Power Steering Fluid Amount?

The owners manual only has type, not volume. How much do I need for a complete flush?

 

I used ~2 quarts. Did a flush under power, not a turkey baster “flush”.

 

Engine running and turned wheels side to side till no more old fluid?

 

Simultaneously adding new fluid. Running the system dry can damage the pump.

 

I only used one quart. Then I removed some and put in some Lucas steering rack conditioner
