Re-index the camshaft drive gear in the chain until the V6 mark is at the same position as the V6 mark on the opposite camshaft drive gear (1, 2).
Using the Camshaft Holder (special tool #8428A, Holder, Camshaft), rotate the camshaft until the alignment dowel on the camshaft is aligned with the slot in the camshaft drive gear.
CAUTION:
Remove excess oil from camshaft sprocket retaining bolt before reinstalling bolt. Failure to do so may cause over-torqueing of bolt resulting in bolt failure.
Position the camshaft drive gear onto the camshaft, remove oil from bolt then install the retaining bolt. Using Special Tools, Spanner Wrench (special tool #6958, Wrench, Spanner) with Adapter Pins (special tool #8346, Pins, Adapter) and a suitable torque wrench, tighten the retaining bolt to 122 N.m (90 ft. lbs.)
Remove the Wedge Locking Tool (special tool #8379, Locking Tool, Wedge).
Rotate the crankshaft two full revolutions, then verify that the camshaft drive gear V6 marks are in fact aligned.
Install the cylinder head covers. Refer to COVER(S), CYLINDER HEAD, INSTALLATION, 3.7L (Left) and COVER(S), CYLINDER HEAD, INSTALLATION, 3.7L (Right).
