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.







CAUTION: Do not rotate the crankshaft more than a few degrees independently of the camshafts. Piston to valve contact could occur resulting in possible valve damage. If the crankshaft needs to be rotated more than a few degrees, first remove the camshafts Camshaft - Removal .

1. Verify that the number one piston is positioned at top-dead-center on the exhaust stroke.





2. CAUTION: Do not rotate the camshafts more than a few degrees independently of the crankshaft. Valve to piston contact could occur resulting in possible valve damage. If the camshafts need to be rotated more than a few degrees, first move the pistons away from the cylinder heads by rotating the crankshaft counterclockwise to a position 30° before-top-dead-center. Once the camshafts are returned to their top-dead-center position, rotate the crankshaft clockwise to return the crankshaft to top-dead-center.

3. Verify that the camshafts are set at top-dead-center by positioning the alignment holes (1) vertically.






NOTE: The Timing Chain Holder (1) should still be in place as inserted during the Removal procedure. If required, the Timing Chain Holder can be reinserted by repeating Step 9 of the Removal procedure Variable Valve Timing Assembly - Removal .






4. Route the cam chain around the left intake cam phaser while aligning the paint mark with the phaser timing mark (1). Press the left intake cam phaser onto the inlet camshaft. Install and hand tighten the oil control valve (6).
5. While maintaining this alignment, route the cam chain around the exhaust cam phaser so that the paint mark is aligned with the phaser timing mark (1). Press the exhaust cam phaser onto the exhaust cam, install and hand tighten the oil control valve (2). The arrows (3) on the cam phasers should point toward each other and be parallel to the valve cover sealing surface (5).

NOTE: Minor rotation of a camshaft (a few degrees) may be required to install the camshaft phaser or phaser lock.

6. Install the LH (10202-2) (4) and tighten the oil control valves (2) and (6) to 150 Nm (110 ft. lbs.).
7. Remove the LH Camshaft Phaser Lock (4) and the Timing Chain Holder.
8. Rotate the crankshaft clockwise two complete revolutions stopping when the number one piston is again positioned at top-dead-center on the exhaust stroke.
9. While maintaining this alignment, verify that the arrows on the left side cam phasers (3) point toward each other and are parallel to the valve cover sealing surface (5).





10. There should be 12 chain pins (2) between the exhaust cam phaser triangle marking (1) and the intake cam phaser circle marking (3).
11. If the engine timing is not correct, repeat this procedure.
12. Install the spark plugs Spark Plug - Installation.
13. Install the right ignition coils Ignition Coil - Installation
14. Install the left cylinder head cover and left ignition coils Cylinder Head Cover(s) - Installation
15. Install the upper intake manifold and air cleaner housing assembly Intake Manifold - Installation
16. Connect the negative battery cable and tighten nut to 5 Nm (45 in. lbs.).
17. Start the engine and perform the following Powertrain Verification Tests Powertrain Verification Test :
- Cam/Crank Variation Relearn
- Target Coefficient Relearn

NOTE: Following the first restart after a DTC driven phaser replacement, clear all DTCs and verify that subsequent restarts do not set any additional codes. Testing and Inspection for any DTCs that reset.
