Oil Cooler Hoses: Installation

NOTE: Allow sufficient clearance around the transaxle oil cooler pipes and around the hoses to prevent damage or wear which may cause fluid loss.

1. Install the TOC hoses to the vehicle. See Figure .
2. Connect the TOC hoses to the radiator support retainer.
NOTE: Failure to properly install the retaining clip could cause the cooler line to come loose and cause damage to vehicle components. DO NOT install the retaining clip onto the fitting by pushing on the clip.
3. Connect the TOC inlet hose to the radiator as follows:
   1. Install the retaining clip into the quick connect fitting by using your thumb and forefinger. Insert the retaining clip into one of the three fitting recesses. Ensure that the retaining clip is engaged in all 3 slots. See Fig 1 .
   2. With one end of the retaining clip engaged in the connector fitting slot, use your thumb in order to rotate the retaining clip around the connector fitting, until the retaining clip snaps into place.
   3. Ensure that the 3 retaining clip ears are seen from inside the fitting and that the retaining clip moves freely in the fitting slots.
      NOTE: A distinct snap should be heard when assembling the cooler line to the quick connect fitting. To ensure the cooler line is fully inserted into the quick connect fitting, give the cooler line a gentle pull. DO NOT use the plastic cap in order to install the cooler line into the fitting.
   4. Install the cooler line straight into the quick connect fitting until a click is either heard or felt.
   5. Pull back gently on the cooler line in order to ensure that the cooler line is installed in the quick connect fitting.
      NOTE: Ensure the cooler line being installed has a plastic cap on the end that connects to the quick connect fitting. If no plastic cap exists, or the plastic cap is damaged, obtain a new cap. Install the cap on to the cooler line prior to cooler line installation. DO NOT manually depress the retaining clip when installing the plastic cap.
   6. Snap the plastic cap onto the quick connect fitting.
   7. Ensure that the plastic cap is fully seated against the fitting.
   8. Ensure that no gap is present between the cap and the fitting.
   9. Run the engine. Inspect the transmission oil cooling system for leaks.
   10. Inspect the fluid levels. Add fluid if necessary.
4. Connect the TOC inlet hose to the transaxle. See Figure . Perform steps  A - J .
5. Connect the TOC outlet hose to the transaxle. See Figure . Perform steps  A - J .
6. Install the TOC hose retainer and the bolt. Tighten to specification. See TORQUE SPECIFICATIONS  .
7. Lower the vehicle.
8. Connect the TOC outlet hose to the top side of the radiator. Perform steps  A - J .
9. Adjust the fluid level. See LUBRICATION  .
