CYLINDER HEAD SPECIFICATIONS

Cylinder Head:

CYLINDER HEAD TORQUE AND SEQUENCE

NOTE: The four smaller cylinder head mounting bolts require sealant to be added to them before installing. Failure to do so may cause leaks.

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) Thread Sealant with PTFE then install the bolts.

NOTE: The cylinder head bolts are tightened using an torque angle procedure.

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.).

HEAD BOLT REUSE





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.

INTAKE MANIFOLD TORQUE AND SEQUENCE





Install intake manifold retaining bolts and tighten in sequence shown in to 12 Nm (105 in. lbs.).

CAMSHAFT BEARING CAP TORQUE AND SEQUENCE





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

CAMSHAFT SPROCKET

Camshaft Non-Oiled Sprocket Bolt 122 Nm (90 Ft. Lbs.)

EXHAUST MANIFOLD TORQUE AND SEQUENCE





1. Install exhaust manifold and gasket from below engine compartment.
2. Install lower exhaust manifold fasteners (1,2,3). DO NOT tighten until all fasteners are in place.
3. Lower vehicle and install upper exhaust manifold fasteners (1,2,3,). Tighten all manifold bolts starting at center and working outward to 25 Nm (18 ft. lbs.).

CAUTION: Over tightening heat shield fasteners, may cause shield to distort and/or crack.
