For 1990-2009 cars

Notice: If the power steering system has been serviced, an accurate fluid level reading cannot be obtained unless air is bled from the steering system. The air in the fluid may cause pump cavitation noise and may cause pump damage over a period of time.

Notice: When adding fluid or making a complete fluid change, always use the proper power steering fluid. Failure to use the proper fluid will cause hose and seal damage and fluid leaks.

1. Verify the vehicle is on a level surface.
2. Inspect for the power steering fluid in the reservoir (6) for foaming or a milky appearance. Foaming and a milky appearance indicate either the existence of air in the system or the fluid level is too low.

If the power steering fluid is foaming or has a milky appearance, bleed the power steering system. Refer to Power Steering System Bleeding .

3. Inspect the fluid level in the reservoir (6).
4. If the fluid level is below the MIN indicator (3), add Dexron®-III Automatic Transmission Fluid, GM P/N 12346143, or the equivalent.
