Additional Notes

  • The BMW 7 Series E65 (USA) 745i carries a coolant capacity of 14.1 liters, which represents a full cooling system fill volume rather than a partial or overflow reservoir quantity.
  • The 745i cooling system capacity of 14.1 liters reflects the demands of a large-displacement engine bay, where extended coolant passages through the block, heads, and auxiliary circuits contribute to a higher total fill volume.
  • Under normal use conditions, the 745i cooling system specifies a change interval of 48 months, meaning the coolant is rated for a four-year service life before replacement is due.
