Citroën C4 Cactus
Coolant capacity & service interval
Citroën C4 Cactus coolant capacity ranges from min to max. Service intervals include normal use. Data covers 2 configurations.
The configuration chart below lists fill volumes and service intervals for each engine and trim variant.
| Type | Specifications |
|---|---|
| C4 Cactus 1.2 PureTech 130, HNS (2018-2022) |
|
| C4 Cactus 1.2 PureTech 130, HNY (2015-2019) |

Additional Notes
- Both the 1.2 PureTech 130 HNS and HNY engine variants share a coolant fill specification described as "between min and max," which refers to maintaining the coolant level within the marked reservoir boundaries rather than filling to a precise measured volume.
- The HNS engine, fitted in the Citroën C4 Cactus from 2018-2022, carries the same min-to-max fill guidance as the earlier HNY unit, indicating a consistent reservoir-based approach across both engine generations of the 1.2 PureTech 130.
- The HNY engine covers a 2015-2019 production window, while the HNS engine spans 2018-2022, meaning there is a two-year period, 2018-2019, during which both engine codes were in use within the C4 Cactus lineup.
- Both variants are listed under normal use conditions, meaning the coolant level specification applies to standard operating environments rather than severe or demanding duty cycles.
- A min-to-max fill specification, as seen across both engine codes, is characteristic of a top-up or service-level check rather than a full system overhaul refill, where a precise total system capacity figure would typically be stated.
