TIMING CHAIN & SPROCKETS - INSTALLATION

1. CAUTION:Do not rotate the camshaft more than a few degrees independently of the crankshaft. Valve to piston contact could occur resulting in possible valve damage. If the camshaft 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 camshaft is returned to their top-dead-center position, rotate the crankshaft clockwise to return the crankshaft to top-dead-center.

Install the crankshaft sprocket (1) and position halfway onto the crankshaft.

2. While holding the camshaft phaser in hand, position the timing chain on the camshaft phaser and align the timing marks as shown.

4. Align the slot in the camshaft phaser with the dowel on the camshaft and position the camshaft phaser on the camshaft while sliding the crankshaft sprocket into position.

5. Install the camshaft phaser bolt (1) and tighten finger tight.

9. The timing mark located on the camshaft phaser must be properly centered between the dual marks on the timing chain while at the 12 O'clock position (1). The timing mark located on the crankshaft must be properly aligned with the single mark on the timing chain while at the 6 O'clock position (2).

10. Verify that the chains are operating smoothly. The chain must be replaced if:

• Any kinks
• Signs of binding
• Damage to the links
• Signs of wear or stretching.

11. Tighten the camshaft phaser bolt (1) to the proper (Torque Specifications) .

12. Install the oil pump (Refer to 09 - Engine/Lubrication/PICK-UP, Oil Pump/Installation).

13. Fill the engine with oil (Refer to 04 - Vehicle Quick Reference/Capacities and Recommended Fluids/Specifications) .

14. Fill the cooling system (Refer to 07 - Cooling - Standard Procedure) .

15. Connect the negative battery cable.

16. Start the engine and check for leaks.
