Additional Notes

  • The Mazda Luce/Legato/929L (EU) coolant system capacities range from 6.5 to 7.6 liters across the model range, with all figures representing full cooling system fills rather than partial service quantities.
  • The Luce 1500 SUA (1966-1972) carries the smallest cooling system capacity in the lineup at 6.5 liters, reflecting the smaller displacement of the 1500cc engine relative to the 1800cc variants.
  • The Luce 1800 SVA (1968-1973) has the largest cooling system capacity at 7.6 liters, slightly above the 7.5-liter figure shared by all subsequent Luce Legato and 929L variants regardless of engine displacement.
  • All Luce Legato and 929L variants from 1973 onward, covering both the 1800cc and 2000cc engines across the LA2/3 and LA4/5 series, share an identical cooling system capacity of 7.5 liters.
  • The LA2/3 series, spanning 1973-1977 for the 1800 and 1975-1977 for the 2000, carries a coolant change interval of 48,000 km or 24 months under normal use conditions, whichever comes first.
  • The LA4/5 series (1977-1981) for both the 1800 and 2000 engine variants specifies a shorter coolant change interval of 40,000 km or 24 months under normal use conditions, compared to the 48,000 km distance interval of the earlier LA2/3 series.
  • The time-based component of the coolant change interval remains fixed at 24 months across all LA2/3 and LA4/5 variants, meaning the interval reduction between generations affected only the distance threshold, not the calendar limit.
  • No coolant change interval is listed for the Luce 1500 SUA (1966-1972) or the Luce 1800 SVA (1968-1973), as the specifications for those earlier models record only system capacity.
