BMW 2 series, G42 / G87 (USA)

Additional Notes

• The BMW 2 Series G42/G87 (USA) cooling system is split into two separate circuits across all listed configurations: a high temperature cooling circuit serving the engine and a low temperature cooling circuit typically associated with charge air cooling or auxiliary thermal management.
• The 230i carries 9.8 liters in the high temperature cooling circuit and 4.2 liters in the low temperature cooling circuit, giving a combined system capacity of 14.0 liters.
• The 230i xDrive shares identical capacities with the rear-wheel-drive 230i, at 9.8 liters and 4.2 liters for the high and low temperature circuits respectively, despite the addition of all-wheel-drive hardware.
• The M240i and M240i xDrive both carry 10.5 liters in the high temperature cooling circuit and 4.5 liters in the low temperature cooling circuit, reflecting the greater thermal load of the inline-six engine compared to the four-cylinder 230i variants.
• The M2 carries the largest high temperature cooling circuit capacity among all listed configurations at 11.0 liters, and also the largest low temperature circuit at 6.6 liters, for a combined total of 17.6 liters.
• The M2 low temperature circuit capacity of 6.6 liters is notably larger than the 4.2-liter and 4.5-liter figures seen in the 230i and M240i variants, indicating a substantially more demanding auxiliary cooling requirement consistent with a high-performance application.
• All five configurations share the same use condition designation of normal, meaning the listed capacities apply to standard operating conditions without a separate severe-use or first-fill distinction in the specifications.
