Hi. My dad has a 1993 Ford F250 (7.5L V8) workhorse, and today a metal coolant elbow cracked and started leaking. He had to get home so he put some putty to slow the leaking. I am having trouble finding the part number to replace the fitting. It looks like it connects to the intake manifold right below the thermostat housing. If anyone could help me with a name or part number or even link for this part, that would be much appreciated. I'll upload a picture of the fitting in question.

 

I believe that fitting screws into the manifold.
If I recall correctly , those fittings are easily available from places like NAPA or dealership., usually 1/2 in pipe thread. Make sure before attempting to remove..
If the fitting is so corroded that it is itself leaking,lets hope it can be removed without breaking off.

 

You might want to consider inspecting or changing out the bypass hose/fittings next to in the image. They’re light pressed into the water pump and manifold. They’re thin metal, and can rust out fairly easy. More so, if the elbow has shown signs of leakage, I’d be suspect of them as well..
