4. Do not install the new E-clip onto the fitting by pushing the clip straight down.
5. Ensure that the three retaining ring ears are seen from inside the fitting and that the retaining ring moves freely in the fitting slots.





6. Do not use the plastic cap on the cooler line in order to install the cooler line into the fitting.





Notice: Ensure that 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.

Important: If you cannot position the plastic cap against the fitting, remove the retaining ring from the quick connect fitting per Step 5 of the cooler line removal procedure. Check the retaining ring and the tube end in order to ensure neither is bent. Replace the cooler line or the retaining ring if necessary, and reinstall per Step 2 of the cooler line installation procedure.
