NIO ET7

Coolant capacity & service interval

NIO ET7 coolant capacity ranges from 14 to 14,25 liters. Service intervals include checks at 40000 km/24 months and 100000 km/60 months. The data covers 4 configurations.

Additional Notes

  • The NIO ET7 100 kWh variant carries a cooling system capacity of 14 liters, while the 75 kWh variant holds a slightly larger 14.25 liters, making the two battery configurations distinct in their coolant volume requirements.
  • On the ET7 100 kWh, the first coolant check is scheduled at 100,000 km or 60 months, whichever comes first, reflecting a longer initial service interval before the recurring cycle begins.
  • After the first check on the ET7 100 kWh, subsequent coolant checks follow a 40,000 km or 24-month interval, a considerably shorter cycle than the opening service period.
  • The ET7 75 kWh follows the same interval structure as the 100 kWh variant, with a first check at 100,000 km or 60 months and subsequent checks every 40,000 km or 24 months.
  • A 14.25-liter cooling system capacity on the 75 kWh variant is a service fill figure, representing the volume of coolant the system holds during a standard maintenance fill rather than a full mechanical overhaul quantity.
  • The gap between the first-check interval of 60 months and the subsequent interval of 24 months means the recurring service cycle is roughly 2.5 times more frequent than the initial one, across both battery configurations.
