Coolant pressure

[Porterave]

Is there a coolant pressure sensor on 2016 Freightliner Cascadia DD15?
There is this fan symbol on the dash that reads between 8-20psi. It is 0 psi now because truck is turned off. Is this the coolant pressure?
The truck had this coolant leak on the hose going to the radiator. The clamp was a little loose so we tightened that and are monitoring it.

That would be your turbo boost pressure.
