Citroën C-Zero
Coolant capacity & service interval
Citroën C-Zero coolant specifications cover normal use with capacities of 5.1 liters for the electric engine/generator control module, 1.9 liters for the hot water heater fluid in left-hand drive models, and 1.7 liters for the hot water heater fluid in right-hand drive models. The data covers 2 configurations.
The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

Additional Notes
- The Citroën C-Zero cooling system is divided into separate circuits, each carrying its own fluid capacity rather than sharing a single unified reservoir.
- The electric engine and generator control module circuit holds 5.1 liters across both the 2010-2016 and 2016-2020 model ranges, making it the largest single coolant volume in the system.
- The hot water heater circuit, used for cabin heating, carries a noticeably smaller volume than the drivetrain cooling circuit, at 1.9 liters on left-hand drive configurations.
- Right-hand drive variants of the C-Zero carry 1.7 liters in the hot water heater circuit, a modest reduction of 0.2 liters compared to left-hand drive models, likely reflecting differences in plumbing routing between the two configurations.
- All listed capacities apply under normal use conditions, meaning no separate severe-duty interval or fill volume is specified for either generation.
- The capacity figures remain identical between the 2010-2016 and 2016-2020 generations, indicating no change to coolant circuit sizing across the full production span covered by these specifications.
