Location: Buffalo, NY | My frustration is with what's called the "Water Valve Fooler Element". A secondary capillary tube is essentially heated by a resistance coil that the manual says is wound around it. Here's a picture on page 455 of the 58 Plymouth service manual...
Now, not including the secondary capillary tube itself which is connected to the heater control valve this is what I have....
If you look closely you'll see that each wired end of the secondary capillary tube shield has what appears to be a tiny bit of white thread like wire? It appears to be broken although I don't know if this thread itself gets wrapped around the capillary tube as stated in the service manual or if I am missing the resistance coil itself? In the manual photo it appears to be inside the coiled capillary tube as opposed to being wrapped around it. I also suspect that the one wired end may have had the round electrical terminal added as I can't find anything in the manual as to where it would mount. I'm essentially stumped as I don't know what may be missing if anything and the best approach to correcting and/or repairing this. I don't have an electrical background and I am not an electrician. Can someone explain to me how this works exactly and if I may in fact be missing the resistance coil itself? Perhaps I could use something modern day in place of it? Any help here is much appreciated!

Location: Arizona | Can you tell from the manual what turns on the electric to that resistance thing? Is it on when the Fan is on or when the headlights are on or when you put the brakes on or ???? |

Location: Perth Australia | I havnt seen one before, but, from what I can see
The eye terminal will go under the mount of the heat shield
There should be a ceramic (most likely) or mica tube that the resistance wire wraps around (the white cotton looking stuff)
That wire is very simmilar to whats used in gauges ect
The bad thing is the wire is broken at the power end and cant really be succesfully joined (normally, its sandwiched under a rivet)
The other thing (and confirm I am right first) if its missing the tube, I have no idea where you would find one without getting a whole new assembly

When cooling is selected on the dash switch the resistance coil is activated. As you move the temperature lever to cooler, that action mechanically controls a rheostat that decreases/increases resistance to the fooler element "heater" as the heater control valve opens/closes. The heating of the secondary capillary tube "tricks" the primary tube thereby making the discharged air passing over it seem warmer than it actually is. The heater control valve then tends to close thus reducing the heating of the air shifting the temperature to the cooler desired level.
Still, I haven't had any luck determining exactly how the heating element is made. Ie...Ceramic etc. |
