CAMSHAFT POSITION ACTUATOR REPLACEMENT - BANK 1 (RIGHT SIDE) EXHAUST - FIRST DESIGN
Special Tools: EN 46108 Timing Chain Retention Tool
Important: To identify a camshaft drive design, refer to Camshaft Timing Drive Design Identification. Locations
Removal Procedure
1. Remove the lower intake manifold. Service and Repair
2. Remove the right camshaft cover. Service and Repair
3. Remove the right intake and exhaust camshaft position sensors. Service and Repair
4. Remove the right intake and exhaust camshaft position actuator solenoids. Service and Repair
Important: Rotate the crankshaft balancer in a clockwise rotation ONLY.
5. Rotate the crankshaft using the crankshaft balancer bolt until the camshafts are in a neutral (low tension) position. The camshaft flats will be parallel with the camshaft cover rail (1).
Notice: A wrench must be used on the hex of the camshaft when loosening or tightening in order to prevent component damage. Failure to prevent the torque reaction against the timing drive chain can lead to timing drive chain failure.
Important:
• Use an open-end wrench at the camshaft hex to prevent camshaft/engine rotation.
• DO NOT remove the camshaft position actuator bolt at this time.
6. Loosen the camshaft position actuator bolt.
Important: Ensure that the tips of the EN 46108 are fully engaged into the timing chain (3 and 4).
7. Install the EN 46108 (1 and 2) in order to retain the timing chain. Firmly tighten the EN 46108 nuts.
Important: Ensure that the camshaft timing chain and the camshaft position actuators are marked for proper assembly.
8. Mark the timing chain and the respective locations on camshaft position actuators (15-18).
9. Remove the right exhaust camshaft position actuator bolt.
10. Remove the right exhaust camshaft actuator.
Installation Procedure
1. Ensure the proper camshaft position actuator is installed. Observe the body of the camshaft position actuator for the EX marking (1). The marking is for an exhaust camshaft position actuator,
2. Ensure the proper timing mark is used. Observe the outer ring of the camshaft position actuator for the triangle marking (2). The marking is for alignment to the highlighted timing chain link on the right side of the engine,
Important:
• Ensure that the marks on the camshaft position actuators and the timing chain (15-18) are aligned.
• DO NOT tighten the camshaft position actuator bolt at this time.
3. Assemble the camshaft actuator to the camshaft.
4. Loosely install the camshaft actuator bolt.
5. Remove the EN 46108.
Notice: A wrench must be used on the hex of the camshaft when loosening or tightening in order to prevent component damage. Failure to prevent the torque reaction against the timing drive chain can lead to timing drive chain failure.
Important: Use an open-end wrench at the camshaft hex to prevent camshaft/engine rotation.
6. Tighten the camshaft position actuator. 110. Camshaft Position Actuator Installation - Right Side Exhaust
