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.

 

Also, which engine?

 

Its the 4.6
Here are some better pictures

 

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.

 

Part number: 7L3Z-9A474-A

 

Where were you 8 years ago?

 

nearly dead.

 

curious, when did the 4.6 go to a composite manifold? my 04 has an all-aluminum upper manifold
