Oil Cooler Lines: Installation

NOTE: Do not reuse any of the existing oil lines or oil line fittings if there is excessive corrosion. Do not reuse any of the existing retaining rings that were removed from the existing quick connect fittings. All retaining rings being installed must be new. Ensure the following procedures are performed when installing the new retaining rings onto the fittings.

Install the transmission oil cooler lines to the vehicle.
Install a NEW retaining ring (E-clip) into the quick connect fitting using the following procedure.
Hook one of the open ends of the retaining ring in one of the slots in the quick connect fitting. See Fig 6. Rotate the retaining ring around the fitting until the retaining ring is positioned with all three ears through the 3 slots on the fitting. See Fig 7.
Do not install the new retaining ring onto the fitting by pushing the retaining ring. See Fig 8. Ensure the 3 retaining ring ears are seen from inside the fitting and that the retaining ring moves freely in the fitting slots. See Fig 9. Install the NEW retaining ring (E-clip) into the remaining quick connect fittings.

NOTE: Ensure the cooler line being installed has a plastic cap on each end that connects to a quick connect fitting. If no plastic cap exists, or the plastic cap is damaged, obtain a new plastic cap and position on to the cooler line prior to the cooler line installation.

Install the cooler lines to the vehicle. See Fig 2. Install the cooler line into the quick connect fitting. Insert the cooler line end into the quick connect fitting until a click is either heard or felt. See Fig 10.
Do not use the plastic cap on the cooler line in order to install the cooler line into the fitting. See Fig 11. Pull back sharply on the cooler line in order to ensure the cooler line is fastened into the quick connect fitting. Position (snap) the plastic cap onto the fitting. See Fig 12.
Do not manually depress the retaining ring when installing the plastic cap onto the quick connect fitting. Ensure the plastic cap is fully seated against the fitting. See Fig 12.
Ensure no gap is present between the cap and the fitting. See Fig 13. Ensure the Yellow identification band on the tube is hidden within the quick connect fitting. A hidden Yellow identification band indicates proper joint seating. See Fig 12. Install all remaining cooling line ends to the remaining fittings.
Install the transfer case vent hose, if equipped. Raise the transmission into position. Install the exhaust crossover pipe and the transmission support assembly. Remove the transmission jack.
On 4.3L models, install the stud and clip securing the cooler line to the engine. Tighten the stud to specification. See TORQUE SPECIFICATIONS .
On 2.2L models, Install the nut securing the oil cooler lines to the engine. Tighten the nut to specification. See TORQUE SPECIFICATIONS .
On all models, lower the vehicle. Fill transmission with appropriate fluid to proper level. See LUBRICATION .
