Additional Notes
- The Lexus GX 460 (URJ150) produced from 2009-2012 carries a single cooling system capacity of 15.4 liters, indicating a fixed-volume system with no listed configuration variants.
- From 2012-2019, the GX 460 (URJ150) cooling system capacity splits into two figures: 13.7 liters for the base configuration and 15.4 liters when a rear heater is fitted, reflecting the additional fluid volume required to circulate coolant through the rear heating circuit.
- The 1.7-liter difference between the two 2012-2019 configurations represents the volume added by the rear heater loop, which extends the coolant circuit beyond the engine and front cabin components.
- Both the 2009-2012 and the rear-heater-equipped 2012-2019 variants share the same 15.4-liter figure, meaning the rear heater option restores the total system volume to the level seen in the earlier production period.
- All rows carry a normal use condition, meaning the listed capacities apply to standard operating environments rather than severe-duty or first-fill scenarios.
