Additional Notes

  • The Buick Envista VSS-F cooling system capacity differs between engine variants, with the 1.2 Turbo holding 6 liters and the 1.2 Turbo FlexFuel requiring a slightly larger 6.3 liter fill.
  • A 6 to 6.3 liter cooling system capacity is consistent with a service fill figure, meaning the volume needed when refilling a drained but otherwise intact system rather than a full overhaul or block flush.
  • Both variants share the same change interval of 150,000 miles or 60 months under normal use conditions, placing the coolant in a long-life service category.
  • The 60-month time limit runs parallel to the mileage threshold, so whichever of the two is reached first would govern the change interval under normal use.
  • The 1.2 Turbo FlexFuel variant, introduced for the 2024 model year, carries an additional coolant check interval of 7,500 miles that is absent from the standard 1.2 Turbo specification.
