Lower Radiator Hose Block Heaters
Park the car in a heated garage.
Spray lots of WD 40 around the plug over a couple of weeks and wait until the liquid seeps in.
Do freeze plugs break off?

I remember hose heaters from when I lived in New Hampshire in the 1960's , they worked fine and I am glad to see yours does too.
Plus , having right - away heat is nice too !
I recommend a Eberspächer heater with a burner and waterpump, it heats the coolant and also controls the interior fan so that the cabin is defrosted and warm. It just cost about twice as much as a 83 240D.
I built a garage instead.
