John,

It can, and has been done.  Somewhere in my vast library of clippings 
from numerous T series club newsletters, I have an article on making 
such a modification.  If you are interested, I can send you a copy.  
That said, I agree with Bob, when he asks, "is it needed".  My answer 
would be no, it isn't.  As Bob points out the cooling system in the T 
series cars has an overly large radiator that doesn't need much external 
help.  About the only thing that pressurizing will help with is to 
increase the boiling point of the coolant (if I remember correctly, the 
boiling point is raised a degree or two for every pound of pressure).  
We have been driving out TD for over 25 years, all over the western US 
in all kinds of weather and have never had the cooling system boil on 
us.  Instead of pressurizing the system, if the time and money is spent 
in getting the cooling system in tip top shape (clean radiator and clean 
cooling passages in the engine,etc.and using a 25% - 50% solution of 
antifreeze) one will have a system that can handle anything that normal 
driving can throw at it.  The addition of a coolant recovery system is 
the one thing that I added to our TD.  While it doesn't do anything to 
prevent boiling, it does make keeping the coolant level where is should 
be much easier.  For information on how to install a coolant recovery 
system, see the article, Expansion Tanks, Coolant Systems and How the 
Cooling System Works in the Other Tech Articles section of my web site

Cheers,
Dave
