Verify the timing marks on the camshaft sprockets and the crankshaft sprocket with the colored links.

With the camshafts still locked at TDC, remove the mounting bolts from the VCT units (camshaft sprockets), then remove the sprockets and secondary timing chains from the camshafts.

The steps must be read carefully and disassembly must proceed using the special tools, otherwise damage to the engine will result.

71. Install the primary timing chain guide for the rear (right) cylinder bank and tighten the bolts to the torque. 72. Tilt the rear (right) cylinder bank camshaft holding tool to the rear and install the secondary timing chain tensioner, tightening the bolts to the torque. Don't remove the lock pin from the tensioner yet. 73. Install the secondary timing chains onto the camshaft sprockets. The colored links on the chain must align with the marks/camshaft keyway slots in the sprockets. 74. Install the sprockets/VCT actuator (phaser)/secondary timing chain onto the rear camshafts. When installing the camshaft sprocket bolts, NEW bolts must be used. Tighten the bolts to the torque. 75. Tilt the front (left) cylinder bank camshaft holding tool to the rear and install the secondary timing chain tensioner, tightening the bolts to the torque. Don't remove the lock pin from the tensioner yet. 76. Install the sprockets/VCT actuator (phaser)/secondary timing chain (with the marks aligned as shown in illustration 9.27) onto the front camshafts. When installing the camshaft sprocket bolts, NEW bolts must be used. Tighten the bolts to the torque. Remove the lock pin from the tensioner. 77. Install the crankshaft sprocket. 78. Install the primary timing chain onto the crankshaft sprocket and the VCT sprockets, making sure the colored links (or marks) on the chain align with the marks on the sprockets. 79. Install the upper chain guide on the front (left) cylinder bank, tightening the bolts to the torque. 80. Install the lower chain guide for the front cylinder bank, tightening the bolts to the torque. 81. Install the primary timing chain tensioner arm to the rear cylinder bank. Place the timing chain tensioner in a soft-jawed vise, with the jaws bearing on the tensioner body and the plunger. Swing the lever on the tensioner counterclockwise, then tighten the vise until the tensioner plunger has been retracted. Swing the lever clockwise, aligning the hole in the lever with the hole in the tensioner body, then install a lock pin made of wire, or a drill bit or small Allen wrench. Remove the tensioner from the vise. 82. Install the primary timing chain tensioner, tightening the bolts to the torque. Remove the lock pin from the tensioner. 83. Recheck the timing marks to make sure they are all in proper alignment. 84. Check the seals on the VCT housing, replacing them if necessary. 85. Install the VCT housings, making sure the dowels engage completely with their corresponding holes in the cylinder head. Install the bolts and tighten them a little at a time to the torque. 86. Remove the camshaft holding tools, then rotate the engine by hand at least two revolutions and verify that there is no binding. Caution: If any resistance is felt, STOP; double-check your work and find out why. 87. Install the timing chain cover. 88. Reinstall the engine/transaxle. Refill the engine with oil (install a new filter) and coolant.
