I wish to change the coolant in my 1990 740SE's [B200F] engine before the winter comes. I have changed the coolant on many cars over the last ten or so years, but have never done the job on a Volvo 700, but I imagine it to be dead easy. What really worries me, however, is that I have heard stories relating to the 700 series of the radiator bottom hose stubs breaking away from the radiator when the hose is removed to drain the coolant.

If this were to happen to mine, I would be in trouble as the car is an automatic and therefore has a transmission oil cooler built into the radiator, which means that replacing the radiator would involve lots of grief removing the oil cooler pipes from the radiator and the subsequent transmission oil loss/air in the fluid circuit itself, leading to extremely complicated (For me) bleeding of the system

Are my fears unfounded (Looking at the design of the radiator hose stubs, I cannot see how such a thing could happen) , or do the 700s' radiators frequently shed their hose stubs when the hoses are removed?
