2008 Cadillac DTS Automatic Transmission Oil Cooler Line Connector

You should not reuse any of the existing oil lines or oil line fittings if there is excessive corrosion, or reuse any of the existing retaining rings that were removed from the existing quick-connect fittings. Install new retaining rings.

You will need to pull the plastic cap back from the quick connect fitting and down along the cooler line about 5 cm (2 in), pull on one of the open ends of the retaining ring to rotate the retaining ring around the quick connect fitting until the retaining ring is out of position and can be completely removed using a bent-tip screwdriver, remove the retaining ring from the quick connect fitting, discard the retaining ring and pull the cooler line straight out from the quick connect fitting.
