Re: It's getting toasty in here! ('41 Packard 110 Heater stuck on)

These are simple water valves. Perhaps the best thing to do would be to drain the coolant and replace the valve. You may find you can clean up the old one and get it operating again. I would just go down to a good auto supply store (NAPA, O'Rilley's, etc.) and buy a new one. Generally they were turned on in the winter and turned off for the warmer seasons. I leave mine cracked just slightly to allow for some water flow through the heater core all the time. Most folks do not do this, it is a personal preference.

Just had a thought: Is there a lock nut on the stem of the valve? If so, loosen the lock nut and you may be able to turn the stem to close the valve.

Good luck and enjoy the holiday!
