Re: [FWDLK] why so many heater hoses



 
On a 1955 Dodge (Plymouth, DeSoto, Chrysler and Imperial) there is a heater hose that runs from the engine through the firewall to the heater temperature control valve assembly.  A second hose runs from the outlet of the valve assembly, back through the firewall to the lower inlet on the heater core.  Finally, a third hose runs from the upper outlet on the heater core to the engine,
 
If either, or both, the valve asembly or the heater core is faulty, someone has run a hose to bypass them.   If the heater core has gone, the coolant will be leaking.  If the valve assembly has died, it was bypassed to prevent a constant blast of heat.  Which would account for the fourth hose.
 
The heater core probably can be recored, as least if the the frame and outlets are still in good shape.  Any good rad shop can do that. 
 
If the control valve is gone, some have replace it with an inline valve from a plumbing shop, similar to the one found on the water supply pipe to a toilet.  Controlling the heat temperature would be a little inconvenient, but it would work until you found a new control valve.    Just make sure you get the correct pipe diameter to match the heater hoses.

I noticed on my ?55Dodge (new to me) that the heater core is disconnected and the hose on the engine talking to itself.

 

I also noticed that it appears there are 4 hoses involved in what I would have thought to be a two water line hose operatioin.  What am I looking at?  TIA
