Installation Procedure


    Object Number: 293138  Size: MH
  1. Hand-start the power steering gear inlet hose connection to the pump (1).
  2. Install the lower bolt (3).
  3. Hand tighten the lower bolt (3).

    Important: Provide a clearance of 2-5 mm (0.080-0.200 in) between the hose and the heater pipes. Contact may cause noise after the installation.

  5. 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.

    Important: Route the hose outboard and to the following places:

       • Under the engine harness
       • Under the heater hoses
