It would help to know which model Kenworth you have. The cooling system pressure shouldn't be more than 15 psi. On later years of the T600, the T660, the T680, some models of the T800, and some models of the W900, the radiator has two caps.. the first is the fill cap, and the second has a bung, and that is the pressure relief cap. If the pressure relief cap is faulty, it usually fails to hold pressure, although it can fail to release pressure, particularly if there is blockage in the bung itself.
On Kenworth trucks which don't have this, the fill cap does double duty as the pressure relief cap.
I would check those first.
Defective cap? Bad thermostat building excessive pressure
Low coolant? Bad thermostat? Water pump not circulating coolant? Defective radiator cap not building proper pressure?
When vehicle is running: Water pump is circulating coolant and cooling system pressure is building
Heat will flow from the coolant to the air The coolant will absorb the heat from the building.

A coolant pressure test is used to detect a leak on the coolant system.
Have the coolant system pressure tested, the pressure test will increase the coolant leak.
No, the oil level can affect the the oil pressure if it is too high or low. The coolant level has no connection with the engine oil pressure.
Kenworth was created in 1923.
It will be mounted to a pressure port on the service (foot) brake valve
Kenworth, without a doubt.
