BYD F6

Additional Notes

• The BYD F6 cooling system carries two distinct capacity figures: a dry fill and a service fill. The dry fill represents the total volume of a completely drained and refilled system, while the service fill reflects the smaller volume typically displaced during a routine coolant change where residual fluid remains in the system.
• On the 2.0 16V QCJ7200E engine, the dry fill capacity is 6.8 liters, whereas the service fill sits at 4.9 liters, a difference of 1.9 liters that reflects how much coolant stays trapped in the block, heater core, and hoses during a standard drain.
• The 2.4 16V QCJ7240E engine carries a higher dry fill capacity of 7.2 liters, while sharing the same 4.9-liter service fill figure as the 2.0-liter variant. The larger displacement engine therefore holds nearly 300 ml more coolant at full system capacity.
• Under normal use conditions, both engine variants follow a check interval of 10,000 km or 6 months, whichever comes first, paired with a change interval of 40,000 km or 24 months.
• An initial service check interval of 3,000 km applies to both the 2.0 16V and 2.4 16V engines, a significantly shorter interval than the 10,000 km normal check schedule, reflecting the closer attention given to a cooling system in its early operating period.
• The 40,000 km or 24-month change interval under normal use conditions applies equally across both engine variants, meaning neither the 2.0-liter nor the 2.4-liter configuration carries a more frequent coolant replacement requirement despite the difference in dry fill volume.
