Hi
Pardon my ignorance, but .... I have a Saab 93 2L petrol 2011 and the power steering appears to be erratic.

I understand there are variations on the type of power steering - according to the Haynes manual - conventional ( engine driven ) or electro hydraulic ??

How can I determine which one - I has assumed there would be a reservoir for the fluid somewhere ??

Any guidance most welcome
