Lexus LS, XF20 (USA / CAN)

Coolant capacity & service interval

Lexus LS, XF20 (USA / CAN) models require coolant with a capacity range of 10,8 to 11 liters. Service intervals include checks at 8000 km and changes at 48000 km, 72000 km, 30000 miles/ 24 months, and 45000 miles/ 36 months. The data covers 8 configurations.

The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

Additional Notes

  • The Lexus LS 400 (USA) for 1995-1997 carries a cooling system capacity of 11 liters, which is slightly higher than the 10.8 liters specified for all subsequent model years in both the USA and Canadian markets.
  • Starting with the 1998 USA model year, the LS 400 cooling system capacity dropped to 10.8 liters, a figure that remained consistent through 1999-2000 and also applies to the Canadian 1999-2000 specification.
  • The Canadian LS 400 (1999-2000) includes a check interval of 8,000 km alongside the change intervals, whereas the USA specifications for all covered years list only change intervals without a separate check interval.
  • Under normal use conditions, the Canadian LS 400 (1999-2000) specifies a coolant change at 48,000 km, while the first change only condition extends that interval to 72,000 km for the same vehicle.
  • The USA LS 400 specifications across 1995-1997, 1998, and 1999-2000 share a consistent normal-use change interval of 30,000 miles or 24 months, indicating no shift in that interval across those model years despite the capacity change in 1998.
  • For the USA LS 400, the first change only condition extends the coolant change interval to 45,000 miles or 36 months across all covered model years from 1995 through 2000, representing a 50 percent increase over the normal-use mileage interval.
  • A first change only interval reflects the practice of using a factory-fill coolant formulation with a longer initial service life, after which the standard recurring interval applies. In the Canadian specification, the gap between the normal 48,000 km and the first change only 72,000 km interval represents an extension of 24,000 km.
