Have you read the thread entitled "automarshal 3800sc"? That's the way I plugged the water pump and threaded a fitting in the lim heater port. The return port would be incorporated into a hose that's provides for the secondary smaller hose to join it. I haven't found that hose yet but I'm not up to that yet either. Dan (FIEROFLYER) , can you chime in here as I need that hose info. And the info to put a "t" fill on the other main coolant hose.
