    CAUTION: Refer to Battery Disconnect Caution in Cautions and Notices.
  1. Disconnect the negative battery cable.
  2. Disconnect the intake air temperature (IAT) sensor connector.
  3. Loosen the clamp at the air cleaner assembly.
  4. Remove the push pin attachment from the outlet resonator/duct assembly to support bracket.
  5. Loosen the clamp at the throttle body assembly.
  6. Disconnect the positive crankcase ventilation (PCV) fresh air vent hose at the cam cover.
  7. Remove the outlet resonator/duct assembly.

  8. Disconnect the electrical connector at the ignition module.
  9. Remove the ignition module assembly with bolts.
  10. Disconnect the coolant de-gas hose clip on the fuel rail.
    11. CAUTION: Whenever fuel line fittings are loosened or disconnected, wrap a shop cloth around the fitting to collect fuel. Place the cloth in an approved container.
    NOTE: An open-end wrench must be used to support the fuel line to rail connection during loosening/tightening to avoid damaging the fuel rail assembly.

  11. Disconnect the ground strap at the rear of the cam cover assembly.
  12. Relieve the fuel system pressure. Refer to Fuel Pressure Relief Procedure in Engine Controls - 2.2L (L61).
  13. Disconnect the gage bar set SA9127E-7  after the pressure has been relieved. See Special Tools .

  14. Disconnect the fuel ail bracket and bolt at the rear of the cam.
  15. While supporting the fuel rail assembly with an open-end wrench, loosen the transfer line fitting at fuel.
    16. Fig 5: Positioning Fuel Line

  16. Position the fuel line away from the cam cover assembly.
  17. Remove the cam cover assembly bolts.
  18. Remove the cam cover assembly.
    19. Fig 6: Locating Purge Solenoid

  19. Remove the purge solenoid from the power steering plate.
  20. Remove the power steering block off plate if the intake camshaft is being removed.
    21. NOTE: To avoid valve piston contact, No. 1 cylinder piston must be positioned at approximately 60 degrees before-top dead center (BTDC). Pistons are properly positioned when the diamond shaped hole on the intake camshaft sprocket is located at 12 o'clock.
    IMPORTANT: To rotate camshafts, use a 24 mm open end wrench on camshaft flats. Camshafts should be rotated in a clockwise direction only, facing camshaft sprockets from passenger side of the vehicle.

    IMPORTANT: When removing guide bolts, do not drop the bolt down into the front cover area
  21. Locate the number 1 piston to approximately 60 degrees before top dead center, diamond shaped hole on the intake camshaft sprocket at the 12 o'clock position. Remove the spark plugs. This will ease rotation effort.
    22. Fig 8: Removing/Installing Upper Timing Chain Guide

  22. Remove the upper timing chain guide.
    23. NOTE: During camshaft removal procedure, the pistons are locked in position by the J 43655. DO NOT rotate the engine crankshaft or tool damage and timing reset will be required. Camshafts an be rotated ONLY AFTER the #1 piston is at 60 degrees before top dead center (BTDC) and sprocket had been disengaged from camshaft.
  23. Remove the front camshaft caps.
    24. IMPORTANT: Lubricate the sprocket pins with clean motor oil. This will allow the sprockets to easily slide on the sprocket pins.
    Fig 9: Installing J43655 Through The Sprocket Holes

  24. Install the J 43655  through the sprocket holes from the timing side of the sprocket towards the rear of the engine. See Special Tools .
  25. With guide pin installed in the sprocket, align the guide pins into the slots on the support plate.
    26. Fig 10: View Of Support Bracket Installed On Cylinder Head

    NOTE: Refer to Fastener Notice in Cautions and Notices.
  26. Tighten the support bracket to cylinder head.

    Tighten:  Tighten the support plate to cylinder head to 10 N.m (89 lb in).

  27. Install the wing nuts and tighten.
    28. Fig 11: Removing/Installing Camshaft Timing Sprocket Retaining Bolts & Washers
    GM896709Courtesy of GENERAL MOTORS CORP.
  28. Hold each camshaft in place using a 24 mm open end wrench and carefully remove the camshaft sprocket timing retaining bolts and washers. Discard the torque-to-yield bolts.
    29. IMPORTANT:
    • When sliding the timing chain and sprocket onto the guide pins, be sure the timing chain is positioned properly on the adjustable and fixed guide or guide damage will occur. Care should be taken when removing the sprockets from the camshafts.
    • Camshafts are spring loaded and may rotate. Care should be taken until all spring tension is removed from the camshaft.
  29. Slide the camshaft sprockets away from the camshafts.
  30. To release the spring tension on the camshaft, after the camshaft is disengaged from the sprocket, rotate the camshaft using a 24 mm wrench to a neutral position.
