Installation Procedure

    Object Number: 167718 Size: SH

    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.

  1. Connect the cooling fan (3) to the fan clutch (4). Secure with the four washers and nuts.

    2. Tighten
    Tighten the cooling fan nuts to 11 N·m (97 lb in).

    Important: The fan clutch, cooling fan and shroud must be installed together because of insufficient clearance to install these parts in separate steps.

  2. Install the fan clutch (4), cooling fan (3) and shroud. Secure the components with the four fan clutch nuts and four shroud bolts.

    3. Tighten

        • Tighten the fan clutch nuts to 11 N·m (97 lb in).
        • Tighten the shroud bolts to 11 N·m (97 lb in).
