Opel Astra J 2009-2015 Radiator Coolant Expansion Header Tank & Cap Vehicle Model_Zafira B E Number: 6X0598477One of the lesser known parts on your Opel Astra 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. As it reaches its optimal operating temperature, it expands and can overflow. The expansion reservoir collects this excess fluid and stores it safely instead of letting it spill onto the road.
