Installation Procedure

    Object Number: 627406 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.

    Important: The correct thread engagement is critical. Crossthreaded fittings can achieve proper tightness and still leak.

  1. Apply sealant to the transaxle oil cooler fittings (28,29).
    2. • For green inlet cooler fitting GM P/N 8651654.
