  1939 Ford hot water heater defrost nozzles, is there a difference in the nozzles for a closed car and the station wagon & convertible if so what is it and do you have a photo. I have attached a photo of a pair of nozzles from a closed car P/N 91A 18491-B. Thank you in advance for any help.

  The May 1, 1940 chassis parts catalog shows the same P/N for all 85 HP passenger cars. The A suffix part fits both 39 and 40, while the B suffix fits only the 39.

  I have a Ford Chassis parts book dated May 1941 and it shows a 91A 18491-A is for a hot air heater 38 & 39 and the 91A 18491-B is for a hot water heater 39 only 85 HP and 95 HP passenger. There is a 99A 18491-A hot air 95 HP 39 & 40, I have no clue how that would work on a 40 Ford or Mercury as the opening for the defrost nozzle on the 40 is about 1/3 the size of the 39. If anyone has a convert or wagon nozzle and can supply a photo or measurements it would be helpful, if there is such a part as it is not shown in the part books I have. Thanks

  Dave: Sorry I never got back to you since my 11/16/09 email as at the time I was trying to send you some Ford defroster nozzle photos. Have had no luck in downloading these from my card reader to the computer. I think one showed what I have identified as a 1939 Conv/Station Wagon nozzle. It is different than all the others and is a short and squatty looking thing.
If you will email me your address, I will mail some photos previously mentioned while making sure one shows the Conv. nozzle. Presume you already know my email address. I will also send a copy of the installation instructions for this defroster. The 1938-1939 Ford Book also shows this instruction sheet. I believe this nozzle carries P/N 91A-18491-C.

  cpipp01,

I put on my reading glasses and the 40 catalog shows the same information that you have. I have checked the 38-39 catalog from Jan 1939 and the 38-40 catalog from Oct 1939 and they show the same information.

I did not find and C suffix hot water heater defroster nozzles. The commercial vehicles used a different defroster nozzle 91C-18491 in 1939.

  A lot of information for 39-40 heaters and defrosters is in an article by the late Tom Cherry V8 Times July August 1989 "Heating up your Early V8 Fords" One paragraph quote " Dual defroster models of station wagons and open cars produced after 12/14/38 required special nozzles for hot air as well as for hot water and adapters were provided in the 91A=18444 conversion kit." I think this was necessary because of the location of the wiper towers on these models,cowl mounts.

  37, and everyone, that's a name that's worth an extra word or two. Tom Cherry Jr was absolutely the undisputed authority on Ford heaters. His son Tom III was into Ford heaters also, but after his father's passing, Tom moved on to muscle cars, and his knowledge is no longer available to us. The two of them, back then, did seminars, packing along with them examples of all the variations of Ford heaters. My Regional Group was very fortunate to have hosted them for one of their last seminars.

The loss of Tom and of countless others who, back in the day, were walking talking parts catalogs is hard to comprehend today, as we now must usually rely on research rather than first hand expertise for so many questions we have regarding our cars. This is not to say we've lost all our experts, but they are slipping quietly into history right before our eyes. We'll get along without them, as ignorance is bliss, they say, but the loss to us all in the hobby is incalculable.

The legacy of many of those experts is now contained in the Fords they restored, but their writings in the V8 Times is available to all of us now and in the future. One of the most valuable and underused benefits of our Club is the Index of Technical Articles in the annual Roster. The index alone consisting of 36 pages, the articles themselves and the collection of books they are contained in, unlike the men who wrote them, will continue to be there for us in the future.

  I have a little part of his legacy in my 39 hot water heater,I had the harness kit and a lot of other stuff and the memory of a few phone conversations with him. The 39 heater never got in to the project at the time but a couple years ago I dug out the correct and still good quart of brown paint I bought from Tom in 1990,finished restoring the heater and using the standard template drilling holes installed in my 37 coupe,not correct but looks good and keeps me warm when I need it,no defrosters.

  Tom was not only an authority on the heaters, he and his son reproduced the 39 and 40 heater switch knobs. Whenever I met Tom or his son at a swap meet, I got an education as well as a good hour or 2 of great conversation. He was a very friendly guy and knew a lot about the cars.
