Kia EV3, SV1 (EU)

Coolant capacity & service interval

Kia EV3 and SV1 (EU) models require 17,3 liters of coolant. Service intervals include 30000 km or 24 months and 180000 km or 120 months. The data covers 4 configurations.

Additional Notes

  • The Kia EV3 cooling system holds 17.3 liters across both the 58 kWh and 81 kWh variants, a capacity consistent with the thermal management demands of electric drivetrains, which rely on liquid cooling for the battery pack, inverter, and motor rather than an internal combustion engine.
  • Under normal use conditions, the coolant change interval for both EV3 configurations is set at 30,000 km or 24 months, whichever comes first, reflecting a relatively frequent renewal cycle tied to maintaining coolant chemistry in high-voltage thermal systems.
  • A separate first-change-only interval of 180,000 km or 120 months applies to both the 58 kWh and 81 kWh variants, meaning the initial factory-fill coolant is specified for a significantly extended service life before the standard recurring interval takes over.
  • The gap between the first-change-only interval of 180,000 km and the subsequent normal interval of 30,000 km reflects a common practice in which the original factory coolant contains additives formulated for a longer initial service period than subsequent refills.
  • The identical 17.3-liter capacity across both the 58 kWh and 81 kWh battery configurations suggests the two variants share the same cooling system architecture despite differing in energy storage capacity.
