Being a 2001 Allroad, I'm assuming you have the 2.7TT engine. If so, the thermostat is located on the front of the engine block behind a black plastic plate. just left of the water-pump. Unfortunately, it is a very difficult part to get to, and it takes some special tools in order to replace it properly. If you've never replaced your water-pump and you're past 75,000 miles, your car is essentially a ticking time-bomb. You should look into getting it replaced along with the timing belt and thermostat.
