BYD Seal

Coolant capacity & service interval

BYD Seal coolant capacity ranges from 4,6 to 5,8 liters. Service intervals consist of 20000 km or 12 months and 100000 km or 48 months. The data covers 6 configurations.

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

Additional Notes

  • The BYD Seal electric motor cooling system holds 5.1 liters of coolant on the standard rear-wheel-drive configuration introduced in 2022, while the AWD variant carries a larger 5.8-liter capacity, reflecting the additional thermal management demands of a second motor.
  • The Seal Champion Edition and Seal Champion Edition AWD, both introduced in 2023, share the 5.8-liter electric motor cooling system capacity, placing them in the same capacity class as the Seal AWD rather than the base rear-wheel-drive model.
  • Variants noted as covering the electric motor cooling system carry a 20,000 km or 12-month change interval under normal use conditions, whichever comes first. The 12-month time limit means calendar aging is treated as equally significant as mileage accumulation.
  • The Seal 84 kWh and Seal AWD 84 kWh, both introduced in 2023, list a capacity range of 4.6 to 5.0 liters rather than a fixed value. A range specification of this kind typically reflects variation between cooling circuit configurations or fill method differences during service.
  • The 84 kWh variants carry a substantially extended change interval of 100,000 km or 48 months under normal use conditions, compared to the 20,000 km or 12-month interval on other Seal configurations. A 48-month interval spans four full calendar years between scheduled coolant changes.
  • The 84 kWh variants are noted only as covering the general cooling system, without the additional electric motor notation present on other rows. The absence of that notation corresponds with the differing capacity figures and the longer service interval on those configurations.
