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...

Joined: May 2005 Posts: 8,878 | You can get aftermarket valves that are cable operated and just fit inline with one heater hose. You can also get a heater valve that screws in the water pump and the heater hose connects to it. Check NAPA.
Either will be relatively cheap, effective, and easy to install.
