Additional Notes
- The Citroën C4 III coolant specifications cover three PureTech petrol engine variants: the 100 hp (HNE), 130 hp (HNS), and 155 hp (HNJ).
- All three engine variants share the same coolant fill guidance, which calls for a level maintained between the minimum and maximum marks rather than a fixed volume figure.
- A "between min and max" specification is typical of a top-up or service-level check rather than a full system drain and refill capacity, meaning no single absolute litre value is assigned to the cooling system fill for these configurations.
- All three configurations carry a normal use condition, meaning the coolant level guidance applies under standard operating circumstances rather than a separate severe-duty or first-fill scenario.
- The 1.2 PureTech engine family spans three distinct power outputs across the C4 III lineup, yet the cooling system service approach remains consistent across all of them.
