2. 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.
3. Position the cylinder head onto the cylinder block. Make sure the cylinder head seats fully over the locating dowels.
   NOTE: The four M8 cylinder head mounting bolts (1) 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 M10 bolts.
5. 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.
6. Tighten the bolts in sequence using the following steps and torque values. See Fig 3:
   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°.
   4. Step 4: Tighten bolts 1-8, 90°, again. Tighten bolts 9-12, 26 N.m (19 ft. lbs.)

7. Position the secondary chain (2) onto the camshaft drive gear, making sure one marked chain link is on either side of the V6 mark (1) on the gear then using the Camshaft Holder 8428, position the gear onto the camshaft. See Fig 4 and Fig 5.
   CAUTION: Remove excess oil from camshaft sprocket retaining bolt before reinstalling bolt. Failure to do so may cause over-torquing of bolt resulting in bolt failure.
8. Install the camshaft drive gear retaining bolt.
9. Install the right side secondary chain guide. See INSTALLATION .
