Fill the power steering pump reservoir with a good quality power steering fluid or Automatic Transmission Fluid (ATF) Type F .
See Figures 1 and 2
Position the vehicle on level ground. Run the engine until the fluid is at normal operating temperature. Turn the steering wheel all the way to the left and right several times. Position the wheels in the straight ahead position, then shut off the engine. Check the level in the reservoir; it should be at the FULL mark. If fluid is required, remove the cap and add fluid until it reaches the FULL mark.
