2. Position the new cylinder head gasket on the locat-
ing dowels.
CAUTION: When installing cylinder head, use care
not damage the tensioner arm or the guide arm.
3. Position the cylinder head onto the cylinder block.
Make sure the cylinder head seats fully over the
locating dowels.
NOTE: The four smaller cylinder head mounting
bolts require sealant to be added to them before
installing. Failure to do so may cause leaks.
4. Lubricate the cylinder head bolt threads with clean
engine oil and install the eight M11 bolts.
5. Coat the four M8 cylinder head bolts withMopar
Lock and Seal Adhesivethen install the bolts.
NOTE: The cylinder head bolts are tightened using
an angle torque procedure, however, the bolts are
not a torque-to-yield design.
6. Tighten the bolts in sequence using the following steps and torque values:
Step 1: Tighten bolts 1-8, 27 Nꞏm (20 ft. lbs.).
Step 2: Verify that bolts 1-8, all reached 27 Nꞏm (20 ft. lbs.), by repeatingstep 1 without loosening the bolts.
Tightenbolts9thru12to14Nꞏm(10ft.lbs.).
Step 3: Tighten bolts 1-8, 90 degrees.
Step 4: Tighten bolts 1-8, 90 degrees, again. Tighten bolts 9-12, 26 Nꞏm (19ft. lbs.)
7. Position the secondary chain onto the camshaft drive gear, making sure one marked chain link is on either side
of the V6 mark on the gear then using Special Tool 8428 Camshaft Wrench, position the gear onto the camshaft.
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.
8. Install the camshaft drive gear retaining bolt.
9. Install the left side secondary chain guide (Refer to 9 - ENGINE/VALVE TIMING/TIMING BELT/CHAIN AND
SPROCKETS - INSTALLATION).
10. Install the cylinder head access plug.
11. Re-set and install the left side secondary chain tensioner (Refer to 9 -ENGINE/VALVE TIMING/TIMING BELT/
CHAIN AND SPROCKETS - INSTALLATION).
12. Remove Special Tool 8429.
13. Install the timing chain cover (Refer to 9 - ENGINE/VALVE TIMING/TIMING BELT / CHAIN COVER(S) -
INSTALLATION).
14. Install the crankshaft damper (Refer to 9 - ENGINE/ENGINE BLOCK/VIBRATION DAMPER - INSTALLATION).
Tighten damper bolt 175 Nꞏm (130 Ft. Lbs.).
15. Install the power steering pump.
16. Install the fan blade assembly and fan shroud (Refer to 7 - COOLING/ENGINE/RADIATOR FAN - INSTALLA-
TION).
17. Install the cylinder head cover (Refer to 9 - ENGINE/CYLINDER HEAD/CYLINDER HEAD COVER(S) - INSTAL-
LATION).
18. Install the master cylinder and booster assembly (Refer to 5 - BRAKES/HYDRAULIC/MECHANICAL/POWER
BRAKE BOOSTER - INSTALLATION).
19. Install the intake manifold (Refer to 9 - ENGINE/MANIFOLDS/INTAKE MANIFOLD - INSTALLATION).
20. Refill the cooling system (Refer to 7 - COOLING - STANDARD PROCEDURE).

6. Hold the camshaft with Special Tool 8428 Camshaft
Wrench , while removing the camshaft sprocket
bolt and sprocket.
7. Using Special Tool 8428 Camshaft Wrench, gently
allow the camshaft to rotate 5° clockwise until the
camshaft is in the neutral position (no valve load).
8. Starting at the outside working inward, loosen the
camshaft bearing cap retaining bolts 1/2 turn at a
time. Repeat until all load is off the bearing caps.
CAUTION: DO NOT STAMP OR STRIKE THE CAM-
SHAFT BEARING CAPS. SEVERE DAMAGE WILL
OCCUR TO THE BEARING CAPS.
NOTE: When the camshaft is removed the rocker
arms may slide downward, mark the rocker arms
before removing camshaft.
9. Remove the camshaft bearing caps and the
camshaft.
INSTALLATION
1. 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 neu-
tral position easing the installation of the camshaft
bearing caps.
2. Position the camshaft into the cylinder head.
3. 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.
4. Working in 1/2 turn increments, tighten the bearing
cap retaining bolts starting with the middle cap
working outward.
5. Torque the camshaft bearing cap retaining bolts to
11 N ꞏm ( 1 0 0 i n . l b s . ) .
6. Position the camshaft drive gear into the timing chain aligning the V6 mark between the two marked chain links
(Two links marked during removal).
7. 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.
8. Remove excess oil from bolt, then install the camshaft sprocket retaining bolt and hand tighten.
9. Remove Special Tool 8379 timing chain wedge.

INSTALLATION
1. coat the valve stem with clean engine oil and insert
it into the cylinder head.
2. Install the valve stem seal. make sure the seal is
fully seated and that the garter spring at the top of
the seal is intact.
3. Install the spring and the spring retainer.
4. Using the valve spring compressor, compress the
spring and install the two valve spring retainer
halves.
5. Release the valve spring compressor and make
sure the two spring retainer halves and the spring
retainer are fully seated.
6. lubricate the camshaft journal with clean engine oil
then Position the camshaft (with the sprocket dowel
on the left camshaft at 11 o’clock and the right
camshaft at 12 o’clock), then position the camshaft
bearing caps.
7. Install the camshaft bearing cap retaining bolts.
Tighten the bolts 9-13 Nꞏm (100 in. lbs.) in 1/2 turn
increments in the sequence shown .
8. Position the hydraulic lash adjusters and rocker
arms (Refer to 9 - ENGINE/CYLINDER HEAD/
ROCKER ARM / ADJUSTER ASSY -
INSTALLATION).
