Cylinder Head: Installation

WARNING: This page is about a different car, the 2005 Dodge Stratus and 2005 Chrysler Sebring. However, it is still accessible from the selected car via links, so may be relevant.
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 must be replaced. See Fig 1

Necking can be checked by holding a straight edge against the threads. If all the threads do not contact the scale, the bolt must be replaced. See Fig 1

  1. Clean sealing surfaces of cylinder head and block (Refer to ENGINE - STANDARD PROCEDURE)  .
  2. Install new head gasket over locating dowels.
  3. Install cylinder head to block, assuring head is properly positioned over locating dowels.
  4. Lubricate bolt threads with clean engine oil and install bolts.
  5. Tighten bolts in sequence shown in Fig 2, using the following steps and torque values:
    1. Step 1: Bolts 1-8 to 48 N.m (35 ft. lbs.)
    2. Step 2: Bolts 1-8 to 75 N.m (55 ft. lbs.)
    3. Step 3: Bolts 1-8 to 75 N.m (55 ft. lbs.)
    4. Step 4: Bolts 1-8 to +90° Turn Do not use a torque wrench for this step. 
    5. Step 5: Bolts 9-11 to 28 N.m (250 in. lbs.)
