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

[Julian Kift]

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
