A used OEM Audi Coolant Reservoir / Tank / Bottle, part number 8E0121403F, from a 4.2L V8-powered RS4 or S4. This expansion tank stores and deaerates coolant in the pressurized cooling system. Over time, the plastic can become brittle and develop cracks at the neck or seam, leading to coolant loss and overheating. Fits the 4.2L 4163CC and 4172CC naturally aspirated V8 engines.
