Additional Notes
- Both the 110 kW and 130 kW variants of the Proton X50 1.5T share an identical cooling system capacity of 6.83 liters, despite differing in power output.
- A cooling system capacity of 6.83 liters represents a total system fill figure, accounting for the radiator, engine block passages, heater core, and associated hoses rather than the radiator alone.
- The 6.83-liter capacity applies under normal use conditions for both configurations, meaning the figure reflects standard operating environments rather than a modified or severe-duty scenario.
- The 110 kW and 130 kW designations on the Proton X50 1.5T indicate different states of tune within the same 1.5-liter turbocharged engine family, yet the shared coolant capacity suggests a common cooling circuit architecture across both variants.
