As the auxiliary part of your engine cooling system, Audi A6 Radiator Expansion Tank comes in handy to minimize coolant wastage or loss once it expands with excessive engine heat. Coolant fluid stays on its reservoir when not in used. The fluid is then released through the valves when predetermined operating temperature has been reached requiring efficient heat dissipation. As the coolant routes through your engine system channels, it absorbs the heat which it then vented off through the radiator and cooling fans. This mechanism goes until allowable range of temperature has been reached. Through the process, the coolant may expand and may fill and spill from your stock reservoir. The need to save overfilling and expanded coolant best explains the practical use of your radiator expansion tank.
