Need Help! Where is the thermostat located on an 1997 Audi A6 Quarto? And how is it replace? I have a leak that is coming from the back end of the engine in front of the passenger side. My car is overheating and loosing all the water. I believe is the thermostat but don’t know where is located and now the hose has busted as well. Does anyone have a diagram of this egine and the parts for this car is such a hassle.
Thanks!

your engine is the same as the thermostat on a 99 which I just answered... see further up the list ( front of engine pass side)... your problem sounds like one of a couple different things there is a steel coolant pipe that runs behind the engine connecting the heads together either the gasket sprung a leak on the back of the head or there is a hole in the pipe... there is also a coolant pipe that runs under the intake manifold on the pass side that goes to a o ring at the front of the eng pass side, either the o ring could be bad and water is running back to rear of eng or a hole in that pipe... you could have a leaking head gasket ...without seeing the car I can't be more specific, I usually add a dye and a blacklight with special glasses to find leaks good luck & let me know if I can help further
