Fig. 13: Head bolt torquing sequence-1970-83 models

After repair job, temporarily install and tighten the two center (right and left) cylinder head bolts to 14 ft. lbs. (18 Nm).

Install the camshaft sprocket together with the timing chain onto the camshaft. Make sure that the marks made earlier, line up. If the chain will not stretch over the sprocket, the problem lies in the tensioner. Refer to the Timing Chain removal and installation procedure for the timing procedure, if necessary.

Install the cylinder head bolts. Note that two lengths are used. Tighten the bolts in sequence.
1970-71 models:
Tighten the bolts to 33 ft. lbs. (43 Nm)
Tighten the bolts to 47 ft. lbs. (61 Nm)

1972 models:
Tighten the bolts to 47 ft. lbs. (61 Nm)
Tighten the bolts to 55 ft. lbs. (71 Nm)

1973-83 models:
Tighten the bolts to 30 ft. lbs. (39 Nm)
Tighten the bolts to 44 ft. lbs. (57 Nm)
Tighten the bolts to 54-61 ft. lbs. (70-79 Nm)

To complete the installation, reverse the removal procedures. Adjust the valves to a preliminary COLD clearance of 0.2mm for the intake and 0.25mm for the exhaust. Operate the engine until it is at normal operating temperature, retighten the head bolts (loosen them slightly and retighten to the final torque figure) and adjust the valves to the HOT clearance specifications.

Hope this helps; remember to rating this answer and leave some testimonial comment about this.

Need to remove cilinderhead from a chevrolet trailblazer 2003


below are the instruction you well need to remove head .....good luck Removal Procedure
  1. Remove the air cleaner element.
  2. Remove the air cleaner outlet resonator. .
  3. Remove the powertrain control module (PCM) and engine wire harness bracket and related hoses and connections.
  4. Remove the generator.
  5. Remove the intake manifold.
  6. Remove the exhaust manifold. Do not remove the exhaust pipe from the manifold. Only have the manifold pushed off to the side of the engine.
  7. Position the A/C line out of the way towards the front of the vehicle.
  8. Disconnect the following cross-vehicle engine wiring harness connectors:
  9. • Engine coolant temperature sensor • Manifold absolute pressure (MAP) sensor • Ignition coils • Harness clamps at power steering pump • Wiring harness fastener at the right front inner fender • Throttle body • Camshaft sensors • Camshaft actuators • Fuel rail • Heated oxygen sensor (HO2S)
  10. Set aside the cross-vehicle engine wiring harness on the left side of the vehicle.
  11. Remove the camshaft cover.
  12. Partially drain the cooling system.

  13. Before performing one of the top dead center (TDC) procedures, break loose both the exhaust and intake camshaft sprocket bolts. Use a 25 mm (1 in) open end wrench on the camshaft hexes to hold the camshaft from turning. DO NOT remove the bolts.
  14. Perform one of the following methods for the service timing procedure.
  15. First Method--Rotate the engine clockwise by hand to TDC on the compression stroke by using a piston TDC indicator tool and/or dial indicator in the number 1 cylinder.
  16. First Method (continued)--The TDC indicator tool graduation marks on the shaft should note top of the piston stroke.
  17. First Method (continued)--When the piston is at TDC, the flats at the rear of the camshafts will be facing up and level when using a straight edge across the camshaft flats.
  18. Second Method--Rotate the crankshaft in the engine rotational direction clockwise until the number 1 piston is at TDC on the compression stroke. The word Delphi on the exhaust camshaft position actuator will be parallel with the cylinder head to cam cover mating surface. When the piston is at TDC, the flats at the rear of the camshafts will be facing up and level when using a straight edge across the camshaft flats. A 0.005 inch feeler gauge should not slide under the straight edge (1).
  19. Use a white paint pen or equivalent to place a reference mark on the harmonic balancer to the front cover for alignment purposes.
  20. Lower the vehicle.
  21. Important: If the timing is correct (TDC compression stroke number 1 cylinder), the camshaft flats will be in the up position.
    Install J 44221 to the back of the camshafts.
  22. Remove the upper timing chain guide to the cylinder head.
  23. Clean the timing chain and gears with brake cleaner or suitable solvent. Use a white paint pen or equivalent to place a reference mark on both timing gear sprockets and the timing chain to mark location prior to disassembly. It is recommended that the paint marks be in the 12 o'clock position.

  24. Install EN-48464 . It is important to install the tool with the proper orientation and to ensure that it is seated square against the timing chain and against the timing cover center bolt.


  25. The narrow ramp of the wedge tool needs to be placed so that it faces the timing chain.
  26. The wedge tool should be lightly seated using a couple of very light taps with a small plastic or brass hammer. The wedge tool will be fully seated against the tensioner after it moves about 25 mm (1 in).
  27. Once the tool is correctly installed, unscrew the handle and remove the handle

  28. Remove both upper cylinder head access hole plugs from the front of the cylinder head.
  29. Remove the 1 long and 2 short cylinder head bolts next to the exhaust and intake timing chain tensioner shoes and discard the bolts.
  30. Remove both upper timing chain tensioner shoe bolts.
  31. Remove the exhaust and the intake camshaft sprocket bolts. Discard the bolts.


  32. Carefully remove the exhaust and intake camshaft sprockets with the timing chain from the exhaust and intake camshafts. The illustration shows the exhaust camshaft sprocket already removed.


  33. Remove the sprockets from the chain, tie a piece of mechanic's wire on the timing chain and let it drop.


  34. Before removing the cylinder head bolts, use a drift punch and hammer to shock the bolts. This will ensure that the cylinder head bolts will not strip out the threads in the engine block or break. If a bolt breaks during engine disassembly, EN-47702 is available to assist in the removal of the remaining bolt segment.
  35. Remove the cylinder head bolts. Discard the bolts.
  36. Remove the cylinder head.
  37. Place the cylinder head on a flat, clean surface with the combustion chambers face up, in order to prevent damage to the deck face.
  38. Remove the cylinder head gasket.
  39. Discard the gasket.
  40. Remove all remaining gasket material from the engine block.
  41. Inspect the cylinder head gasket mating surface on the engine block.
  42. Clean and inspect the cylinder head.
  43. Disassemble the cylinder head if necessary.

    1. Before servicing the vehicle, refer to the precautions in the beginning of this section.
    2. Drain the cooling system.
    3. Properly relieve the fuel system pressure.
    4. Remove or disconnect the following:
      • Negative battery cable
      • Powertrain assembly
      • Intake manifold
      • Cam covers
      • Harmonic balancer
      • Timing chain front cover
      • Oil pump
      WARNING
      Align all timing marks before performing the next step.
      • Chain tensioner from the timing chain
      • Cam sprockets
      NOTE: The timing chain remains in the chain case.
      • Timing chain guides, access for the retaining screws is through the plugs at the front of the cylinder head
      • Water crossover
      • Exhaust manifold
      • Cylinder head bolts by reversing the torque sequence
      • Cylinder head and discard the gasket
      WARNING
      With the camshafts remaining in the cylinder head some valves will be open at all times. Do not rest the cylinder head on a flat service with the cylinder face down, or valve damage will result. NOTE: Clean all gasket mating surfaces. Clean the head bolt holes in the crankcase. WARNING
      Be careful when cleaning aluminum gasket surfaces to prevent damage to the sealing surfaces.
    5. Check the cylinder head for warpage; it must be less than 0.002 in. (0.05mm). If the cylinder head was resurfaced, the dimension between the combustion chamber gauge pad and the deck surface must be at least 10.5mm. To install: NOTE: Refer to Section 1 of this manual for the cylinder head torque sequence illustration. The illustration is located after the Torque Specification Chart.
