Installation Procedure

1. Install the timing chain drive sprocket to the crankshaft.
2. Rotate the crank so that the mark on the sprocket is at the 5 o'clock position.

3. Assemble the chain to the intake camshaft sprocket alignment copper link to the INT diamond timing mark on the camshaft sprocket.

Important: When lowering the timing chain rotate the assembly 90 degrees to allow the chain to fall between the cylinder block bosses, then rotate the assembly back so that the camshaft sprocket is facing forward.

4. Lower the assembly through the chain housing opening on top of the cylinder head. Use care to make sure that the chain goes around both sides of the cylinder block bosses.

Important: The crankshaft sprocket timing mark will be at approximately the 5 o'clock position.

5. Route the chain around the crankshaft sprocket and align the silver link to the timing mark.

Important: The camshaft sprocket bolt is not reusable. It is a TTY bolt, and must be discarded to prevent premature failure.

6. Install the intake camshaft sprocket loosely onto the intake camshaft and install the new camshaft sprocket bolt finger tight. It is not necessary to align the sprocket-to-camshaft offset notch at this time.

Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

Important: There is a 2nd design adjustable guide with a contact pad for the 2nd design notched tensioner. A 2nd design guide should be used only with 2nd design tensioner.

7. Install the adjustable timing chain guide through the opening on top of the cylinder head and install the chain guide bolt. Tighten the timing chain guide (adjustable) bolt to 10 Nm (89 lb in) .

8. Install the exhaust camshaft sprocket loosely onto the exhaust camshaft with the timing mark on the sprocket aligned with the silver link and install the new camshaft sprocket bolt finger tight. It is not necessary to align the sprocket-to-camshaft offset notch at this time.

Important: The camshaft sprocket bolt is not reusable. It is a TTY bolt, and must be discarded to prevent premature failure.

9. Align the camshaft sprocket-to-camshaft and tighten the camshaft bolt using the following procedure:

Notice: Do not rotate either camshaft more than half turn in either direction with crankshaft at top dead center (TDC). To do so may cause valve to piston contact resulting in a damaged valve and/or a damaged piston.

10. Ensure the sprocket timing mark is at the 5 o'clock position.

11. Rotate the intake camshaft using a 24 mm wrench on the flats of the camshaft until the sprocket-to-camshaft alignment notch seats.
12. When the sprocket seats on the camshaft, tighten the sprocket bolt finger tight.
13. Rotate the exhaust camshaft using a 24 mm wrench on the flats of the camshaft until the sprocket-to-camshaft alignment notch seats.
14. When the sprocket seats on the camshaft, tighten the sprocket bolt finger tight.

15. Verify that all colored links are aligned with the appropriate marks on the camshaft and crankshaft sprockets. If they are not, repeat steps 8-10. Install the fixed timing chain guide and bolts. Tighten the timing chain guide (fixed) bolts to 10 Nm (89 lb in) .

16. Install the fixed timing chain guide bolt access hole plug. Tighten the timing chain guide bolt access hole plug to 40 Nm (30 lb ft) .

17. Install the upper timing chain guide and bolts. Tighten the timing chain guide (upper) bolts to 10 Nm (89 lb in) .

Notice: Use a 24 mm wrench to support the camshaft while applying torque to camshaft sprocket bolt. Do not torque camshaft bolts against timing chain, as it may damage the timing chain.

18. Tighten the intake and exhaust camshaft sprocket bolts. Tighten the camshaft sprocket bolts to 85 Nm (63 lb ft) plus 30 degrees .

Important: There is a 2nd design tensioner with a notch at the plunger end of the tensioner. This tensioner should be used only with the 2nd design adjustable guide.

19. Install the sealing ring and tensioner assembly. Tighten the timing chain tensioner to 75 Nm (55 lb ft) .

20. Install the timing chain oil nozzle and bolt. Tighten the timing chain oil nozzle bolt to 10 Nm (89 lb in) .

21. Install the camshaft cover assembly.

22. Install the engine front cover.
23. Connect the negative battery cable. Tighten the battery terminal bolts to 17 Nm (13 lb ft) .

Important: camshaft sprocket bolt is not reusable. It is a torque-to-yield (TTY) bolt, and must be discarded to prevent premature failure.
3. Install new damper pulley bolt and washer. Torque:Do not reuse old bolt.
There you go.
