[DeTomaso] weird tiny coolant tube

[Joseph F. Byrd, Jr.]

There were two TSB attempting to vent the air in the coolant.  T
he first was adding a top of the radiator outlet vent back to the outlet
metal tube.
The next was to route the top of the radiator outlet back to the pressure
tank.   
IMO, the second TSB was an error.  the tank is at a higher pressure than the
radiator outlet, thus no venting.
I would prefer the first TSB vent. 
Even better venting would be to convert pressure tank to a true swirl and
the recovery tank to a surge.  Then route the upper radiator outlet to the
surge.

Joe

There was a Ford service bulletin that mentioned that line that you are
talking about. It was to vent air out of the radiator and it may have been
installed by the dealer. I don't believe that any of the early cars had that
installed from the factory. My March 1973 built car did not have that line,
but I am not sure about the cars built after mine.
