • Under a first-change-only condition, both the 1.6 T-GDI and the 2.0 MPI (2019-2022) specify an extended interval of 120,000 miles or 120 months, indicating the factory-fill coolant is formulated for a significantly longer initial service life before the standard recurring schedule takes over.
  • The 2.0 MPI entry starting from 2022 carries a reduced normal-use interval of 24,000 miles or 24 months, compared to the 30,000-mile interval listed for the 2.0 MPI in the 2019-2022 range, representing a shorter recurring service cycle for the same engine displacement.
  • Despite the interval difference between the two 2.0 MPI entries, the cooling system capacity remains consistent at 5.5 liters across both, meaning the volume of coolant required per service fill does not change between the two interval specifications.
  • The first-change-only interval for the 2022 2.0 MPI remains at 120,000 miles or 120 months, identical to the earlier 2019-2022 2.0 MPI entry, even though the normal recurring interval was shortened.
