If in the same fairly close range to home situation I'd consider removing the fan/clutch and drive it home. That would prevent the possibility of the fan causing damage. As long as the D1 is moving it shouldn't over heat sans the fan. I've driven my D2 sans the fan/clutch in 40 dgree weather and never overheated. Still a slight risk the pump could grenade and some damage. No guts no glory or leave/tow.
