Additional Notes
- The Buick Envision E2XX cooling system capacity is 9.4 liters across all listed 2.0-liter configurations, whether front-wheel drive or AWD.
- A 9.4-liter cooling system capacity is a moderately sized fill volume, consistent with a turbocharged four-cylinder engine paired with a full coolant circuit including heater core and reservoir.
- The AWD configurations share an identical 9.4-liter capacity with their front-wheel drive counterparts, indicating the addition of rear-drive hardware does not alter the primary cooling circuit volume.
- Under normal use conditions, the specified coolant change interval is 150,000 miles or 60 months, whichever comes first, placing it among the longer-life service schedules typical of modern extended-life coolant formulations.
- The 60-month time limit on the coolant change interval means a calendar-based threshold of five years applies regardless of mileage accumulation, which is relevant for low-mileage vehicles.
- A coolant check interval of 7,500 miles is specified separately from the change interval, establishing a routine inspection cadence well ahead of the full replacement schedule.
- The 2020-2022 and 2022-onward rows for both the FWD and AWD 2.0-liter configurations carry identical capacity and interval specifications, showing no change in cooling system service requirements at the 2022 model year boundary.
