    3.2L & 3.5L Engines





    1. Before servicing the vehicle, refer to the Precautions section.






    This engine uses aluminum alloy cylinder heads. Use care when
    working with light alloy components. The heads are common to either
    cylinder bank, but in practice a cylinder head should be returned to the
    side of the engine from which it was removed. Removal of a cylinder
    head involves removal of the timing belt. Great care is required to
    install the belt, paying attention to all valve timing marks. Please
    note that camshaft removal on this engine does require the removal of
    the cylinder head.





    1. Properly relieve the fuel system pressure.


    2. Drain the cooling system.


    3. Remove or disconnect the following:



      NOTE

      Cover the lower intake manifold during service.






      NOTE

      Mark the timing belt running direction for installation. Align the
      camshaft sprockets with the marks on the rear covers.





      Negative battery cable

      Radiator and cooling fan assemblies
      Air cleaner assembly and intake manifold
      plenum


      Accessory drive belts

      Crankshaft damper using the proper puller
      Engine valve covers
      Timing belt covers


      Timing belt and tensioner




    4. Pre-load the timing belt tensioner as follows:



      1. Place tensioner in a vise the same way it is mounted on the
        engine.



      2. Slowly compress the plunger into the tensioner body.


      3. Once the plunger is compressed, install a pin through the body and
        plunger to retain it in place until the tensioner is installed.







    5. Hold the camshaft sprocket with a 36mm box wrench, loosen and
      remove the sprocket retaining bolt and washer.




      NOTE

      To remove the camshaft sprocket retainer bolt while the engine is
      in the vehicle, it may be necessary to raise that side of the engine due
      to the length of the retainer bolt. The right bolt is 8.370 in.
      (212.6mm) long, while the left bolt is 10.0 in. (253mm) long. These
      bolts are not interchangeable and their original location during removal
      should be noted.






    6. Remove or disconnect the following:



      NOTE

      The camshaft sprockets are not interchangeable.






      NOTE

      If the right timing belt cover is to be removed, there are O-rings
      located behind it for the water pump passages.

    To install:













    Fig. Cylinder head bolt tightening sequence-3.5L engines








    1. Thoroughly clean and dry the mating surfaces of the head and
      block.




      WARNING

      When cleaning the cylinder head and block mating surfaces, do not
      use a metal scraper because the soft aluminum surfaces could be cut or
      damaged. Instead, use a scraper made of wood or plastic.






    2. Check the cylinder head for cracks, damage or engine coolant
      leakage. Check the head for flatness. End-to-end, the head should be
      within 0.002 in. (0.051mm) normally with 0.008 in. (0.203mm) the maximum
      allowed out of true. The resurface limit is 0.008 in. (0.203mm)
      maximum, the combined total dimension of stock removal from the cylinder
      head, if any, and block top surface.



    3. Place a new head gasket on the cylinder block locating dowels,
      being sure the gasket is on the correct side.

    1. Inspect the cylinder head bolts for necking (stretching) by
      holding a straightedge against the threads of each bolt. If all of the
      threads are not contacting the scale, the bolt should be replaced.




      WARNING

      Due to the cylinder head bolt torque method used, it is imperative
      that the threads of the bolts be inspected for necking prior to
      installation. If the threads are necked down, the bolt should be
      replaced. Failure to do so may result in parts failure or damage. New
      bolts are always recommended.






    2. Install the cylinder head into position on the engine block and
      over the dowels. Install the cylinder head bolts, lubricating the
      threads with clean engine oil prior to installation.



    3. Torque the cylinder head bolts using the proper sequence as
      follows:





      1. Step 1: torque in sequence to 45 ft. lbs. (61 Nm).


      2. Step 2: torque in sequence to 65 ft. lbs. (88 Nm).


      3. Step 3: torque in sequence to 65 ft. lbs. (88 Nm).



      4. Step 4: torque in sequence an additional
        1
        /
        4
        turn by using a torque angle meter.




        NOTE

        Inspect the bolt torque after tightening. The torque should be
        over 90 ft. lbs. (122 Nm). If not, replace the cylinder head bolt.










    4. Install the rear timing belt cover bolts and torque as follows:





      1. M6 bolts: 105 inch lbs. (12 Nm).


      2. M8 bolts: 21 ft. lbs. (28 Nm).


      3. M10 bolts: 40 ft. lbs. (54 Nm).





    5. Install the intake manifold assembly and torque the bolts
      following the proper sequence to 21 ft. lbs. (28 Nm).




      NOTE

      The following procedure can only be used when the camshaft
      sprockets have been loosened or removed from the shafts.






    6. When the camshaft sprockets are loosened or removed, the camshafts
      must be timed to the engine. Install the Camshaft Alignment tools
      6642-A, to the rear of the cylinder heads.



    7. Install both camshaft sprockets to the appropriate shafts. The
      left camshaft sprocket has the Distributorless Ignition System (DIS)
      pickup as part of the sprocket.



    8. Apply thread locking compound to the threads of the camshaft
      sprocket retainer bolts and install to the appropriate shafts. The right
      bolt is 8.380 in. (21.3cm) long, while the left bolt is 10.0 in.
      (25.4cm) long. These bolts are not interchangeable. Do not tighten the
      bolts at this time. The camshaft marks should be positioned between the
      marks on the cover.



    9. Place the crankshaft sprocket to the Top Dead Center (TDC) mark on
      the oil pump housing. Install the timing belt starting at the
      crankshaft sprocket and working in a counterclockwise direction.



    10. After the belt is installed around the last sprocket keep tension
      on the belt until it is past the tensioner pulley.



    11. Holding the tensioner pulley against the belt, install the
      tensioner housing and torque to 21 ft. lbs. (28 Nm).



    12. When the tensioner is in place pull the retainer pin to allow the
      tensioner to extend to the pulley bracket.



    13. Hold the right camshaft sprocket hex with a 36mm box wrench and
      torque the right camshaft sprocket bolt to 75 ft. lbs. (102 Nm). Turn
      the sprocket bolt an additional 90 degrees.



    14. Hold the left camshaft sprocket hex with a 36mm box wrench and
      torque the left camshaft sprocket bolt to 85 ft. lbs. (115 Nm). Turn the
      sprocket bolt an additional 90 degrees.



    15. Install or connect the following:


      Camshaft alignment tools from the back of the cylinder heads

      Cam covers and new O-rings. Torque the
      fasteners to 20 ft. lbs.
      (27 Nm). Repeat this procedure on the other camshaft.
      Timing belt covers and crankshaft damper and
      torque the crankshaft
      damper bolt to 85 ft. lbs. (115 Nm)
      Valve covers and torque the bolts to 105
      inch lbs. (12 Nm)
      Spark plug tube nut and O-ring and torque to
      60 inch lbs. (7 Nm)
      Spark plug and torque to 20 ft. lbs. (28 Nm)
      A/C compressor and torque the mounting
      bracket bolts to 30 ft.
      lbs. (41 Nm)
      Spark plug wires
      Accessory drive belts and adjust to the
      proper tension
      Intake manifold plenum using the recommended
      procedure
      Air cleaner assembly
      Radiator and cooling fan assemblies
      Negative battery cable





    16. Check to be sure that all hoses, wiring connectors, cables, fluid
      and vacuum lines are reconnected.



    17. Change the engine oil and oil filter.


    18. Fill and bleed the cooling system.


    19. Run the vehicle with the radiator cap off so coolant can be added
      as required until the thermostat opens. Watch for leaks and for unusual
      engine noises. Refill the radiator completely as required.



    20. Once the vehicle has cooled, recheck the coolant and oil level.

Im replacing the head gasket what is the tourq and sequence for instillation


A torque specification is how tight you must make the bolt by using a torque wrench which measures the tightness you apply to the bolt, ensure you are using new head bolts, a reliable torque wrench, clean the threads of the cylinder head (with tap) where head bolts screw into and when installing bolts ensure they are properly lubricated. And the sequence is the order in which you tighten each bolt.
