Section 501 (3.7L Engine (Service Information)): Camshaft: Installation

WARNING: This page is about a different car, the 2005 Jeep Liberty. However, it is still accessible from the selected car via links, so may be relevant.

Lubricate camshaft journals with clean engine oil.
NOTE: Position the left side camshaft so that the camshaft sprocket dowel is near the 1 o'clock position, This will place the camshaft at the neutral position easing the installation of the camshaft bearing caps.
Position the camshaft into the cylinder head.
Install the camshaft bearing caps, hand tighten the retaining bolts.
NOTE: Caps should be installed so that the stamped numbers on the caps are in numerical order, ( 1 thru 4 ) from the front to the rear of the engine. All caps should be installed so that the stamped arrows on the caps point toward the front of the engine.
Working in 1/2 turn increments, tighten the bearing cap retaining bolts starting with the middle cap working outward. See Fig 1.

Torque the camshaft bearing cap retaining bolts to 11 N.m (100 in. lbs.).
Position the camshaft drive gear into the timing chain aligning the V6 mark between the two marked chain links (Two links marked during removal).
Using Special Tool 8428 Camshaft Wrench, rotate the camshaft until the camshaft sprocket dowel is aligned with the slot in the camshaft sprocket. Install the sprocket onto the camshaft.
CAUTION: Remove excess oil from camshaft sprocket bolt. Failure to do so can cause bolt over-torque resulting in bolt failure.
Remove excess oil from bolt, then install the camshaft sprocket retaining bolt and hand tighten.
Remove Special Tool 8379 timing chain wedge.
Using Special Tool 6958 spanner wrench with adapter pins 8346, torque the camshaft sprocket retaining bolt to 122 N.m (90 ft. lbs.).
Install the cylinder head cover.
