Opel Ampera, R12

Coolant capacity & service interval

Opel Ampera and R12 models utilize coolant with a capacity range of 3 to 6,3 liters. Service intervals consist of checks every 12 months and changes every 240000 km or 60 months. The data covers 3 configurations.

The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

Additional Notes

  • The Opel Ampera (2011-2016) runs three separate coolant circuits, each with its own capacity and service schedule, reflecting the vehicle's extended-range electric architecture.
  • The combustion engine cooling system holds 6.3 liters, the largest of the three circuits, which aligns with the thermal demands of a petrol engine used as a range extender.
  • The high voltage battery cooling system carries a 6-liter capacity, only 0.3 liters less than the combustion engine circuit, indicating a substantial dedicated thermal management loop for the battery pack.
  • The power electronics cooling system has a 3-liter capacity, half that of the battery circuit, consistent with the smaller fluid volume typically required to manage inverter and power conversion hardware.
  • All three circuits share an identical change interval of 240,000 km or 60 months under normal use conditions, meaning a single service event can address all three systems simultaneously on a mileage or time basis.
  • The 60-month change interval translates to a five-year cycle, which is longer than the 12-month check interval applied to all three circuits, indicating that visual or level inspections are expected annually between full fluid changes.
  • The total coolant volume across all three circuits combined reaches 15.3 liters, a figure relevant when planning a full-system service or overhaul requiring complete fluid replacement across the entire vehicle.
