1.What empirical method have you used to determine Unwanted/Out of Specs
Coolant Tank Pressures???
(Keeping in mind NOP [Normal Operating Pressures] are Approximately 1 Bar 14.5 PSI)
[I'd use the below HF Rad Pressure tester on the Coolant Tank(NO PUMPING)
to get an accurate reading on Cooling System pressures "At Rest" and
"Running"]
(Or any other way of introducing a Pressure Gauge into the System)
(The "Shadetree" symptom is "Hard" Radiator Hoses the Next A.M. without
engine operation.)[And you can Guess how much I'd trust THAT Idea...]
