I assume Ford's famous use it up practice resulted in some 1915 cars having electric lights accompanied by acetylene tubes soldered across the radiators. In such cases, did they run the wire between the headlights through the tube?
Steve, I would think the ends of the tube would eventually cut through the insulation on the wire if you we're to route your headlight wiring that way.
Are there not two holes right by the tube. The wire would go in those holes. There would be a bigger tube for the wires to cross the rad. That tube does not look like a factory solder job. Did someone remove the wire tube and add that tube? Dan
I know nothing about the history of this thing. Yes, it's quite possible this tube is a home installation. Did the radiators on electric lighted cars have a tube between the two holes? If so, what size?
I would simply run the wire through the gas tube as you describe.
The radiator that you have with the tube is for 1913-1914.
I have seen some he 1915-1916 radiators with a straight tube for the wire and some with little "clips" along the support bar for the wire.

Tube specified for headlight wire across lower part of radiator. To be made of defective radiator tubes. Old tube for gas lamps is to be discontinued. Holes are added in side walls of radiator and this new tube is to be put in place by spreading the radiator fins and is to then be soldered in place.
From: http://mtfca.com/encyclo/P-R.htm#rad that says:
Spun-brass filler neck, riveted and soldered in place During 1914 the name plate on the back of the upper tank was eliminated and was replaced by embossing the design in the tank wall itself. In 1915 the gas tube for the lamps was eliminated. Filler cap had short fins. In 1915, too, the flanges of the side wall where they overlap the frame were made shorter. The embossing on the rear of the top tank was again changed and now indicated the month and year the radiator was manufactured.
Recommend you look on the back of the radiator and see if it has a tag, embossed, or embossed with a date.

This shows the engine wiring location for 15-18. There was a crossover tube but I thought they were more toward the bottom of the radiator. This diagram shows the tube to be much higher--Almost inline with the lights.
"During 1914 the name plate on the back of the upper tank was eliminated and was replaced by embossing the design in the tank wall itself."
That suggests this one came along sometime in 1914 after the change from tag to embossing.
[In 1915] "The embossing on the rear of the top tank was again changed and now indicated the month and year the radiator was manufactured." No date here, so apparently before that change. What strikes me as odd is "NO" followed by no number.
"In 1915, too, the flanges of the side wall where they overlap the frame were made shorter." Too bad the encyclopedia doesn't give measurements.
Based on all this, I'm guessing late 1914. That's close enough for me.
