Additional Notes
- The Hongqi H5 1.5T cooling system carries a capacity of 7.7 liters, while the same engine paired with an electric motor circuit uses a separate 5.6-liter cooling system dedicated to the electric motor.
- The split cooling arrangement on the H5 1.5T hybrid configuration means two distinct coolant volumes are present in the vehicle, totaling 13.3 liters across both circuits combined.
- The H5 1.8T and H5 2.0T share an identical cooling system capacity of 8.2 liters, making the two engine variants equivalent in terms of coolant fill volume.
- The H5 1.5T combustion engine cooling system at 7.7 liters sits below the 8.2-liter figure seen in both the 1.8T and 2.0T variants, reflecting the smaller displacement and associated thermal management requirements of the turbocharged four-cylinder.
- All four cooling system entries across the H5 lineup are rated under normal use conditions, meaning the specified capacities apply to standard operating environments rather than severe-duty cycles.
- A cooling system capacity in the range of 7.7 to 8.2 liters is consistent with a full-system service fill, accounting for the radiator, engine block passages, heater core, and expansion reservoir rather than a partial drain-and-refill procedure.
