Shutting off the heat

[Wayne Kotila]

Hi Shane:

If the water valves controlled by the 12 volt solenoids are not dirty and 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.

Hi Jerry,

Kelly and I had a good laugh this morning- at your expense of course- We 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.

chassis heating system since all the others are off. Surely their must be a valve to shut off somewhere. . .
