Heater Control

[53lowdown]

I'm trying to figure out my 62 C10 heater controls for thrift heater. I only have two levers on the control. One for the fan switch, and one that pulls the cable to the heat/defrost flip door.

Doesn't there have to be a third lever for the valve to shut off the coolant circulation?

The control doesn't look like it has been hacked up, but there are only two levers.

Thanks

I don't think there is one.

I just went through the 1960 Recirculating Heater installation instructions and there was no shut off for the hot water. They didn't even suggest a mechanical valve on the hoses, just straight hook up from the engine to the heater. Must have been pretty uncomfortable in warm climates.

Here are the pages from the factory accessory manual:

Good info - thanks. Not much concern about too much heat right now! I guess in the summer I could just put a short loop of heater hose to bypass the heat exchanger.
