Additional Notes

  • The Renault 14 (EU) cooling system holds a capacity of 6 liters across all listed trim variants, which is a typical figure for a compact front-wheel-drive car of the late 1970s and early 1980s and reflects a full system fill rather than a partial top-up volume.
  • The 14L, R121 covering 1976-1978 shares the same 6-liter capacity and 45,000 km / 36-month change interval as the later trims introduced from 1979 onward, indicating no revision to coolant system sizing between the early and mid production periods.
  • The 14GTL, 14LS, 14TL, and 14TS variants all carry identical coolant specifications, meaning the cooling system design was consistent across the trim hierarchy despite differences in equipment level and engine tuning.
  • A 36-month change interval is specified alongside the 45,000 km mileage threshold under normal use conditions, meaning whichever limit is reached first would govern the service point in typical calendar-based maintenance planning.
  • The 14TL, R121 has the widest production span in the specifications, covering 1976-1983, yet retains the same 6-liter capacity and 45,000 km / 36-month interval as every other listed variant without any mid-range revision.
  • All five variants are designated under normal use conditions, which in coolant service contexts generally refers to standard ambient temperatures and typical driving cycles rather than extreme heat, towing, or sustained high-load operation.
