Do you have a repair manual for the Engine? That is where I would start looking for the Radiator Pressure and Cap.
I have an '82 with Detroit 6V92 in it. I am going to add a Recovery Bottle but plan to use the old Radiator Cap. The idea here is that when you increase the pressure at the Radiator Cap, it increase the boiling point of the coolant. I did a Google search and it looks like 15 psi raises the boliling point by 45 degrees. I am not recommending 15 psi, just some of the info from my search. With our older Diesel Engines we need to be careful and not raise the Pressure by too much otherwise you can make other problems with Head Gaskets, Head Bolts, etc.
I would check with the Engine Manufacturer and go with their recommendations.
Looking forward to what you find out.
