[DeTomaso] Techno Question: The Proper and Correct Way to connect the engine heater hoses to the central heater tubes

[cengles at cox.net]

Dear Julian,

                     I believe that your description of the hot water 
circulation of the heater core.  I looked at the Ford parts book and 
could not tell whether the correct tube was the right or the left.  My 
last visit the knuckle-busting territory of the heater valve was about 
twenty years ago when I rebuilt the valve and placed the double 
throw-down Gates heater hoses.  It should be connected in the stock 
manner.

                     That is the information I was looking for.  I will 
plan to check that the right heater tube hose goes to the engine block. 
Thanks!

                                           Warmest regards, Chuck Engles

  Chuck,

I believe the hot engine block (feed) should go to the heater control 
valve and the cooler return to the water pump. This would make sense to 
me for a number of reasons; a) be able to shut off the hot side prior to 
entry to the heater and prevent over pressuring  of the heater core and 
b) the water pump is a suction pump pulling the return and c) the heater 
valve is on the lower side of the heater core thus feed on this side 
allows air to be purged up and out with direction of flow.

The heater valve in diagrams is connected to the right hand tube, 
however in going to good effort to do all correctly it is worth 
verifying that the two short sections of hose under the driver kick 
panel are in good order and connected to the correct tube.

Dear Forum,





                       Yes, I am still wrestling with the heater hoses. 
In
years gone by, I simply connected them up willy-nilly.   So far, no
catastrophic heater core failure.  I recall seeing someone mention the
correct and proper way to connect the heater hoses from the water pump 
and
the engine block to the central heater tubes so that the hot water flow 
to
and from the heater core is correct.   I just reviewed the factory 
manuals
and Ford parts book without finding any answer.





                        So, does anyone know the answer to the mystery 
of
which way to connect the right and left central heater tubes to the 
engine
block and water pump hoses??





                                        Warmest regards,  Chuck Engles
