Otherwise, add oil. Use only Dexron-II fluid.
Fill only with new fluid, as even minor contamination in the fluid can lead to malfunctions in the power steering.
After filling the system with oil, turn the steering wheel from lock to lock several times with the engine running. This will remove air from the system.
Check the system for leaks.
