Additional Notes
- The BMW 7 Series E38 (USA) 740i carries a coolant system capacity of 12.5 liters across both the 1994-1996 and 1996-2001 model year spans, indicating a full cooling system fill rather than a partial or component-level service volume.
- A 12.5-liter capacity is consistent with a large-displacement inline-six or V8 engine cooling circuit, reflecting the volume needed to service the engine block, cylinder head passages, radiator, heater core, and associated hoses in a single fill.
- Both the 1994-1996 and 1996-2001 740i configurations share the identical 12.5-liter figure, meaning no capacity adjustment was introduced between the two production spans for the cooling system.
- The use condition listed for both 740i entries is normal, meaning the 12.5-liter specification applies to standard operating environments rather than a severe-duty or first-change-only service scenario.
