Additional Notes

  • The Buick Enclave 3.6L V6 cooling system holds 14.7 liters as the standard capacity across all listed configurations from 2017 onward, covering both FWD and AWD variants.
  • When the towing package is equipped, cooling system capacity rises to 16.7 liters, a difference of 2.0 liters that reflects the larger cooler or additional coolant circuit associated with towing-rated hardware.
  • The 7,500 km check interval applies to all four configurations and represents a routine inspection point rather than a full coolant replacement, meaning the system is verified for level and condition at that frequency.
  • Coolant replacement is specified at 150,000 km or 60 months under normal use conditions, whichever comes first. The 60-month ceiling means a vehicle driven fewer kilometers per year would still reach a change interval at the five-year mark.
  • FWD and AWD variants share identical capacity figures and service intervals across all listed model years, indicating no drivetrain-related difference in cooling system volume or maintenance scheduling.
  • The 2017-2022 and 2022-2024 entries for both FWD and AWD configurations carry the same capacity and interval specifications, meaning the 2022 model year appears in both ranges without any change in cooling system data between those groupings.
