Back in the day, you could put a pair of vice grips over the hose, just before the heater valve, and pinch it shut. Should still work with newer vehicles, since the valve, when closed, just stops the fluid there, anyway. Not the correct fix, but stuff like that can help you get home. If you pinched one side of the valve and coolant comes out, it's the wrong side, of course. We used to put boiler cutoff valves on the heater line to make sure no hot water snuck past the cable operated heater cutoff to our air conditioning on those hot Georgia summers.
