Power Steering Fluid Reservoir Replacement - Off Vehicle Remote

Removal Procedure


    Object Number: 247464  Size: SH

    Notice: Avoid contaminating the power steering system. Cap open hoses and ports to prevent dirt and debris from entering system. Contaminated power steering fluid and dirt can cause early parts failure.

    Important: Cap the hoses to prevent dirt from entering the system.

  1. Place a container under the power steering reservoir hoses.
  2. Clean the surfaces of the power steering reservoir hoses.
  3. Disconnect the power steering reservoir hoses.
  4. Allow the reservoir to drain.
  5. Remove the reservoir.

Installation Procedure


    Object Number: 247464  Size: SH
  1. Position the reservoir on the vehicle dash and toe panel.
  2. 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.

  3. Install the following components:
  4. • The bracket bolts
    • The hose clamps
    • The hose sleeve
    • The hoses

    Tighten

       • 

    Tighten the reservoir mounting nut to 27 N·m (20 lb ft).

       • 

    Tighten the hose clamp to 3 N·m (27 lb in).

  5. Fill the system with new power steering fluid.
  6. Bleed the system. Refer to Power Steering System Bleeding .
