Installation Procedure


    Object Number: 161035  Size: SH

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

  1. Install the transaxle oil cooler hoses.
  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 clip bolt to the transaxle oil cooler hose.
  4. Tighten
    Tighten the clip bolt to 25 N·m (18 lb ft).


    Object Number: 161059  Size: SH
  5. Install the hoses to the transaxle oil cooler and/or the auxiliary transaxle oil cooler pipes at the radiator.
  6. Install the clamps to the hoses at the transaxle oil cooler and/or the auxiliary transaxle oil cooler pipes at the radiator.
  7. Install the hoses to the transaxle oil cooler fittings in the transaxle.
  8. Tighten
    Tighten the hose fittings to 23 N·m (17 lb ft).

  9. Lower the vehicle.
  10. Notice: Do NOT overfill the transaxle. The overfilling of the transaxle causes foaming, loss of fluid, shift complaints, and possible damage to the transaxle.

  11. Adjust the fluid level.
  12. Inspect for proper completion of the repairs.
  13. Inspect for fluid leaks.
