Hongqi HS3
Coolant capacity & service interval
Hongqi HS3 coolant specifications cover a capacity range of 5.6-9.4 liters depending on configuration. The data includes three configurations. The fluid type specified is coolant for normal use.
The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

Additional Notes
- The Hongqi HS3 1.5T carries a coolant capacity range of 8 to 9.3 liters for the main cooling system, while the 2.0T variant holds a fixed 9.4 liters in the same circuit, reflecting the larger displacement engine's greater thermal management demands.
- A separate cooling circuit serving the electric motor on the 1.5T holds between 5.6 and 7.8 liters, a notably wide range that accounts for variation in fill conditions during a standard service procedure.
- The presence of a dedicated electric motor cooling loop on the 1.5T means the total coolant volume across both circuits can reach up to 17.1 liters combined at maximum fill, a figure relevant when planning a full system drain and refill.
- All three rows carry a normal use condition, meaning none of the listed capacities are associated with a severe-duty or first-change interval distinction.
- The 2.0T cooling system capacity of 9.4 liters is a single fixed value rather than a range, suggesting a more consistent fill volume compared to the 1.5T's variable main circuit specification of 8 to 9.3 liters.
