 Labor Operations: Click to display a list of Labor Operations associated with this procedure


NOTE: The cylinder head bolts (4) 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

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.

CAUTION: When cleaning cylinder head and cylinder block surfaces, DO NOT use a metal scraper because the surfaces could be cut or ground. Use ONLY a wooden or plastic scraper.

1. Clean sealing surfaces of cylinder head and block
2. Lubricate bolt threads with clean engine oil and install bolts.
3. Install new head gasket over locating dowels.


4. Install cylinder head to block, assuring head is properly positioned over locating dowels.
5. Tighten bolts in sequence shown, 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.)
6. For left cylinder head installation:

  1. Install engine oil dipstick tube.
  2. Install generator.
7. For right cylinder head installation:

  1. Install cylinder head ground strap.
  2. Connect EGR valve electrical connector (if equipped).

8. Install all valvetrain components and camshafts . Tighten camshaft bearing caps in sequence shown to 12 N·m (105 in. lbs.).
9. Install primary timing chain, guides and sprockets 


10. Install coolant outlet connector (3) 


11. Install cylinder head covers 
12. Connect camshaft position sensor and crankshaft position sensor connectors.
13. Install timing chain cover 
14. Install crankshaft vibration damper 


15. Install lower and upper intake manifolds 
16. Connect oil pressure sensor connector. Install oil pressure sensor heat shield.
17. Install catalytic converter(s) 


18. Install exhaust cross-under pipe (4) 


19. Install accessory drive belts
20. Fill cooling system.
21. Connect negative cable to remote jumper terminal.
