Vauxhall Ampera, R12

Coolant capacity & service interval

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

Additional Notes

  • The Vauxhall Ampera (2011-2016) runs three separate coolant circuits, each with its own capacity figure: 6.3 liters for the combustion engine cooling system, 6 liters for the high voltage battery cooling system, and 3 liters for the power electronics cooling system.
  • The combustion engine circuit holds the largest volume at 6.3 liters, which reflects the thermal demands of a petrol engine compared to the battery and electronics circuits.
  • The high voltage battery cooling system capacity of 6 liters is close to the combustion engine figure, indicating a substantial dedicated loop for managing battery temperature rather than a shared or supplementary arrangement.
  • At 3 liters, the power electronics cooling system holds half the volume of the high voltage battery circuit, consistent with the smaller thermal mass of inverters and related components relative to a full battery pack.
  • All three circuits share an identical service schedule under normal use conditions: a check interval of 12 months and a change interval of 240,000 km or 60 months, whichever comes first.
  • The 60-month change interval across all three circuits translates to a five-year coolant replacement cycle, which is a relatively extended interval made possible by long-life coolant formulations designed to resist degradation over time.
  • The 240,000 km distance threshold paired with the 60-month time limit means the interval is governed by whichever limit is reached first, so lower-mileage use does not extend the time beyond five years.
  • Annual checks across all three circuits, regardless of mileage, reflect the importance of monitoring coolant condition and level in a multi-circuit thermal management system where each loop serves a distinct and critical function.
