Additional Notes

  • The Lexus LX 600 AWD carries a main cooling system capacity of 14.7 liters, a figure that reflects a full service fill for the primary engine cooling circuit.
  • A separate intercooler cooling circuit on the LX 600 AWD holds 3.8 liters, indicating a dedicated secondary loop for charge air cooling rather than a shared volume with the main system.
  • Canadian-market specifications call for coolant checks every 8,000 km, while USA-market specifications set the check interval at every 15,000 miles or 18 months, reflecting a meaningful difference in scheduled inspection frequency between the two markets.
  • The Canadian-market change interval for both the main cooling system and the intercooler circuit is 160,000 km or 120 months under normal use conditions.
  • Under normal use conditions, the USA-market change interval for the main cooling system is 50,000 miles or 60 months, which is notably shorter than the first-change-only interval of 100,000 miles or 120 months specified for the same circuit.
  • The first-change-only designation on the USA-market rows means the extended 100,000-mile or 120-month interval applies exclusively to the initial coolant drain and fill, after which the standard 50,000-mile or 60-month normal interval governs subsequent changes.
  • The intercooler circuit on the USA-market LX 600 AWD follows the same dual-interval structure as the main cooling system, with a normal change at 50,000 miles or 60 months and a first-change-only interval of 100,000 miles or 120 months, both at the same 3.8-liter capacity.
