Where is the freeze plug that would cause the water to run right thru bell housi on 1995 Ford Taurus

it leaks even when car is not running

Asked by for the 1995 Ford Taurus
On the back of the engine block.
If your freeze plug/plugs on the back of the engine are leaking you can be sure the rest of the freeze plugs in the engine are not far behind.
Where I live I recommend a cooling system service once a year to my customers. If you service the cooling system when you are supposed to you wouldn't have freeze plugs rusting out.
