Shutting off the heat

[timvasqz]

In my 94 pt the electric valve that closes the heat circulation path is normally
open. to close it requires 12 volts and consumes amp hours 24-7. What many call
a phantom load is simply that not realized. this valve was a phantom. One path
of engine coolant that can be kept functioning while the hear register path is
turned off is the water heater. that is why there are so many valves.

working properly you just have to turn your switch's off and you shouldn't get
any heated antifreeze to the heat exchangers. All it takes is a little debris in
the water valve and the diaphram won't close off the valve. On my PT40 with the
switch's off all the heat is off.

couldn't figure ours out either and used to roast up front all summer. I finally
realized that you have to shut off the 4 valves in the engine compartment to
completely turn the heat off. Otherwise, the hot coolant seems to keep
circulating- even with the summer/winter switch on summer and the front heat
dash switch off. It sounds like others have clued you into this as well.

switches on dash and panels above. But, we are still getting heat out of the
vents. I'm guessing it's coming from the chassis heating system since all the
others are off. Surely their must be a valve to shut off somewhere. . .
