iX3 (2020-2021)
  • Use: Normal
  • Capacity 19,6 liter

Additional Notes

  • The BMW iX3 G08 (EU) cooling system holds 19.6 liters of coolant, a figure that reflects the total system capacity rather than a partial service fill, meaning the full volume accounts for the radiator, reservoir, and all associated passages throughout the electric drivetrain's thermal management circuit.
  • The 19.6-liter capacity listed for the iX3 (2020-2021) applies under normal use conditions, which in coolant service contexts generally refers to standard operating environments as opposed to extended-drain or severe-duty scenarios.
  • The iX3 M Sport variant, with a starting year of 2021, shares the same 19.6-liter cooling system capacity under normal use conditions as the standard iX3, indicating no differentiation in thermal system volume between the two configurations despite the M Sport designation.
