Air trapped in the system can cause premature failure on the pump, hard steering, fluid cavitation, and a whining pump. DO NOT drive the vehicle without bleeding the system as you do risk damaging the pump.
To test system pressure, leave the gauge valve open and have a helper turn the steering wheel full right and full left. At each position, the pressure with the valve open should be 76 to 82 bar (1102 to 1189 psi). If not, the steering gear should be replaced.
