I need some help with figuring out my cooling problems.

 

Just so it doesn’t get lost in the following BS, I need to state that I think the problem is related to the coolant pressure.  It seems to me to be way too high.  I am beginning to think that the coolant is somehow partially blocked.

 

There is the pressure due to the expansion of the liquid governed by the cap, and the dynamic head, or difference between the intake and outlet of the pump, and flow restrictions in the system, which goes up and down with pump RPM.

 

This pressure difference changes with RPM, air content of the coolant, temperature of the coolant, and formula of the coolant. All normal stuff.
