Need HELP ASAP on Tri-Pac coolant line plumbing...

[Waterloo]

Now I am not so sure the lines were reversed! No overhead today! Having a fit with this thing... Outlet (thermostat side) from Tri-Pac is fed into the inlet at the back side of the water pump on the ISX. I am assuming this is correct?

The radiator inlet side on the Tri-Pac feeds into a line that goes all the way over the top of the motor to the back side of the engine block... Does this sound correct?

Now the issue, I started the Tri-Pac, and thought I had her bled, I guess I did not. She shut down and through the ENG code... I drained the coolant out of the thermostat side, line is closed. Then I bled using the petcock, well a bit came out and then nothing. Nothing is coming out of the petcock on an open line. I wish it were Monday, as I would just call the dealer...
