It would be nice to see a flow diagram of the engine, we know that it goes into the aqua Hot and back out again but where does it end up in the engine on the input of the radiator or back into the block of the engine. I know it might sound crazy but you might get a radiator hose clamp and back at the aqua Hot clamp off the in or the out back to the engine.

I can shut off the lines to the AquaHot and Dash Heat.  Currently the dash heat is off. I can try the AH as well. 

I’ll trace the return lines, it’s an interesting question. I believe they return to the block but I don’t know for sure. The compound turbo really makes it tight back there and it’s difficult to follow hoses and lines.
