1. Pull the plastic cap back along the pipe in order to remove the plastic cap from the connector fitting.
2. Use a small, pick-type tool or screwdriver in order to release one of the open ends of the retaining clip from the connector fitting.



3. Rotate the retaining clip out of position on the connector fitting and remove the clip.
4. Discard the retaining clip.



5. Remove the oil cooler inlet and outlet hose clamp bolt.
6. Remove the inlet and outlet hoses from the clamp.

1. Using your thumb and forefinger, insert a new retaining clip into 1 of the 3 connector fitting recesses. Ensure that the retaining clip engages all 3 slots in the connector fittings. Failure to properly install the retaining clip could cause the cooler lines to come loose and cause damage to the engine.



2. With one end of the retaining clip engaged in the connector fitting slot, use your thumb to rotate the retaining clip around the connector fittings, until the clip snaps into place.



3. Do not install the new retaining clip onto the fitting by pushing down the clip.



4. Ensure that the three retaining clip ears are seen from inside the fitting and that the retaining clip moves freely in the fitting slots.
5. Install NEW retaining clips into the remaining quick connect fittings, if necessary.



6. Install the oil cooler lines to the engine block fittings.



7. Insert the cooler line end into the quick connect fitting until a click is either heard or felt.



8. DO NOT use the plastic cap on the cooler line in order to install the cooler line into the fitting.
9. Pull back sharply on the cooler line in order to ensure that the cooler line is fastened into the quick connect fitting.



10. Position and snap the plastic cap onto the fitting. Do not manually depress the retaining ring when installing the plastic cap onto the quick connect fitting.
11. Ensure that the plastic cap is fully seated against the fitting.



12. Ensure that no gap is present between the cap and the fitting.



13. Ensure that the yellow identification band on the tube is hidden within the quick connect fitting. A hidden yellow identification band indicates proper joint seating.



14. Do not install the cooler line end into the fitting incorrectly.
15. If you cannot position the plastic cap against the fitting, remove the retaining clip from the quick connect fitting per Step 3 of the cooler line removal procedure. Inspect the retaining clip and the tube end in order to ensure neither is bent. Replace the cooler line or the retaining clip if necessary, and reinstall per Step 2 of the cooler line installation procedure.
16. Install the cooler line into the quick connect fitting again in order to install the remaining cooler lines into the remaining quick connect fittings.
17. Install the inlet and outlet pipes to the retainer.

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.
