Additional Notes

  • The BYD Song Plus 118 kW and 136 kW variants share an identical cooling system capacity of 9 liters, indicating a common cooling architecture across both power outputs despite their differing engine ratings.
  • A 9-liter cooling system capacity is characteristic of a conventional internal combustion engine layout, where the coolant circuit covers the engine block, cylinder head, radiator, heater core, and associated plumbing.
  • The Song Plus EV Champion Edition variants, identified by chassis codes BYD6483SBEV and BYD6483SBEV1, carry a significantly smaller cooling system capacity of 4 liters, which reflects the reduced thermal management demands of an electric drivetrain compared to a combustion engine.
  • A 4-liter coolant capacity in an electric vehicle typically serves components such as the battery pack, power electronics, and electric motor rather than a combustion engine, resulting in a more compact circuit.
  • All four configurations share the same service interval under normal use conditions: a coolant change at 100,000 km or 48 months, whichever comes first.
  • The 48-month time limit on the coolant change interval means that even if a vehicle accumulates low mileage, the coolant is due for replacement after four years of service under normal use conditions.
  • The alignment of service intervals across both combustion and electric variants suggests a standardized maintenance schedule for the cooling system regardless of drivetrain type, with the 2020 starting year applying to all listed configurations.
