Additional Notes

  • The Cadillac ELR (USA / CAN) carries three separate coolant circuits: one for the combustion engine, one for the high voltage battery, and one for the power electronics. Each circuit holds a distinct fluid volume and is serviced independently.
  • The combustion engine cooling system holds 7.3 liters across both the 2013-2014 and 2014-2016 configurations. A capacity at that level is consistent with a full system fill that accounts for the radiator, hoses, reservoir, and engine block passages.
  • The high voltage battery cooling system carries a capacity range of 5.8-6 liters rather than a fixed value. A range like this typically reflects minor variation in fill volume depending on bleed procedures or system state at the time of service.
  • The power electronics cooling system holds 2.8 liters, the smallest of the three circuits. A capacity in that range reflects a more compact loop dedicated to managing heat from inverters and related drive components rather than a large thermal mass like the engine or battery pack.
  • All three cooling circuits share an identical service interval of 150,000 miles or 60 months under normal use conditions. Aligning all three intervals simplifies scheduling, as a single service event can address all coolant circuits simultaneously.
  • The 60-month time limit on the coolant change interval means that calendar age alone can trigger a service requirement before the mileage threshold is reached, which is relevant for lower-mileage vehicles driven infrequently.
  • The specifications for 2013-2014 and 2014-2016 show identical capacities and intervals across all three cooling circuits, indicating no change in coolant system volume or service scheduling between those two overlapping model year groupings.
