How many quarts or litres does the complete system hold ?

I tried to find the right answer to you but it depends on suspension options are built into your car. Anyway you have a maximum level on the reservoar . It takes some time to bleed the system out . I have seen on your other post that you tried to flush system. It takes much more fluid that actually your system holds. I would try to flush it with least 6 liter of fluid.P/S pump is pumping fluid really fast. Shops are have P/S fluid flush machine. They less messy as you would try it home.
