Additional Notes
- Across the BMW 1 Series E82 (USA), the cooling system capacity varies by transmission type on all non-M configurations, with automatic transmission fitments holding 8.4 liters and manual transmission/transaxle fitments holding 8.2 liters.
- The 0.2-liter difference between automatic and manual transmission variants reflects the additional coolant volume routed through an automatic transmission oil cooler, which is integrated into the cooling circuit on automatic-equipped models.
- The 128i is available with two engine variants in the E82 body: the N51 covering 2008-2013 and the N52 covering 2007-2013. Both share identical cooling system capacities of 8.4 liters with automatic transmission and 8.2 liters with manual transmission.
- The 135i also spans two engine generations within the E82 platform: the N54 from 2007-2010 and the N55 from 2010-2013. Despite the engine change, cooling system capacities remain at 8.4 liters with automatic and 8.2 liters with manual transmission.
- The M Coupé, covering 2011-2013, carries a single cooling system capacity of 8.2 liters with no transmission-based variation listed, which aligns with the manual transmission figure seen across other E82 configurations.
