Installation Procedure

Important:  A distinct snap should be heard when assembling tube ends of the hose assembly to quick connectors. To ensure tube is fully inserted into the connector, check by giving tube a forceful pull.

1. If equipped with a 6.0L engine, perform the following:
   1. Install the oil cooler hose assembly and a new gasket.
      CAUTION: 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.
   2. Install the oil cooler hose adapter bolts (2).

      Tighten 

      Tighten the bolts to 12 N.m (106 in lbs).

   3. Install the oil cooler hose bracket bolt (1).

   Important: 

   • Ensure the oil cooler line being installed has a plastic cap on the end that connects to the quick connect fitting. If no plastic cap exists, or the plastic cap is damaged, obtain a new cap. Install the cap on to the cooler line prior to cooler line installation.
   • Do not use the plastic cap in order to install the cooler line into the fitting.
   • Connect the oil cooler lines. Refer to Engine Oil Cooler Pipe/Hose Quick Connect Fitting .
5. If equipped with a 8.1L engine, perform the following:
   1. Install the oil cooler hoses to the clip.
   2. Install the oil cooler lines to the radiator. Refer to Engine Oil Cooler Pipe/Hose Quick Connect Fitting .

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

   3. Pull back sharply on the cooler line in order to ensure that the cooler line is installed in the quick connect fitting.
