Timing Drive Components: Removal
All engines
- 1.
Remove the engine front cover. For additional information, refer to Engine Front Cover .
- 2.
Rotate the crankshaft clockwise and align the timing marks on the intake Variable Camshaft Timing (VCT) assemblies as shown in illustration.
- 4.NOTE: The Camshaft Holding Tool will hold the camshafts in the Top Dead Center (TDC) position.
Install the Camshaft Holding Tool onto the flats of the LH camshafts.
- 6.NOTE: The Camshaft Holding Tool will hold the camshafts in the TDC position.
Install the Camshaft Holding Tool onto the flats of the RH camshafts.
- 7.
Mark the timing chain link that aligns with the timing mark on the LH intake VCT assembly as shown in illustration.
- 8.
Mark the timing chain link that aligns with the timing mark on the RH intake VCT assembly as shown in illustration.
- 9.NOTE: The crankshaft sprocket timing mark should be between the 2 colored links.
Mark the 2 timing chain links that align with the timing mark on the crankshaft sprocket as shown in illustration.

All engines
- 14.NOTE: Removal of the VCT oil control solenoid will aid in the removal of the primary timing chain.NOTE: A slight twisting motion will aid in the removal of the VCT oil control solenoid.NOTE: Keep the VCT oil control solenoid clean of dirt and debris.
Remove the bolt and the LH intake VCT oil control solenoid.
- 15.NOTE: Removal of the VCT oil control solenoid will aid in the removal of the primary timing chain.NOTE: A slight twisting motion will aid in the removal of the VCT oil control solenoid.NOTE: Keep the VCT oil control solenoid clean of dirt and debris.
Remove the bolt and the RH intake VCT oil control solenoid.
- 18.NOTE: Do not use power tools to remove the bolt or damage to the LH primary timing chain guide may occur.
Remove the bolt and the upper LH primary timing chain guide.
- 19.NOTE: The 2 VCT oil control solenoids are removed for clarity.NOTE: The Secondary Chain Hold Down is inserted through a hole in the top of the mega cap.
Compress the LH secondary timing chain tensioner and install the Secondary Chain Hold Down in the hole on the rear of the secondary timing chain tensioner guide and let it hold against the mega cap to retain the tensioner in the collapsed position.
- 22.NOTE: The 2 VCT oil control solenoids are removed for clarity.NOTE: The Secondary Chain Hold Down is inserted through a hole in the top of the mega cap.
Compress the RH secondary timing chain tensioner and install the Secondary Chain Hold Down in the hole on the rear of the secondary timing chain tensioner guide and let it hold against the mega cap to retain the tensioner in the collapsed position.
- 25.NOTE: Do not use power tools to remove the bolt or damage to the RH primary timing chain guide may occur.
Remove the bolt and the RH primary timing chain guide.
Engines with secondary timing chain tensioner removed
- 26.NOTE: A slight twisting motion will aid in the removal of the VCT oil control solenoid.NOTE: Keep the VCT oil control solenoid clean of dirt and debris.
Remove the LH exhaust VCT oil control solenoid.
- 29.NOTE: A slight twisting motion will aid in the removal of the VCT oil control solenoid.NOTE: Keep the VCT oil control solenoid clean of dirt and debris.
Remove the RH exhaust VCT oil control solenoid.
