Peugeot Ion

Coolant capacity & service interval

Peugeot Ion uses coolant with a capacity range of 1,7 to 5,1 liters. The data covers 1 configuration.

The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

TypeSpecifications
Ion (2010-2019)
  • Use: Normal
  • Capacity 5,1 liter (Electric engine/generator control module)
  • Capacity 1,9 liter (Hot water heater fluid (LHD))
  • Capacity 1,7 liter (Hot water heater fluid (RHD))

Additional Notes

  • The Peugeot Ion cooling system carries a total capacity of 5.1 liters for the electric engine and generator control module circuit, a volume that reflects the thermal management demands of power electronics rather than a conventional combustion engine.
  • A separate hot water heater fluid circuit is present alongside the main cooling circuit, with the two circuits operating independently at different capacities rather than sharing a single reservoir.
  • The hot water heater fluid capacity differs by vehicle configuration: left-hand drive variants hold 1.9 liters, while right-hand drive variants hold 1.7 liters, a difference attributable to the repositioning of heater components to suit each steering layout.
  • All three capacity figures listed apply under normal use conditions, meaning no distinction is drawn between standard service fills and more demanding operating environments for this model.
