Ok ran the motorhome today had hot water going towards the front off the motor but no return.

Does this valve control the flow of hot water from the engine? The one that says inlet.

Sure looks like it could

Check it for delta temperature switched on and off

Different than mine but different rig as well

You might want to actually loosed the hose clamp and see if you have flow when the coil is energized and when it isn't with the engine running so you have a bit of psig

There is always a possibility of a kink in the return hose which I had to deal with. It was behind the generator and caused all kinds of issues
