yeah, we got it figured out now ..
next is to find out what it really is - the source of the leak. 
you'll see my other post . 
maybe it is just a hose.

  Well, then I mean the Coolant distributor if that's what it's called.  It's connected to the
  bottom of that.

    i figured that must mean   t-stat housing.

    the only other 'stack' in a 2.1 cooling system is the 'coolant distribution
    tower' .....
    or just 'coolant distributor ' .......hidden behind firewall on right side.

        Hi Scott,

        Thanks for your input.  The hose is on the passenger side and is attaches
        at
        the bottom of the T-stack right next to
        a heater hose.  It goes about 8 inches or so and then connects to one of
        the
        long metal pipes going forward to the
        radiator.
