Installation Procedure


    Object Number: 161063  Size: SH
  1. Install the auxiliary transaxle oil cooler.
  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 bolts to the upper radiator support.
  4. Tighten
    Tighten the auxiliary transaxle oil cooler bolts to 25 N·m (18 lb ft).

  6. Tighten
    Tighten the auxiliary transaxle oil cooler nuts to 10 N·m (97 lb in).

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