Cylinder Head Assembly

Cylinder Head






Inspect the cylinder head for out-of-flatness, using a straightedge (2) and a feeler gauge (1). Check Cylinder head in several locations. If tolerances exceed 0.0508 mm (0.002 in.) replace the cylinder head.












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.

NOTE:
The four M8 cylinder head mounting bolts (11 - 14) require sealant to be added to them before installing. Failure to do so may cause leaks.

Lubricate the cylinder head bolt threads with clean engine oil and install the ten M11 bolts.

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.

Tighten the bolts in sequence using the following steps and torque values:

Tighten bolts 1 - 10 to 27 Nm (20 ft. lbs.).

Verify that bolts 1 - 10 have all reached 27 Nm (20 ft. lbs.), by repeating step 1 without loosening the bolts.

Tighten bolts 11 - 14 to 14 Nm (89 in. lbs.).

Rotate bolts 1 - 10 an additional 90°.

Rotate bolts 1 - 10 an additional 90° again.

Tighten bolts 11 - 14 to 26 Nm (19 ft. lbs).








Camshaft Bearing Caps





Using the sequence shown, working in 1/2 turn increments, tighten the bearing cap retaining bolts to 11 Nm (8 ft. lbs.).
