I know this sounds kind of dumb but this is what forums are tohelp right.. i know the whole procedure on how to flush the radiator but i cant find the valve to let the water out of my radiator. I have a 2002 Audi TT quattro 1.8 liters with 180 hp. Im trying to get help on where the the valve is to let the water out of the radiator. can any one help me?

 

back bottom driverside of the radiator. There is a **** you just pull and it will flow on out.
