3. Pry up 4 spring clips and lock cover to housing.
4. Install air duct to air cleaner cover and tighten hose clamp to 3 Nꞏm (30 in.lbs.)torque.
5. If any other hose clamps were removed from air intake system, tighten themto3.4Nꞏm(30in.lbs.)torque.
6. If any bolts were removed from air resonator housing or air intake tubing, tighten them to 4.5 Nꞏm (40 in. lbs.)
torque.

13. Verify the V8 mark on the camshaft sprocket is at the 12 o’clock position. Rotate the crankshaft one turn if
necessary.

AND SPROCKETS - REMOVAL).
19. Remove the cylinder head access plug (2).
20. Remove the left side secondary chain guide
(Refer to 9 - ENGINE/VALVE TIMING/TIMING
BELT/CHAIN AND SPROCKETS - REMOVAL).
21. Remove the retaining bolt and the camshaft drive
gear.
CAUTION: Do not allow the engine to rotate.
Severe damage to the valve train can occur.
CAUTION: Do not overlook the four smaller bolts
at the front of the cylinder head. Do not attempt to
remove the cylinder head without removing these
four bolts.
NOTE: The cylinder head is attached to the cylin-
der block with fourteen bolts.
22. Remove the cylinder head retaining bolts using
the sequence provided.
23. Remove the cylinder head and gasket. Discard
the gasket.

12. Verify the V8 mark on the camshaft sprocket is at the 12 o’clock position(2). Rotate the crankshaft one turn if
necessary.
13. Remove the crankshaft damper (Refer to 9 - ENGINE/ENGINE BLOCK/VIBRATION DAMPER - REMOVAL).
14. Remove the timing chain cover (Refer to 9 - ENGINE/VALVE TIMING/TIMINGBELT / CHAIN COVER(S) -
REMOVAL).
15. Lock the secondary timing chains to the idler
sprocket using Special Tool 8515 (6).
NOTE: Mark the secondary timing chain prior to
removal to aid in installation.
16. Mark the secondary timing chain, one link on
each side of the V8 mark on the camshaft drive
gear.
17. Remove the right side secondary chain tensioner
(Refer to 9 - ENGINE/VALVE TIMING/TIMING
BELT/CHAIN AND SPROCKETS - REMOVAL).

18. Remove the cylinder head access plug (1).
19. Remove the right side secondary chain guide
(Refer to 9 - ENGINE/VALVE TIMING/TIMING
BELT/CHAIN AND SPROCKETS - REMOVAL).
20. Remove the retaining bolt and the camshaft drive
gear.
CAUTION: Do not allow the engine to rotate.
severe damage to the valve train can occur.
CAUTION: Do not overlook the four smaller bolts
at the front of the cylinder head. Do not attempt to
remove the cylinder head without removing these
four bolts.
CAUTION: Do not hold or pry on the camshaft tar-
get wheel for any reason. A damaged target wheel
can result in a vehicle no start condition.
NOTE: The cylinder head is attached to the cylin-
der block with fourteen bolts.
21. Remove the cylinder head retaining bolts using
the sequence provided.
22. Remove the cylinder head and gasket. Discard the gasket.
CAUTION: Do not lay the cylinder head on its gasket sealing surface, do to the design of the cylinder head
gasket any distortion to the cylinder head sealing surface may prevent thegasket from properly sealing
resulting in leaks.
CLEANING
To ensure engine gasket sealing, proper surface preparation must be performed, especially with the use of alumi-
num engine components. (Refer to 9 - ENGINE - STANDARD PROCEDURE)
INSPECTION
1. Inspect the cylinder head for out-of-flatness, using a straightedge and a feeler gauge. If tolerances exceed
0.0508 mm (0.002 in.) replace the cylinder head.
2. Inspect the valve seats for damage. Service the valve seats as necessary.
3. Inspect the valve guides for wear, cracks or looseness. If either condition exist, replace the cylinder head.

INSTALLATION
INSTALLATION - LEFT CYLINDER HEAD
NOTE: The cylinder head bolts are tightened using
a torque plus angle procedure. The bolts must be
examined BEFORE reuse. If the threads are
necked down (2) the bolts should be replaced.
Necking can be checked by holding a straight edge
against the threads. If all the threads do not contact
the scale, the bolt should be replaced.
CAUTION: When cleaning cylinder head and cylin-
der block surfaces, DO NOT use a metal scraper
because the surfaces could be cut or ground. Use
only a wooden or plastic scraper (1).
1. Clean the cylinder head and cylinder block mating
surfaces.
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 ten 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 1–10, 20 Nꞏm (15 ft. lbs.).
Step 2: Tighten bolts 1–10, 47 Nꞏm (35 ft. lbs.). Tighten bolts 11–14, 25 Nꞏm(18 ft. lbs.).
Step 3: Tighten bolts 1–10, 90 degrees. Tighten bolts 11–14, 30 Nꞏm (22 ft. lbs.).
7. Position the secondary chain onto the camshaft drive gear, making sure one marked chain link is on either side
of the V8 mark on the gear and position the gear onto the camshaft.
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 (2).
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 8515 (6).
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).
15. Install the power steering pump.
16. Install the fan blade assembly and fan shroud
(Refer to 7 - COOLING/ENGINE/FAN DRIVE VIS-
COUS CLUTCH - INSTALLATION).
17. Install the cylinder head cover (Refer to 9 -
ENGINE/CYLINDER HEAD/CYLINDER HEAD
COVER(S) - INSTALLATION).
18. Reinstall the master cylinder and booster assem-
bly.Refertosection5brakes.
19. Install the intake manifold (Refer to 9 - ENGINE/
MANIFOLDS/INTAKE MANIFOLD - INSTALLA-
TION).
20. Refill the cooling system (Refer to 7 - COOLING -
STANDARD PROCEDURE).
21. Raise the vehicle.
22. Install the exhaust pipe onto the left exhaust man-
ifold.
23. Lower the vehicle.
24. Connect the negative cable to the battery.
25. Start the engine and check for leaks.
