Additional Notes

  • The Ford Cortina Mk II (EU) rear differential capacity is 1.13 liters across all listed variants, spanning the 1300, 1500, 1600, 1600 GT, 1600E, and Cortina Lotus configurations from 1966-1970.
  • A rear differential fill capacity of 1.13 liters is consistent with the compact, live rear axle units commonly fitted to small European saloons of the late 1960s, where housing volume was kept minimal to reduce unsprung weight.
  • The 1.13-liter figure represents a service fill capacity, meaning the quantity of fluid required when refilling a drained but otherwise intact differential unit during routine maintenance, rather than a total system volume that would include residual fluid from an overhaul.
  • The Cortina 1500 variant carries this specification only for 1966-1967, a shorter production window than the 1300, which shares the same 1.13-liter capacity across the full 1966-1970 span.
  • The 1600, 1600 GT, and 1600E variants all entered the specification range from 1967, aligning with the mid-cycle introduction of the larger-displacement engine options, yet none required a different differential fluid capacity from the earlier 1300 or 1500 models.
  • The Cortina Lotus, a higher-performance variant covering 1966-1970, shares the identical 1.13-liter rear differential capacity with all other listed configurations despite its distinct performance character.
  • All six configurations carry a normal use condition designation, meaning the listed 1.13-liter capacity applies to standard operating conditions rather than a modified interval or quantity associated with severe or high-stress use.
