BYD L3

Coolant capacity & service interval

BYD L3 coolant capacity is 6,8 liters. Service intervals include checks at 3000 km or 10000 km/6 months and changes at 20000 km/12 months. The data covers 6 configurations.

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

Additional Notes

  • Across all three engine variants of the BYD L3 covered in the 2010-2015 range, the cooling system capacity is 6.8 liters, a figure that applies uniformly regardless of displacement or power output.
  • The 6.8-liter figure represents a service fill capacity, meaning the volume of coolant the system holds during normal operation rather than a full overhaul or dry-fill measurement.
  • Under normal use conditions, the cooling system calls for a check interval of every 10,000 km or 6 months, whichever comes first, with a full coolant change scheduled at 20,000 km or 12 months.
  • An initial service interval of 3,000 km is specified for a coolant check across all listed engine variants, applying only to the early break-in period rather than the ongoing normal service schedule.
  • The 1.5-liter engine appears in two distinct output ratings within the same model years: 79 kW under engine code QCJ7153A, and 80 kW under codes QCJ7153A5/A6/A7 and BYD7153A/A1. Despite the difference in power output, both share identical cooling system capacities and service intervals.
  • The 1.8-liter variant, identified by engine code QCJ7183A4, carries the same 6.8-liter cooling system capacity and the same check and change intervals as the 1.5-liter configurations, indicating no scaling of coolant volume with the larger displacement in the BYD L3 lineup.
  • The dual-condition service structure, separating an initial 3,000 km check from the recurring 10,000 km/6-month check cycle, reflects a common practice of verifying system integrity shortly after a new fill before transitioning to standard maintenance intervals.
