  • Use: Normal
  • Capacity 16,9 liter
  • Change 150000 miles/ 60 months

Additional Notes

  • The GMC Acadia C1XX-2 2.5 and 2.5 AWD share an identical cooling system capacity of 16.9 liters, indicating a full system fill volume that accounts for the radiator, engine block, heater core, and associated hoses rather than a partial or top-off quantity.
  • A 16.9-liter cooling system capacity is relatively substantial for a four-cylinder application, reflecting the thermal management demands of a crossover platform designed to handle both passenger comfort heating and engine temperature regulation across varied driving conditions.
  • The coolant change interval for both the 2.5 and 2.5 AWD configurations is rated at 150,000 miles or 60 months under normal use conditions, placing the service interval in the extended-life category typical of modern OAT or HOAT-type coolant formulations.
  • The 60-month time limit on the coolant change interval means that calendar age serves as an independent trigger alongside mileage, so whichever threshold is reached first governs the service requirement regardless of how the vehicle is driven.
  • No capacity difference exists between the front-wheel-drive 2.5 and the AWD variant, confirming that the addition of all-wheel-drive hardware does not alter the cooling system volume in the 2024 Acadia under the C1XX-2 platform.
