Additional Notes
- The BYD Atto 3 60.5 kWh cooling system holds between 3.8 and 4 liters of coolant, a range that reflects normal variation during a service fill depending on residual fluid left in the system.
- The 0.2-liter spread between the minimum and maximum capacity figures suggests a relatively tight tolerance for the cooling circuit, consistent with the compact thermal management architecture found in battery electric vehicles.
- Under normal use conditions, a coolant level check is specified at every 20,000 km or 12 months, whichever comes first.
- The full coolant change interval under normal use is set at 100,000 km or 48 months, meaning a single change cycle spans four years of regular operation before a fluid replacement is due.
- The 48-month change interval is notably longer than the 12-month check interval, so multiple inspections are expected to occur between each full drain-and-refill service.
