Radiator hose ?

[rcl700]

I see radiator hoses for plymouth flatheads listed at $80. Can normal modern day hose be used in place of these? 

Seems like the small upper could just use a small section of heater hose. And the 3 lager sections cut from a piece of straight radiator hose for a fraction of the cost. What are these type of hoses pictured called? Or what type are they? They seem to be belted on the exterior.

 

Does anyone know the correct size needed if I were to make up my own?

These are regular radiator hoses, made to look like the ones produced in the past. Here are the sizes, for the 201/218 engine, from the manual:

Enjoy.

Many thanks. This is the information I was in need of. This group of plymouth enthusiasts is the best!

If you are also not looking to be period correct then you do not have to have the two wire hose clamps.  You could use the more modern hose clamp that has the opening in which the screws tightens the band and you can see the slots in the clamp.

 

If a driver then go this way but if you are going to want the car judged then you will have to used the two wire clamps to be correct.

I believe that those are called worm gear clamps. Virtually the most common clamps, these days. I personally, prefer the t-bolt or spring clamps, for some reason. Also, I believe that spring clamps are actually technologically superior because they supply constant pressure to the hose. But the early cars have an open cooling system, so it is not like you need a lot of force to hold the clamps in place.

 

Also, I've seen different types of clamps in different Chrysler illustrations from 1940-50. Some wire clamps had Philips screws, some had round slotted head. Once, saw a single wire spring clamp on the bypass hose ?

I was doing a search in my 1929-39 Desoto, Ply Master parts book and they used or documented that the hose clamps were a flat band style and the two wire clamps style was only used other by-pass rubber hose at the water pump. Then around 1942 they made a change to a different style clamp which is a flat band style. We can not find any examples of the newer style nor does anyone have any.  Most of the major clubs such as the Ply owners club and WPC all recognize the two wire style clamps as being the proper clamp.
