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 the bolts should be replaced.

Necking can be checked by holding a straight edge against the threads (2). If all the threads do not contact the scale, the bolt should be replaced.

* - INDICATES SEALANT ON THREADS
Position the new cylinder head gasket on the locating dowels.
CAUTION: When installing cylinder head, use care not damage the tensioner arm or the guide arm.
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. The locations are identified wit *.
Lubricate the cylinder head bolt threads with clean engine oil and install the eight M11 bolts.
Coat the four M8 cylinder head bolts with Mopar® Lock and Seal Adhesive then 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.
Tighten the bolts in sequence using the following steps and torque values:
1. Step 1: Tighten bolts 1-8, 27 N.m (20 ft. lbs.).
2. Step 2: Verify that bolts 1-8, all reached 27 N.m (20 ft. lbs.), by repeating step 1 without loosening the bolts. Tighten bolts 9 thru 12 to 14 N.m (10 ft. lbs.).
3. Step 3: Tighten bolts 1-8, 90 degrees.
4. Step 4: Tighten bolts 1-8, 90 degrees, again. Tighten bolts 9-12, 26 N.m (19 ft. lbs.)
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.
Install the camshaft drive gear retaining bolt.
Install the left side secondary chain guide (Refer to ENGINE/VALVE TIMING/TIMING BELT/CHAIN AND SPROCKETS - INSTALLATION) .
Install the cylinder head access plug.
Re-set and install the left side secondary chain tensioner (Refer to ENGINE/VALVE TIMING/TIMING BELT/CHAIN AND SPROCKETS - INSTALLATION)
Remove Special Tool 8429.
Install the timing chain cover (Refer to INSTALLATION )
Install the crankshaft damper (Refer to ENGINE/ENGINE BLOCK/VIBRATION DAMPER - INSTALLATION) . Tighten damper bolt 175 N.m (130 Ft. Lbs.).
Install the power steering pump.
Install the fan blade assembly and fan shroud (Refer to COOLING/ENGINE/RADIATOR FAN - INSTALLATION) .
Install the cylinder head cover (Refer to ENGINE/CYLINDER HEAD/CYLINDER HEAD COVER(S) - INSTALLATION) .
Install the master cylinder and booster assembly (Refer to BRAKES/HYDRAULIC/MECHANICAL/POWER BRAKE BOOSTER - INSTALLATION) .
Install the intake manifold (Refer to ENGINE/CYLINDER HEAD/CYLINDER HEAD COVER(S) - INSTALLATION) .
Refill the cooling system (Refer to COOLING - STANDARD PROCEDURE) .
Raise the vehicle.
Install the exhaust pipe onto the left exhaust manifold (Refer to EXHAUST SYSTEM ).
Lower the vehicle.
Connect the negative cable to the battery.
Start the engine and check for leaks.
