Is this the 616 with 40mm rad hose that you replaced last week instead of paying the stealer for OE hose? Buy the china hose to see if it works, then buy the OE hose to make it work properly? Cauldron sounds at startup and no cabin heat - that can't be. I doubt head compromise or water passage blockage - except at some gasket point, i.e. perhaps head gasket has water passage that is blocked and is passing combustion gas to the cooling system? Can you get the off-gas tested for combustion gas? Combustion gas would certainly heat the coolant. mao
