Additional Notes

  • All cooling system configurations across the GMC Acadia lineup share a uniform change interval of 150,000 miles or 60 months under normal use conditions, regardless of engine displacement, drivetrain, or trim level.
  • The 2.5-liter engine in the 2016-2017 Acadia carries a cooling system capacity of 11.3 liters, a notably higher figure than the same engine in subsequent model years, where capacity drops to 9.2 liters without a rear heater.
  • For the 2.5-liter engine from 2017-2018, the rear heater option raises total cooling system capacity from 9.2 liters to 10.7 liters, while the 2018-2021 version of the same engine shows a slightly lower rear-heater figure of 10.2 liters, indicating a mid-cycle revision to the circuit volume.
  • The 2.0-liter four-cylinder configurations from 2019-2023 list a capacity range of 9.0 to 10.6 liters with the rear heater notation, meaning the lower value represents the base cooling circuit and the upper value accounts for the additional fluid volume when a rear heater is installed.
  • The 3.6 V6 in 2016-2018 FWD configurations carries a capacity range of 11.3 to 12.9 liters, which is the widest single-range spread among all engine entries and reflects the variation introduced by optional rear heating circuits in that generation.
  • From 2018 onward, the 3.6 V6 FWD cooling system capacity shifts to a range of 10.6 to 12.2 liters, a reduction at both the lower and upper bounds compared to the 2016-2018 specification, consistent with a platform or packaging change between generations.
  • The 3.6 V6 FWD and AWD configurations from 2022-2023 share an upper capacity value of 13.0 liters with the rear heater, which is the highest single capacity figure listed across all Acadia cooling system entries in the specifications.
  • The 3.6 V6 AWD entry for 2016-2017 lists a fixed capacity of 11.3 liters with no range, while the 2017-2018 AWD entry introduces a range of 11.4 to 12.9 liters with the rear heater notation, indicating the rear heater option was not reflected in the earlier AWD specification.
  • Denali trim configurations for the 3.6 V6 from 2017 onward carry identical capacity ranges to their non-Denali AWD counterparts within the same model year brackets, meaning the Denali designation does not alter the cooling system volume specifications.
  • The capacity notation "+ rear heater" appears across the 2.0-liter, 2.5-liter (from 2017), and all 3.6 V6 AWD and Denali entries, indicating the rear heater circuit adds measurable fluid volume to the total cooling system fill requirement in those configurations.
