So a small update.
I actually got no clue, but when I run the pump and completly fill my resevoir, close the lid and shut off the pump a big amount of fluid squirts out of the 16 PSI valve cap.
My callaway supercharger sits higher than the resevoir.
So if the pump turns off, fluid drains into the resevoir + with higher flow because of the pump which actually triggers the overpressure valve.

I can't really tell, if the valve is maybe broken or not.
With HPTuners I could not notice a real difference in temperatures of the MAT.
Maybe it can't because it's not meassured, only calculated by the ECM as far as I know.
I still run high amount of glykol which directs heat worse.
