Saturn Repair Problems? Ask a Mechanic for Answers ASAP
Back in the day, it was "ok" to use transmission fluid for power steering fluid. These days... not so much. Best bet here is stick with a GM-spec Power Steering Fluid. This should be readily available at any local parts store.
As for adding fluid- remove the cap and pour the fluid right into the reservoir. On the stick attached to the cap, there are lines that will show where the correct level is full. Add some fluid then install the cap and check the level against the marks on the dipstick until the correct level is achieved.
