Lexus LM (EU)

Coolant capacity & service interval

Lexus LM (EU) coolant capacity ranges from 1,3 to 8,5 liters. Service intervals include checks at 30000 km or 24 months, and changes at 90000 km, 150000 km, or 240000 km. The data covers 4 configurations.

Additional Notes

  • The Lexus LM (EU) 350h AWD cooling system holds between 8.4 and 8.5 liters, a range that reflects minor variation in fill level depending on how completely the system is purged during a service drain.
  • Under normal use conditions, the main cooling system on the LM 350h AWD follows a change interval of 90,000 km, with checks scheduled every 30,000 km.
  • The first change only condition extends the initial coolant change interval on the main cooling system to 150,000 km, which is 60,000 km longer than the subsequent normal-use interval of 90,000 km.
  • The inverter cooling circuit on the LM 350h AWD is a separate system with a much smaller capacity of 1.3 liters, reflecting the compact and self-contained nature of hybrid inverter thermal management.
  • Checks for the inverter cooling system are scheduled at 30,000 km or every 24 months, whichever comes first, introducing a time-based criterion not present in the main cooling system check schedule.
  • Under normal use, the inverter cooling system shares the same 90,000 km change interval as the main cooling system, despite the significant difference in fluid volume between the two circuits.
  • The first change only interval for the inverter cooling system is set at 240,000 km, which is substantially longer than the 150,000 km first-change interval applied to the main cooling system on the same vehicle.
