To replace the thermostat on a Citroën C4, open the bonnet to access the components located inside the engine bay: on the right side, you will find the hose that allows the coolant to flow. By disconnecting the hose from its fitting, you will locate the underlying thermostat, which should then be pulled out of its housing; after removing the old thermostat, you can insert the new replacement part.

Then, reposition the hose to ensure everything functions correctly.
