VW Touareg Mk1 2002-2010 Radiator Coolant Expansion Header Tank Vehicle Model_MG ZS 4806949045) in the product specificationOne of the lesser known parts on your VW Touareg 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.
