Additional Notes

  • The Lexus LS 400 (USA) cooling system holds 10.6 liters for the 1990-1992 model years, while the 1993-1994 model years carry a slightly larger capacity of 10.8 liters.
  • A 10.6-liter cooling system capacity, as seen on the 1990-1992 LS 400, represents a full-system service fill volume, accounting for the radiator, engine block passages, heater core, and associated hoses.
  • Under normal use conditions, the coolant change interval across all 1990-1994 model years is 30,000 miles or 24 months, whichever comes first.
  • A "first change only" interval of 45,000 miles or 36 months applies to all 1990-1994 model years, meaning the initial factory-fill coolant is rated to last longer before the first service than subsequent refills under normal conditions.
  • The 0.2-liter increase in cooling system capacity between the 1992 and 1993 model years, moving from 10.6 to 10.8 liters, reflects a minor revision to the cooling circuit volume on the LS 400.
  • The 1993 and 1994 LS 400 share identical cooling system specifications, with a 10.8-liter capacity and the same normal and first-change-only intervals of 30,000 miles/24 months and 45,000 miles/36 months respectively.
  • The gap between the normal interval of 24 months and the first-change-only interval of 36 months indicates the factory coolant fill on all covered model years was formulated or conditioned to withstand an additional 12 months or 15,000 miles beyond the standard service cycle.
