Installation Procedure
- Using your thumb and forefinger, insert a NEW retaining clip into one of the three connector fitting recesses. Ensure that the retaining clip engages all three slots in the connector fittings. Failure to properly install the retaining clip could cause the cooler line to come loose and cause damage to the engine.
- With one end of the retaining clip engaged in the connector fitting slot, use your thumb to rotate the clip around the connector fittings, until the clip snaps into place.
- Do not install the new retaining clip onto the fitting by pushing down the clip.
- Ensure that the three retaining clip ears are seen from inside the fitting and that the retaining clip moves freely in the fitting slots.
- Install NEW retaining clips into the remaining quick connect fittings, if necessary.
- If equipped with a 6.5L engine, connect the oil cooler lines to the engine block fittings.
- If equipped with a 8.1L engine, connect the oil cooler lines to the engine block fittings.
- If equipped with a 8.1L engine, connect the oil cooler lines to the radiator fittings.
- Install the cooler line into the quick connect fitting until a click is either heard or felt.
- Do not use the plastic cap on the cooler line in order to install the cooler line into the fitting.
- Pull back sharply on the cooler line in order to ensure that the cooler line is fastened into the quick connect fitting.
- Position and snap the plastic cap onto the fitting. Do not manually depress the retaining clip when installing the plastic cap onto the quick connect fitting.
- Ensure that the plastic cap is fully seated against the fitting.
- Ensure that no gap is present between the cap and the fitting.
- 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.
- Do not install the cooler line end into the fitting incorrectly.
- If you cannot position the plastic cap against the fitting, remove the retaining ring from the quick connect fitting. 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 the oil cooler line.
- Install the cooler line into the quick connect fitting again in order to install the remaining cooler lines into the remaining quick connect fittings.
- If equipped with a 6.5L engine, install the cooler line fittings (2) to the oil cooler (1).
- Tighten the oil cooler lines.
- If equipped with a 6.5L engine, install the oil cooler line clip.
- If equipped with a 8.1L engine, install the oil cooler line clip.
- Check and add transmission fluid if needed.
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.
Tighten
Tighten the oil cooler line fittings to 24 N·m (18 lb ft).
