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.
1. 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.
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.
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 installing the exhaust cam phaser and repeating Step 10 of the Removal procedure Variable Valve Timing Assembly - Removal .
NOTE:
Minor rotation of a camshaft (a few degrees) may be required to install the camshaft phaser.
4. Route the cam chain around the right exhaust cam phaser while aligning the paint mark with the phaser timing mark (1). Press the right exhaust cam phaser onto the exhaust camshaft. Install and hand tighten the oil control valve (7).
5. While maintaining this alignment, route the cam chain around the intake cam phaser so that the paint mark is aligned with the phaser timing mark (3). Press the intake cam phaser onto the intake cam, install and hand tighten the oil control valve (4).
6. The ARROWS (5) on the cam phasers should point away from each other and the SCRIBE LINES (6) should be parallel to the cylinder head cover mounting surface. There should be twelve chain pins (2) BETWEEN the exhaust cam phaser triangle marking (1) and the intake cam phaser circle marking (3).
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 (10202-1) (1) against the cylinder head cover mounting surface with the tool number facing up.
8. Tighten the oil control valves (2) and (3) to 150 Nm (110 ft. lbs.).
9. Remove the Camshaft Phaser Lock (1) and the Timing Chain Holder.
10. 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 ARROWS (4) on the right side cam phasers point away from each other.
- The SCRIBE LINES (5) on the right side cam phasers 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).
11. If the engine timing is not correct, repeat this procedure.
12. Install the spark plugs .
13. Install the left ignition coils
14. Install the right cylinder head cover and right 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.
