Hongqi EH7

Coolant capacity & service interval

Hongqi EH7 coolant specifications cover a capacity range of 13.5 to 16 liters. The data includes two 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.

TypeSpecifications
  • EH7 111 kWh AWD (2023- )
  • High voltage battery
  • Use: Normal
  • Capacity 13,5-16 liter
  • EH7 85 kWh (2023- )
  • High voltage battery
  • Use: Normal
  • Capacity 13,5-16 liter

Additional Notes

  • The Hongqi EH7 carries a coolant capacity range of 13.5 to 16 liters across both available configurations, a spread that reflects the difference between a service fill and a full system overhaul where air pockets and residual fluid affect the total volume accepted.
  • Both the 85 kWh and the 111 kWh AWD variants share the same 13.5-16 liter capacity range, meaning the addition of the second drive motor in the AWD model does not produce a distinct coolant volume specification.
  • The noted application for both rows is the cooling system serving the high voltage battery, which in electric vehicles is a dedicated thermal circuit separate from any cabin heating loop, designed to maintain battery cells within an optimal operating temperature band.
  • The capacity figures apply under normal use conditions, which in fluid service terminology refers to standard operating environments as opposed to severe or extreme duty cycles that may carry different service parameters.
