Additional Notes

  • The Borgward Isabella's cooling system holds 7 liters across all five variants covered in the 1957-1962 range, including the Combi, Coupé/Cabrio, Standard, TS, and TS de Luxe.
  • A 7-liter coolant capacity is a moderately sized fill for a 1500cc engine of that era, reflecting the volume needed to circulate fluid through the engine block, cylinder head, and radiator.
  • The 12-month change interval applies under normal use conditions across every listed variant, meaning annual coolant replacement was the standard maintenance cycle regardless of body style or trim level.
  • No variation in capacity or service interval exists between the entry-level Standard and the higher-specification TS de Luxe, indicating the shared 1500cc engine architecture drove a uniform cooling system specification.
  • The Coupé and Cabrio body styles share the same 7-liter capacity and 12-month interval as the Combi wagon and sedan-based variants, confirming the cooling system was not altered to accommodate different body configurations.
