If the water circulate properly that pipe with the red circle should also be hot.I am a bit confuse because you said the pipe is cold but in the beginning of your thread you said it is warm.Or do i miss something?
Where the water goes in it is hot, there by the valve. It's hot before the valve, and after the valve between the valve and the firewall. So the warm water is there and it goes throught the valve.
But where it comes back out of the firewall, there where I circled in red, it is cold.

I put in a cheap VW Valve that is open and working

Don't you mean if I CAN blow through, then it's the radiator?
