Can anyone tell me from looking at the pictures, what is leaking, and possibly from where? 2010 f150 5.4 3v.

 

Not really! I have the same model and same engine and I can't tell. Other than the left side of the radiator looks damp but without seeing it in person I can't tell if it's coolant of something else or even if that is really a leak. You need to take this to someone with some experience so that they can see it in person. You give far too little detail for anyone to make an accurate guess over the internet.

 

I believe The dampness that's seen in the pick, is on the AC condenser. The AC in the truck is working very well, so I don't think it's Freon. The radiator is right behind the condenser so I'm thinking it's either tranny fluid or maybe motor oil?

 

How would ether transmission fluid or motor oil, neither of which are naturally anywhere near that location, get onto the condenser?

 

Been looking online and it turns out, it's power steering fluid.
