I don’t believe there is one. Otherwise, why would you have to go through all this? http://ww2.justanswer.com/uploads/s420/2010-03-12_025904_01_Taurus_Cooling_System_Draining,_Filling_and_Bleeding.pdf
Instead of doing all this, do the following: Get the engine up to operating temperature. With the engine idling loosen the upper radiator hose clamp. Take a small flat bladed screwdriver and insert it between the upper radiator hose and the hose neck on the radiator. Allow the engine to continue to idle until all the air is purged from the cooling system where nothing but coolant comes out. Remove the screwdriver and retighten the hose clamp. Check the coolant level after the engine cools off.
