BYD QIN
Coolant capacity & service interval
BYD QIN uses coolant with a capacity range of 4 to 7,8 liters. Service intervals occur every 100000 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 Qin 113 kW and 80 kW variants, both covering 2019-2022, share an identical cooling system capacity of 6.2 liters, indicating no differentiation in coolant volume between the two power outputs for service fill purposes.
- Both the 113 kW and 80 kW combustion variants follow a normal-use service interval of 100,000 km or 48 months, whichever comes first, reflecting a standard long-life coolant replacement schedule.
- The Qin EV 450 (2018-2022) carries two separate cooling circuits, each with its own capacity and service interval, distinguishing the electric motor circuit from the high voltage battery circuit.
- The electric motor cooling circuit on the Qin EV 450 holds 7.8 liters, a notably larger volume than the 6.2-liter figure seen in the combustion variants, consistent with the thermal management demands of an electric drive unit.
- The high voltage battery cooling circuit on the Qin EV 450 holds 4 liters, a smaller dedicated volume serving solely the battery pack's thermal regulation needs.
- Both cooling circuits on the Qin EV 450 share the same service interval of 100,000 km or 48 months under normal use conditions, aligning the replacement schedule across the two separate systems.
- Across all four configurations, the 48-month time limit applies regardless of mileage accumulation, meaning a vehicle driven infrequently would still require coolant replacement at the four-year mark under normal use conditions.
