Reply to "electric heater control valve"

Gary,

How do you control your heater control valve?

There's a rad shop in Bellflower, CA that used to sell an electronic heater control valve kit that used the Thermotion bypass style valve. The kit contained an assembly that connected the stock COLD - HOT control lever to a slide potentiometer that, in turn, controlled the electronic heater control valve. They discontinued the kit a few years ago due to lack of demand. It's too bad because it's a very good idea moving the heater control valve out of the passenger compartment. Once you've done that, neither of the heater hoses are under pressure when the heater control valve is in the "COLD" position.

I purchased one of these kits years ago but rather than install the valve in the engine compartment, I mounted it to the front bulkhead, just above the main coolant pipes (just behind the steering rack). Since then, I've moved away from the bypass style (four port) heater control valve and installed a two port (in/out) valve.
