Additional Notes

  • The Buick Enclave GM C1XX-2 2.5 and 2.5 AWD share an identical cooling system capacity of 16.9 liters, a figure consistent with a full cooling system service fill encompassing the engine block, cylinder head passages, radiator, heater core, and associated hoses.
  • A 16.9-liter cooling system capacity is relatively substantial for a four-cylinder engine application, reflecting the thermal management demands of a larger crossover platform.
  • The coolant change interval for both the 2.5 and 2.5 AWD configurations is 150,000 km or 60 months under normal use conditions, whichever comes first. The 60-month ceiling means a vehicle driven well below average annual mileage would still reach a change point at the five-year mark.
  • The check interval is specified at 7,500 km for both configurations under normal use, meaning the coolant level and condition are to be inspected at that frequency between full change intervals.
  • Both the front-wheel-drive 2.5 and the all-wheel-drive 2.5 AWD carry the same 16.9-liter capacity and identical service intervals, indicating the addition of the AWD system does not alter the cooling system volume or maintenance schedule for the 2024 model year.
