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.

Verify that the indicator dial (1) is set to zero when the left side number four cylinder piston is positioned at top-dead-center on the compression stroke.

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.

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 10 of the Removal procedure. Refer to ASSEMBLY, VARIABLE VALVE TIMING, PHASER/OIL CONTROL VALVE, REMOVAL .

NOTE:
Minor rotation of a camshaft (a few degrees) may be required to install the camshaft phaser.
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 intake camshaft. Install and hand tighten the oil control valve (7).
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 (3). Press the exhaust cam phaser onto the exhaust cam, install and hand tighten the oil control valve (4).
The SCRIBE LINES (5) on the cam phasers should face away from each other and the ARROWS (6) should point toward each other and be parallel to the cylinder head cover mounting surface. There should be twelve chain pins (2) BETWEEN the exhaust cam phaser triangle marking (3) and the intake cam phaser circle marking (1).

NOTE:
It may be necessary to rock the camshaft slightly (a few degrees) with a wrench (4) when installing the camshaft phaser lock.
Install the Camshaft Phaser Lock (special tool #10202-2, Lock, Camshaft/Phaser, Left Side) (1) against the cylinder head cover mounting surface with the tool number facing up.
Tighten the oil control valves (2, 3) to the proper specification. Refer to TORQUE SPECIFICATIONS .
Remove the Camshaft Phaser Lock (1) and the Timing Chain Holder.

Rotate the crankshaft clockwise two complete revolutions stopping when the left side number four cylinder piston is again positioned at top-dead-center on the compression stroke. To assure correct engine timing, verify the following;
- The indicator dial is set to ZERO when the left side number four cylinder piston is positioned at top-dead-center on the compression stroke.
- The SCRIBE LINES (3) on the left side cam phasers face away from each other.
- The ARROWS (4) on the left side cam phasers point toward each other and are parallel to the cylinder head cover mounting surface.
- There are twelve chain pins (2) BETWEEN the exhaust cam phaser triangle marking (1) and the intake cam phaser circle marking (3).
If the engine timing is not correct, repeat this procedure.
Install all of the spark plugs. Refer to SPARK PLUG, INSTALLATION .
Install the right ignition coils. Refer to COIL, IGNITION, INSTALLATION .
Install the left cylinder head cover. Refer to COVER(S), CYLINDER HEAD, INSTALLATION .
Install the upper intake manifold. Refer to MANIFOLD, INTAKE, INSTALLATION .
Connect the negative battery cable and tighten nut to the proper specification. Refer to BATTERY, TORQUE, SPECIFICATIONS .
Start the engine and perform the following Powertrain Verification Tests: Refer to appropriate Testing & Diagnostics article under Engine Performance .
- 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. For any DTCs that reset, refer to the DTC INDEX .
