Additional Notes
- The Hongqi HQ9 2.0T, starting from 2023, carries a cooling system capacity of 12.4 liters, which represents a full system fill volume encompassing the radiator, engine block passages, heater core, and expansion reservoir combined.
- A 12.4-liter coolant capacity is on the higher end for a turbocharged four-cylinder engine, reflecting the HQ9's larger vehicle architecture and the extended circuit length typical of full-size premium SUVs.
- The 12.4-liter figure applies under normal use conditions, meaning the specified volume is intended for standard operating environments rather than severe-duty or high-thermal-stress scenarios.
