Go to an auto parts store (I got one from NAPA) and ask for a shut-off valve for your heater system. It won't be factory, but it will fit into the heater hose that supplies your core. Screw down the valve and the water is shut off, and heat is, too.

It's what I did when my heater control valve (in the same hose) began to leak. It's vacuum controlled, so take a look under the hood, on the passenger inner fender....if it is there, you'll see it. It may have gone bad and been by-passed, too.
