Re: 1955 Fleetwin, running hot?

[shoestringmariner]

Diameters appear to be 0.440" and 0.825"
I hope my local auto parts store stocks a variety of these sizes. Guess I’ll find out tomorrow

I had a look at the port on the cylinder head, I really don’t think water was coming out of there yet it is wide open. To me it looks like it has been dry for a while, but my experience is limited. This makes me concerned though, because if it was indeed wide open, and no water coming out, wouldn’t that indicate there’s a blockage in the cylinder head? Or purposely blocked for some reason?
