CAUTION:

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 must be replaced.

Check cylinder head bolts for necking by holding a scale or straight edge against the threads. If all the threads do not contact the scale (2) the bolt must be replaced.

NOTE:
Ensure cylinder head bolt holes in the block are clean, dry (free of residual oil or coolant), and threads are not damaged.

CAUTION:
Always replace the variable valve timing filter screen (3) when servicing the head gasket or engine damage could result.
Replace the variable valve timing filter screen (3).

NOTE:
When using RTV, the sealing surfaces must be clean and free from grease and oil.

NOTE:
When using RTV, parts should be assembled in 10 minutes and tighten to final torque within 45 minutes.
Place two pea size dots of Mopar® engine sealant RTV or equivalent (1) on cylinder block as shown in illustration.

Position the new cylinder head gasket on engine block with the part number facing up. Ensure gasket is seated over the locating dowels in block.
Place two pea size dots of Mopar® engine sealant RTV or equivalent (1) on cylinder head gasket as shown in illustration.
NOTE:
The head must be installed within 15 minutes before the RTV skins.
Position cylinder head onto engine block.

Fig 5: Cylinder Head Bolt Identification

CAUTION:
This engine was built with 2 different style cylinder head bolts. Each style bolt requires a different torque value. The bolts can be identified by the short bolt head (1) and the long bolt head (2).
Measure the bolt head from the washer to the top of the bolt head. The short bolt head (1) measures 8 mm (5/16") and the long bolt head (2) measures 13 mm (1/2").
Identify whether your engine has the short head design (1) or the long head design (2).

If your bolt has the short head (1), use the following torque specifications:
- First: All to 30 N.m (25 ft. lbs.)
- Second: All to 61 N.m (45 ft. lbs.)
- Third: All to 61 N.m (45 ft. lbs.)
- Fourth: All an additional 90°
  CAUTION:
  Do not use a torque wrench for the Fourth step.
If your bolt has the long head (2), use the following torque specifications:
- First: All to 30 N.m (25 ft. lbs.)
- Second: All to 73 N.m (54 ft. lbs.)
- Third: All to 73 N.m (54 ft. lbs.)
- Fourth: All an additional 90°
  CAUTION:
  Do not use a torque wrench for the Fourth step.
