well then I may have been wrong Trace it out and see where its is coming from and going to.

Let the engine run and get to operating temp feel the hose to see if its hot

I just had this problem with my 2007 Expedition. I got out of the truck one night and smelled coolant, so I open the hood and see fresh coolant coming out of the heater hose T joint. It was causing a small misfire as well due to the liquid pooling. The correct part number you need from ford is KH509. It cost me $39.16 on Ebay for genuine Motorcraft and $60 dollars labor to install at a local repair place.

looks like a heater core line

what you are pointing at is a heater hose. if it looks like oil is coming out of it maybe you need to replace your antifreeze. it can turn brown or black if its really old.
