Additional Notes

  • The Cadillac XT4 2.0 cooling system holds 9.5 liters across all listed configurations, covering both front-wheel drive and AWD variants from 2018 onward.
  • A 9.5-liter cooling system capacity is consistent with a turbocharged four-cylinder engine of this displacement class, reflecting the total volume of coolant circulating through the engine block, cylinder head, radiator, and associated passages.
  • The AWD variants share an identical 9.5-liter cooling system capacity with the standard 2.0 configurations, indicating no measurable difference in coolant volume between the two drivetrain layouts.
  • The specified change interval for all listed configurations is 150,000 miles or 60 months under normal use conditions, placing the XT4 2.0 cooling system in the long-life service category.
  • A 60-month interval tied to the 150,000-mile threshold means whichever limit is reached first governs the service point, which is standard practice for time-and-distance coolant replacement schedules.
  • The 2022-onward entries carry the same 9.5-liter capacity and 150,000-mile / 60-month interval as the 2018-2022 entries, showing no specification change at the 2022 model year boundary for either drivetrain configuration.
