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 (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.

1. Lubricate the cylinder head bolt threads with clean engine oil and install the ten 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 1-10, 20 Nm (15 ft. lbs.).
- Step 2: Tighten bolts 1-10, 47 Nm (35 ft. lbs.). Tighten bolts 11-14, 25 Nm (18 ft. lbs.).
- Step 3: Tighten bolts 1-10, 90 degrees. Tighten bolts 11-14, 30 Nm (22 ft. lbs.).

INTAKE MANIFOLD TORQUE AND SEQUENCE

Install the ignition coils (1, 2) and manifold retaining bolts and torque from the center bolts, moving front to back in a crisscross pattern to 12 Nm (106 in. lbs.).

CAMSHAFT BEARING CAP TORQUE AND SEQUENCE





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 neutral position easing the installation of the camshaft bearing caps.

1. Install the camshaft bearing caps, hand tighten the retaining bolts.
2. Working in 1/2 turn increments, tighten the bearing cap retaining bolts following the torque sequence.
3. Tighten the camshaft bearing cap retaining bolts to 11 Nm (100 in. lbs.).

EXHAUST MANIFOLD TORQUE AND SEQUENCE

Tighten all manifold bolts starting at center and working outward to 25 Nm (18 ft. lbs.).
