Hello!

When the previous owner put the heater back in my '53 Chevy 3100, he just ran a hose to it from the engine block, so there's coolant circulating through it all the time. Gets kinda hot in the summer.

From what I understand, there should be a diverter valve that mounts on the inside of the firewall.

Is that the case? If so, is anyone making them.

Also, how do you control the valve? Is there some wire-operated control?

Thanks...

Chris
