CYLINDER HEAD TORQUE AND SEQUENCE





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.

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 with an *.

1. Lubricate the cylinder head bolt threads with clean engine oil and install the eight M11 bolts.
2. Coat the four M8 cylinder head bolts with Mopar(R) 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.





3. Tighten the bolts in sequence using the following steps and torque values:
- Step 1: Tighten bolts 1-8, 27 Nm (20 ft. lbs.).
- Step 2: Verify that bolts 1-8, all reached 27 Nm (20 ft. lbs.), by repeating step 1 without loosening the bolts. Tighten bolts 9 thru 12 to 14 Nm (10 ft. lbs.).
- Step 3: Tighten bolts 1-8, 90 degrees.
- Step 4: Tighten bolts 1-8, 90 degrees, again. Tighten bolts 9-12, 26 Nm (19 ft. lbs.)

INTAKE MANIFOLD TORQUE AND SEQUENCE





Intake manifold retaining bolts in sequence shown 12 Nm (105 in. lbs.)

CAMSHAFT BEARING CAP TORQUE AND SEQUENCE





1. Working in 1/2 turn increments, tighten the bearing cap retaining bolts starting with the middle cap working outward.
2. Tighten the camshaft bearing cap retaining bolts to 11 Nm (100 in. lbs.).

EXHAUST MANIFOLD TORQUE AND SEQUENCE

Install remaining conical washers. Starting at the center arm and working outward, tighten the bolts and nuts to 25 Nm (18 ft. lbs.).
