Frank,
That theory is out there. Let’s start simple. Standing at the open hatch, staring at the rear of the engine, you will see the lines to the pump motor going through a aluminum block at the lower left of the engine. There is an electrical connection to the solenoid on the side of the block. Unplug the connection and start the engine. The fan should come on at maximum speed. It will be a hurricane. That will tell you if the hydraulic pump is working. As stated earlier, the fail safe mode on the fan solenoid is wide open, so when you unplug the solenoid, you get max fan speed.
When you say lost power steering, can you provide more details on what is happening. Does the steering gear box make any noise at all when you turn the wheel with the engine running? What was the circumstances when the PS went away? Just looking for clues to try to help.
