This is in the front of my 06 right behind the lower front bumper. I took a couple pics kind of like I was zooming into it. Its seems to be leaking maybe but not sure what it would be.

 

It's part of the lines that go to or from the trans cooler that's up in the grille area. Mine's been seeping a little fluid, not enough to actually leave a drop on the ground, for a good year now. I wouldn't worry about it.

sharp truck!

 

I thought that was the power steering line, may want to check again and trace it out, also see how your power steering fluid level is if you have puddles.

 

It is the power steering. They used to have an actual cooler attached, but just went to the tubing alone.

 

its either power steering or transmission. Mine has a radiator there... but I have the towing package, maybe if you don't have the towing package they just put a pipe on?

PS - nice haircut!

 

power steering. fords been running little cooler lines like that for a while now, my 90 mustang has that. the trans cooler is above that, that is the little radiator lookin thing. its the ps line.

 

Trannie cooler is under the hood behind the bumper. The 04 had a finned PS cooler, but in 05 or 06 they changed it to just the tubes.

Here are pics of my 04.

Trannie cooler.



PS cooler

 

its PS. very common way for ford to cool the PS oil

 

take off that stupid pinch to release hose clamp and put a real one on there for starters.

 

How was removal of the bumper? I have an '06 - '08 bumper to put on after I get it painted but i'm not so sure how it will mount, though I have all mounting hardware.
