Where is thermostat on Audi A6?

The automotive thermostat is a temperature controlled on and off valve. When the temperature rises to a predetermined temperature, the thermostat opens up to allow the engine coolant to flow through the cylinder block and the radiator. This flow is crucial to maintain optimum operating temperature for fuel efficiency, enhanced driveability, and engine protection. The coolant flow is reduced when the engine is cold, and the flow is increased when the engine is hot. Contrary to popular opinion, operating the vehicle without the thermostat doesn't make the engine run cooler. It will actually run hotter because there isn't a thermostat to slow the coolant flow. This means the coolant doesn't stay in the radiator long enough to dissipate its heat.
To replace thermostat on Audi A6 model.The Thermostat is behind the timing belt. Usually it is replaced along with the timing belt job at about 75K miles. As a stand alone job on a 2.8L V-6 it should be about a 3 hour job and maybe $40 for the thermostat, and about $20 for coolant.
