Specific to:
Ford Mustang 2009-2010

NOTE
The camshaft procedure must be followed exactly or damage to the valves and pistons will result.

  1. Remove the LH valve cover.
    NOTE
    Damage to the camshaft phaser and sprocket assembly will occur if mishandled or used as a lifting or leveraging device.
  2. Loosen and back off the LH camshaft phaser and sprocket bolt one full turn.
  3. Disconnect the LH Camshaft Position (CMP) sensor electrical connector.
  4. Remove the LH CMP sensor and the bolt.

  6. Remove only the 3 camshaft roller followers shown in the illustration.
    NOTE
    The camshaft roller followers must be installed in their original locations. Record camshaft roller follower locations. Failure to follow these instructions may result in engine damage.


    NOTE
    Do not allow the valve keepers to fall off the valve or the valve may drop into the cylinder. If a valve drops into the cylinder, the cylinder head must be removed.


    NOTE
    It may be necessary to push the valve down while compressing the spring.

  7. Using the Valve Spring Compressor, remove only the 3 designated camshaft roller followers from the previous step.
    NOTE
    The crankshaft cannot be moved once set or engine damage may occur.
  8. Rotate the crankshaft a half turn clockwise, as viewed from the front, positioning the No. 5 cylinder camshaft exhaust lobe at the 11 o'clock position.
    NOTE
    Engine is not freewheeling. Camshaft procedure must be followed exactly or damage to valves and pistons will result.


    NOTE
    The Timing Chain Locking Tool must be installed square to the timing chain and the engine block.


    NOTE
    Engine front cover removed from art for clarity.

  9. Install the Timing Chain Locking Tool in the LH timing chain.
    NOTE
    Do not remove the Timing Chain Locking Tool at any time during assembly. If the Timing Chain Locking Tool is removed or out of placement, the engine front cover must be removed and the engine must be retimed. Failure to follow this instruction can result in damage to the valves and pistons.


    NOTE
    The timing chain must be installed in its original position onto the camshaft phaser and sprocket using the scribed marks, or damage to valves and pistons will result.


    NOTE
    RH shown, LH similar.

    NOTE
    Damage to the camshaft phaser and sprocket assembly will occur if mishandled or used as a lifting or leveraging device.


    NOTE
    Only use hand tools to remove the camshaft phaser and sprocket bolt or damage may occur to the camshaft or camshaft phaser and sprocket.


    NOTE
    Do not remove the Timing Chain Locking Tool at any time during assembly. If the Timing Chain Locking Tool is removed or out of placement, the engine front cover must be removed and the engine must be retimed. Failure to follow this instruction can result in damage to the valves and pistons.

    NOTE
    The timing chain must be installed in its original position onto the camshaft phaser and sprocket using the scribed marks, or damage to valves and pistons will result.


    NOTE
    If replacement of the camshaft phaser and sprocket is necessary, transfer the scribe mark to the new camshaft phaser and sprocket.
  2. Position the camshaft phaser and sprocket into the timing chain with the timing chain scribe marks in alignment.
    NOTE
    Do not remove the Timing Chain Locking Tool at any time during assembly. If the Timing Chain Locking Tool is removed or out of placement, the engine front cover must be removed and the engine must be retimed.


    NOTE
