Special Tools:















CAUTION:
The magnetic timing wheels (1) must not come in contact with magnets (pickup tools, trays, etc.) or any other strong magnetic field. This will destroy the timing wheels ability to correctly relay camshaft position to the camshaft position sensor.





1. Remove the upper intake manifold, left ignition coils and left cylinder head cover Cylinder Head Cover(s) - Removal

2. Remove the right ignition coils and all spark plugs .

CAUTION:
When aligning timing marks, always rotate engine by turning the crankshaft. Failure to do so will result in valve and/or piston damage.

3. Mount Dial Indicator Set (C-3339A) (1) to a stationary point on the engine, such as the left camshaft position (CMP) sensor mount. Position the indicator probe into the number four cylinder, rotate the crankshaft clockwise (as viewed from the front) to place the number four cylinder piston at top-dead-center on the compression stroke and set the indicator dial to zero.





4. The left side cam phaser SCRIBE LINES (3) should face away from each other and the ARROWS (1) should point toward each other and be parallel to the cylinder head cover mounting surface (2) when the number four cylinder piston is positioned at top-dead-center on the compression stroke.





NOTE:
The phaser markings (1 and 3) could align with either an external or internal chain link. Either alignment is acceptable as long as there are twelve chain pins between the markings.

5. There should be twelve chain pins (2) BETWEEN the exhaust cam phaser triangle marking (3) and the intake cam phaser circle marking (1) as viewed from either the front or rear of the cam phasers.

6. Mark both sides of the cam chain at the phaser timing marks (1 and 3) using a paint pen or equivalent to aid in reassembly.





NOTE:
It may be necessary to rock the camshaft slightly (a few degrees) with a wrench (4) when installing the camshaft phaser lock.

7. Install the (10202-2) (1) against the cylinder head cover mounting surface with the tool number facing up.

8. Loosen, but do not remove, the exhaust oil control valve (2) and the intake oil control valve (3).

9. Remove the (10202-2) (1).





NOTE:
Graphic shows engine timing cover removed for clarity.

10. Using (10200-3) (2), lift the pawl off of the rack (3). While holding the pawl off of the rack, push (10200-1) (1) into place between the cylinder head boss and the tensioner arm to force the rack and piston back into the tensioner body. The Timing Chain Holder remains in place while the phasers are removed .





11. Remove the oil control valve (4) and pull the left side exhaust cam phaser off of the camshaft.

12. Remove the oil control valve (3) and pull the left side intake cam phaser off of the camshaft.
