BYD Song Pro, S2

Coolant capacity & service interval

BYD Song Pro and S2 models utilize coolant with a capacity range of 2,6 to 18 liters. Service intervals require a change every 10000 km or 48 months. The data covers 4 configurations.

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

Additional Notes

  • The BYD Song Pro 118 kW and 136 kW variants share an identical cooling system capacity of 7 liters, indicating the same cooling circuit architecture despite the difference in power output between the two engine configurations.
  • Both the 118 kW and 136 kW Song Pro variants follow a coolant change interval of 10,000 km or 48 months under normal use conditions, meaning whichever threshold is reached first would trigger a service event.
  • The Song Pro DM carries a substantially larger cooling system than the non-DM variants, holding 17 liters in 2WD form compared to 7 liters in the combustion-only models, reflecting the added thermal management demands of a dual-mode hybrid powertrain.
  • The 4WD configuration of the Song Pro DM requires 18 liters of coolant, one liter more than the 2WD version, a difference attributable to the additional cooling circuit associated with the rear drive unit.
  • The Song Pro DM shares the same 10,000 km or 48-month change interval as the non-DM variants under normal use conditions, applied to the main cooling system.
  • The Song Pro DM carries a separate battery cooling system with a capacity of 2.6 liters, a dedicated circuit isolated from the main engine cooling system to manage thermal conditions in the high-voltage battery pack.
  • No change interval is listed for the Song Pro DM battery cooling system, meaning the 2.6-liter capacity figure applies strictly as a fill reference rather than a scheduled service specification.
