Additional Notes

  • The BMW X4 G02 / F98 coolant system is split into two separate circuits: a high temperature cooling circuit and a low temperature cooling circuit, each carrying a distinct fluid capacity.
  • On the X4 xDrive M40i, the high temperature circuit holds 14.8 liters, while the low temperature circuit holds 4.1 liters, and both figures remain consistent across units produced up to 30-06-2018 and those produced as of 01-07-2018.
  • The X4 xDrive30i carries a smaller high temperature circuit capacity of 12.6 liters compared to the xDrive M40i, reflecting the difference in engine displacement and thermal output between the two variants.
  • The low temperature circuit on the xDrive30i is rated at 4 liters for 2018-2019 production, a figure that is slightly lower than the 4.1 liters specified for the xDrive M40i across the same period.
  • For the xDrive30i starting from 2019, the high temperature circuit capacity is listed as a range of 11.2-12.6 liters rather than a fixed value, indicating a tolerance band rather than a single fill target.
  • The low temperature circuit on the xDrive30i starting from 2019 is similarly expressed as a range of 4.0-4.2 liters, consistent with the variable capacity notation applied to the high temperature circuit for the same configuration.
  • All coolant capacity figures across the X4 G02 / F98 specifications are associated with normal use conditions, meaning no separate severe-use interval or capacity distinction is listed for the cooling system.
