Removal Procedure
WARNING: This page is about a different variant/trim than selected.
- Remove the left secondary camshaft tensioner. Refer to Secondary Camshaft Drive Chain Tensioner Replacement - Left Side .
- Remove the left camshaft position actuator housing. DO NOT remove the camshaft actuator solenoids from the housing. Refer to Camshaft Position Actuator Housing Replacement - Left Side .
- Using the J 39946 , rotate the crankshaft until both camshaft position actuator timing marks (5, 7) are at the top of their rotation.
- Install the EN 46328 (1) to the camshafts (2).
- Use a paint stick to create a mark (1) on the timing chain link adjacent to each camshaft position actuator timing mark (2).
- Use a paint stick to create a mark on a primary chain link and intermediate primary chain sprocket tooth adjacent to the primary chain link.
- Use an open end wrench on the hex cast into the left intake camshaft to prevent the camshaft from rotating when loosening the camshaft oil control valve.
- Loosen and remove the left intake oil control valve.
- Slide the left intake camshaft actuator off of the camshaft, disengage the sprocket teeth from the secondary timing chain, and remove the actuator.
- Remove the left secondary camshaft drive timing chain shoe bolt.
- Remove the left secondary camshaft drive timing shoe.
- Clean and inspect the camshaft timing drive components. Refer to Camshaft Timing Drive Components Cleaning and Inspection .
CAUTION:
Refer to Camshaft Holding Tool Caution
.
IMPORTANT:
The secondary timing chain has black links that are used for alignment when the primary and secondary timing gear and chain assemblies are being installed together. IT IS NOT NECESSARY for the black chain links to be aligned with the camshaft actuator timing marks when the secondary chain and gear components are being serviced separately.
NOTE:
Refer to Torque Reaction Against Timing Drive Chain Notice
