To install:

NOTE
If not secured within 4 minutes, the sealant must be removed and the sealing area cleaned. To clean the sealing area, use silicone gasket remover and metal surface prep. Follow the directions on the packaging. Failure to follow this procedure can cause future oil leakage.

  1. Apply silicone gasket and sealant to the Woodruff key slot on the crankshaft pulley.
  2. Using the special tool, install the crankshaft pulley.
  3. Using a new crankshaft pulley bolt, install the crankshaft pulley bolt and washer. Using the special tool to hold the crankshaft pulley, tighten the bolt in 4 stages:

    Stage 1: Tighten the bolt to 90 Nm (66 ft. lbs.).
    Stage 2: Loosen the bolt one full turn.
    Stage 3: Tighten the bolt to 50 Nm (37 ft. lbs.).
    Stage 4: Tighten the bolt an additional 90 degrees without exceeding 200 Nm (148 ft. lbs.).
  4. Rotate the tensioner clockwise and install the drive belt.
  5. Install the cooling fan shroud.
6.0L Diesel Engine
All vehicles:
  1. Raise and safely support the vehicle.
  2. Disconnect the battery LH and RH ground cable(s).
  3. Remove the cooling fan stator. For additional information, refer to Cooling Fan Stator in this section.

  2. Check the crankshaft vibration damper runout.
    1. Remove the paint from the face of the crankshaft vibration damper at four points 90 degrees apart.
    2. Attach the special tool to the cylinder block. Position the special tool on one of the unpainted surfaces.
    3. Using a suitable tool, pry the crankshaft forward. Zero the dial indicator.
      NOTE
      Pry the crankshaft forward only to eliminate possible error caused by crankshaft end play.
  3. Rotate the crankshaft 90 degrees. Pry the crankshaft forward. Record the measurement. Repeat at each unpainted surface. If the runout exceeds specification, install a new crankshaft vibration damper.
    CAUTION
    To avoid personal injury, support the vibration damper during mounting bolt removal. The damper can slide off the nose of the crankshaft very easily.
  4. Remove the bolts and the crankshaft vibration damper. Discard the bolts.
To install:
All vehicles:

WARNING
To prevent engine damage, you must always install four new bolts when installing the vibration damper.


NOTE
Do not use anti-seize compounds, grease or any lubricants. Lubricants have an adverse effect on the torque results.
