2007 F150 coolant leaking, do not know the part name

Hello, I have a bad picture here but I need help finding out what this piece is called so I can replace it. It's leaking coolant and it is near the rear of the engine (under the hood). It has three hoses attached to it. I do not believe it's the thermostat housing


If the picture is to hard to depict from I can take better ones tomorrow morning
Thanks for your time

It would've been nice if you would've moved the conduit loom out of the way.

It appears to be a coolant T adapter.

That's the PCV heater. Runs coolant thru it to keep the oil from solidifying in freezing temps.

For the life of me I cannot find a part #.

If it was my truck, I'd delete it, and put a barbed connector on it, and then find a fitting for the PCV to the intake manifold.

Never quite understood what the purpose behind it was other than emissions in very cold weather.

I don't think so - the optional heated PCV system on a 07 4.6 is electric, not coolant from what I can find.

That was my first reaction... I notice there isn't any wiring going to it.

But that is the PCV hose to the valve on the crankcase.

Odd. I'd love to know what the part # and Ford's description of that part is.
