Additional Notes

  • The Lexus LS 430 (XF30, EU) cooling system holds 9.8 liters for the 2000-2001 model years, a figure that reflects a full system fill including the engine block, radiator, and associated hoses.
  • From 2002 onward, the cooling system capacity for the LS 430 shifts to a range of 9.5-10.1 liters rather than a fixed value, indicating that minor variation exists across individual units within the same model year group.
  • For 2000-2001 models under normal use conditions, coolant replacement is specified at 30,000 km or 24 months, whichever comes first, representing a relatively short interval tied to conventional coolant degradation rates.
  • The first change only designation for 2000-2001 models carries an extended interval of 60,000 km or 36 months, meaning the factory-fill coolant is treated as having a longer initial service life before the standard normal-use cycle begins.
  • The same first change only interval of 60,000 km or 36 months applies to 2002-2003 models, with the normal-use interval remaining at 30,000 km or 24 months for subsequent changes.
  • Starting with the 2003-2006 specification group, a periodic check at every 30,000 km is introduced alongside a significantly extended change interval of 90,000 km under normal use, a pattern consistent with the adoption of long-life coolant formulations.
  • Under the first change only condition for 2003-2006 models, the change interval extends further to 150,000 km, while the 30,000 km check interval remains in place, reflecting a factory-fill coolant rated for substantially longer service before initial replacement.
  • The shift from a time-and-distance combined interval in 2000-2003 specifications to a distance-only change interval with a separate check milestone in 2003-2006 specifications represents a structural change in how coolant service is scheduled across the production run.
