Re: All about heaters.

Not sure if it was answered here, but the motor for the heater has only one post for electrical connection. I presume this is (+) and the motor is grounded through the frame? Or is there a separate ground wire?

Re: All about heaters.

I am putting the recirculating heater back in my 62 and I was wondering if the hot water circulates all the time heating the cab in the summer? I didn't see any bypass valve when I took it out. The heater hoses were disconnected when I got the truck so I am not sure if I have all the parts.

Unless you have a valve to turn the flow off, it will run all the time. On my truck, I had some old valve that was cable actuated with the deluxe heater controls, but I have the recirc heater. It leaked and I couldn't find a replacement, so I put a manual valve in place. After leaving the valve on several times in the summer, I decided to replace the manual valve with a cable actuated valve. It's a metal valve from a 60s F100, but it works well and I don't have to pop the hood to turn the flow on or off. So much nicer that way


Edit to add pics. First is the Ferd valve, second is the controls. The air knob doesn't do anything but sit there and look nice

So you just need one? It doesn't need to circulate?

Re: All about heaters.

It's never been a problem. At first I was concerned about which side of the heater to put it on. You know, like perhaps I would be over pressurizing the core or whatever, so I googled it "nine ways 'till Sunday" and came up with no concrete case of anyone harming their heater core by putting a shut off on one side vs. the other. Ten summers later and still good.

Re: All about heaters.

If you do what I did, be cautious about what kind of fitting you thread into your water pump. Pipe nipples are tapered and there's not a lot of metal around the threaded socket of the water pump. Too much torque on the threads can crack the pump as you drive the expanding thread size into the socket. I did use a pipe nipple and teflon tape, but would have preferred an automotive nipple with a uniform thread diameter. Its just that my usual parts store didnt have it in stock when I wanted it, and the pipe nipple was already in my plumbing junk bin. The valve is simply a bronze ball vave rated for water/steam pressure.
