  1. Ensure that the camshaft sealing rings (1) are in place in the camshaft grooves. Camshaft sealing rings must be in place below the surface of the camshaft journal in order to avoid being pinched between the cylinder head and the camshaft caps.

    2. Object ID: 2893766
  2. Apply a liberal amount of lubricant (1) to the camshaft journals and the right cylinder head camshaft carriers. Refer to Adhesives, Fluids, Lubricants, and Sealers for recommended lubricant.

    3. Object ID: 2893769
  3. Place the right intake (1) and right exhaust (2) camshafts in position in the right cylinder head (3).

    4. Object ID: 1306310
  4. Position the camshaft lobes in a neutral position with the flats on the back of the camshafts up and parallel (1) with the right cylinder head camshaft cover rail.

    5. Object ID: 2537351
  5. Observe the markings on the right cylinder head camshaft bearing caps. Each bearing cap is marked in order to identify its location. The markings have the following meanings:
    • The raised feature (1) must always be oriented toward the center of the cylinder head.

    • The E indicates the exhaust camshaft.
    • The number 1, 3, 5 indicates the cylinder position from the front of the engine.
  6. Apply a liberal amount of lubricant to the camshaft bearing caps. Refer to Adhesives, Fluids, Lubricants, and Sealers for recommended lubricant.

    7. Object ID: 2537341
  7. Apply a liberal amount of lubricant to the camshaft bearing cap (1) and camshaft thrust surface (2). Refer to Adhesives, Fluids, Lubricants, and Sealers for recommended lubricant.

    8. Object ID: 2537353
  8. Install the camshaft bearing thrust caps (1) in the first journal of the right cylinder head.
  9. Install the remaining bearing caps (2) with their orientation mark toward the center of the cylinder head.
  10. Hand start all the camshaft bearing cap bolts.

    Caution: Refer to Fastener Caution.

    Caution: This vehicle is equipped with torque-to-yield or single use fasteners. Install a NEW torque-to-yield or single use fastener when installing this component. Failure to replace the torque-to-yield or single use fastener could cause damage to the vehicle or component.

  11. Tighten the camshaft bearing cap bolts in the sequence shown and tighten to 10 N·m (89 lb in).
  12. Loosen the center intake camshaft bearing cap bolts (1, 2) and the center exhaust camshaft bearing cap bolts (3, 4).
  13. Retighten the center camshaft bearing cap bolts (1, 2, 3, 4) and retighten the camshaft bearing cap bolts to 10 N·m (89 lb in).
  14. Install the camshaft position actuators. Refer to Camshaft Position Actuator Replacement - Bank 1 .
