Installation Procedure


    Object Number: 161067  Size: SH

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

  1. Install the auxiliary transaxle oil cooler hose and pipe.
  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 auxiliary transaxle oil cooler hose and pipe fittings to the auxiliary transaxle oil cooler.
  4. Tighten
    Tighten the auxiliary transaxle oil cooler hose and pipe fittings to 23 N·m (17 lb ft).
