Variable Camshaft Timing (VCT) Unit: Installation

Left hand units 

1. Position the secondary timing chain onto the VCT assemblies. Align the colored links on the secondary timing chain with the timing marks on the VCT assemblies as shown below in the illustration.
   • The timing mark on the intake VCT assembly should align between the 2 consecutive colored links.
   • The timing mark on the exhaust VCT assembly should align with the single colored link.

2. Install the VCT assemblies and the secondary timing chain onto the camshafts. The timing mark on the exhaust VCT assembly should be approximately in the 1 o'clock position.

3. NOTE: It may be necessary to rotate the exhaust camshaft slightly (using a wrench on the flats of the camshaft) to seat the VCT assemblies onto the camshafts.

   Rotate the secondary timing chain tensioner clockwise 45 degrees so the ramped area is facing forward and fully seat the VCT assemblies onto the camshafts.

   • If the secondary timing chain is not centered over the tensioner, reposition the VCT assemblies until the y are fully seated on the camshafts.

4. NOTE: Use a wrench on the flats of the camshaft to hold the camshafts while tightening the VCT assembly bolts.

8. NOTE: It may be necessary to rotate the exhaust camshaft slightly (using a wrench on the flats of the camshaft) to seat the VCT assemblies onto the camshafts.

   Rotate the secondary timing chain tensioner counterclockwise 45 degrees so the ramped area is facing forward and fully seat the VCT assemblies onto the camshafts.

   • If the secondary timing chain is not centered over the tensioner, reposition the VCT assemblies until the y are fully seated on the camshafts.
