Citroen C3 Mk1 2002-2009 Radiator Coolant Expansion Header Tank Vehicle Model_Zafira If you hear a loudOne of the lesser known parts on your Citroen C3 is the coolant expansion tank. This component is responsible for catching and storing coolant overspill from the vehicle's radiator. The coolant in your vehicle is designed to prevent the engine from overheating.
