Additional Notes
- The BYD Song DM cooling system holds 16.3 liters of coolant, a capacity consistent with a full system fill covering the engine, heater core, reservoir, and all associated passages.
- The 16.3-liter figure represents a cooling system capacity rather than a partial or top-up volume, meaning a complete drain and refill procedure would require the full amount to restore proper coolant level and mixture ratio.
- Under normal use conditions, the Song DM (2017-2019) carries a coolant change interval of 10,000 km or 48 months, whichever comes first, placing the time-based limit at four years regardless of distance accumulated.
- The 48-month time limit on the normal-use interval reflects the chemical degradation of coolant additives over time, which occurs independently of mileage and affects corrosion protection and freeze point stability.
- The normal-use designation tied to the 10,000 km / 48-month interval applies to the Song DM across the 2017-2019 model years without variation in either capacity or service schedule within that range.
