JAC J6 / Heyue
Coolant capacity & service interval
The JAC J6 / Heyue uses coolant with a capacity ranging from 6 to 7.5 liters depending on the configuration. Four configurations are covered in the data.
The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

Additional Notes
- The Heyue RS 1.8 (2013-2015) carries a fixed cooling system capacity of 7.5 liters, which represents the total volume of coolant the system holds under normal use conditions.
- The JAC J6 / Heyue J6 1.5 VVT, 1.8 VVT, and 2.0 VVT variants, all starting from 2013, share an identical cooling system capacity range of 6-7 liters under normal use conditions.
- A capacity expressed as a range, such as the 6-7 liters listed for the three J6 VVT variants, typically reflects variability introduced by factors like residual fluid retention during a drain, rather than a fixed fill volume.
- The Heyue RS 1.8's fixed 7.5-liter figure stands above the upper bound of the 6-7 liter range shared by the J6 VVT engines, indicating a meaningfully larger cooling system volume despite the shared 1.8-liter displacement between the RS and the J6 1.8 VVT.
- All four configurations are specified under normal use conditions, meaning the listed capacities apply to standard operating environments rather than severe-duty or high-stress service scenarios.
