GM Service Manual Online
For 1990-2009 cars only

Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

Perform the following procedure to help identify the exact location of the leak:

  1. Turn the engine OFF.
  2. Wipe dry all the power steering system components.
  3. Wipe dry all the power steering system connections.
  4. Check the fluid reservoir.
  5. Add fluid if required. Refer to Checking and Adding Power Steering Fluid .
  6. The power steering system must be bled if the reservoir is empty. Refer to Power Steering System Bleeding .
  7. Start the engine.
  8. Have an assistant turn the steering wheel from stop to stop several times while you search for leaks. Do not hold it at a stop for any length of time or damage to the pump may occur.
  9. Find the exact location of the leak.
  10. Repair the leak as necessary.
