Tools Required

J 36660-A Torque Angle Meter


    Object Number: 54362 Size: SH

    Notice: This component uses torque-to-yield bolts. When servicing this component do not reuse the bolts, New torque-to-yield bolts must be installed. Reusing used torque-to-yield bolts will not provide proper bolt torque and clamp load. Failure to install NEW torque-to-yield bolts may lead to engine damage.

    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 NEW cylinder head bolts.

    4. Tighten
    Tighten the NEW cylinder head bolts to 60 N·m (44 lb ft) in the order shown. Use the J 36660-A in order to rotate the cylinder head bolts an additional 95 degrees.
