Removal

CAUTION: During engine repair procedures, cleanliness is extremely important. Any foreign material, including any material created while cleaning gasket surfaces that enters the oil passages, coolant passages or the oil pan, can cause engine failure.

1. With the vehicle in NEUTRAL, position it on a hoist.
2. Disconnect the battery ground cable.





4. Remove the RH and LH Variable Cam Timing (VCT) bush carriers.





5. Remove the Crankshaft Position (CKP) sensor and the torque converter cover.





6. NOTE: There is one window on the ignition pulse wheel that is unique to accept the special tool.

Install the special tool.
^ Turn the crankshaft to 45 degrees ATDC. The crankshaft keyway will be in the 6 o'clock position.
^ Install the special tool.





7. Make sure the flats of the camshaft are facing upward. If not, repeat Step 5.





8. CAUTION: The flats on the camshaft must completely contact the special service tool or damage to the camshafts can occur. Slowly draw the special tool down evenly until it is fully seated on the camshaft flats.

Install the special tool on the RH cylinder head.





9. CAUTION: An open end wrench must be used on the flats of the camshaft or damage to the camshaft will occur.

Remove and discard the RH exhaust camshaft sprocket bolt.





10. CAUTION: An open end wrench must be used on the flats of the camshaft or damage to the camshaft will occur.

Remove and discard the RH VCT unit bolt.





11. Remove the RH timing chain tensioner.
1 Push the lever down and install a drill rod to lock the piston.
2 Remove the 2 bolts and the tensioner.





12. Remove the bolt and the RH tensioner arm.





13. Remove the bolt and the RH timing chain guide.





14. Remove the RH primary timing chain.





15. Remove the special tool from the RH cylinder head.





16. CAUTION: The flats on the camshaft must completely contact the special service tool or damage to the camshafts can occur. Slowly draw the special tool down evenly until it is fully seated on the camshaft flats.

Install the special tool on the LH head.





17. CAUTION: An open end wrench must be used on the flats of the camshaft or damage to the camshaft can occur.

Remove and discard the LH VCT unit bolt and the exhaust camshaft sprocket bolt.





18. Remove the LH timing chain tensioner.
1 Push the lever down and install a drill rod to lock the piston.
2 Remove the 2 bolts and the tensioner.





19. Remove the nut and the LH tensioner arm.





20. Remove the bolt and the LH timing chain guide.





21. Remove the LH primary timing chain.
22. Remove the crankshaft sprocket.





23. Collapse the RH secondary timing chain tensioner and install a pin to lock the piston.





24. Remove the RH VCT unit, exhaust camshaft sprocket and timing chain as an assembly.
25. Remove the 2 bolts and the RH secondary timing chain tensioner.





26. Collapse the LH secondary timing chain tensioner and install a pin to lock the piston.





27. Remove the LH VCT unit, exhaust camshaft sprocket and timing chain as an assembly.
28. Remove the 2 bolts and the LH secondary timing chain tensioner.

Installation
1. Install the LH secondary timing chain tensioner and 2 bolts.
^ Tighten to 11 Nm (8 ft. lbs.).





2. Install the LH VCT unit, exhaust camshaft sprocket and timing chain as an assembly.





3. Using new bolts, install the LH VCT unit and exhaust camshaft sprocket bolts finger tight.





4. Remove the locking pin from the LH secondary timing chain tensioner.
5. Install the RH secondary timing chain tensioner and 2 bolts.
^ Tighten to 11 Nm (8 ft. lbs.).





6. Install the RH VCT unit, exhaust camshaft sprocket and timing chain as an assembly.





7. Using new bolts, install the RH VCT unit and exhaust camshaft sprocket bolts finger tight.





8. Remove the locking pin from the RH secondary timing chain tensioner.





9. Reset the timing chain tensioners.
1 Hold the lever toward the tensioner piston.
2 Using finger pressure, compress the tensioner until it is completely collapsed.
3 Push the lever down and install a drill rod to lock the piston.





10. CAUTION: The camshaft holding tool should still be installed on the LH cylinder head. If the special tool was removed during camshaft removal, it must be reinstalled at this time.

CAUTION: The flats on the camshaft must completely contact the special service tool or damage to the camshafts can occur. Slowly draw the special tool down evenly until it is fully seated on the camshaft flats.

Install the special tool on the LH cylinder head.





11. Position the LH timing chain and crankshaft gear.
^ Position the timing chain over the LH intake camshaft sprocket.
^ Position the crankshaft gear in the timing chain.





12. Install the LH timing chain guide and bolt.
^ Tighten to 11 Nm (8 ft. lbs.).





13. Install the LH timing chain tensioner arm and nut.
^ Tighten to 11 Nm (8 ft. lbs.).





14. Install the LH timing chain tensioner and 2 bolts.
^ Tighten to 11 Nm (8 ft. lbs.).
^ Remove the drill rod.





15. CAUTION: The exhaust camshaft sprocket bolt must be fully tightened before tightening the intake camshaft sprocket bolt.

CAUTION: Using the special tool, apply 10 Nm (89 inch lbs.) counterclockwise to the LH exhaust camshaft sprocket.

Tighten the LH exhaust camshaft sprocket and VCT unit bolts in 2 stages:
^ Stage 1: Tighten to 35 Nm (26 ft. lbs.).
^ Stage 2: Tighten an additional 90 degrees.





16. Remove the special tool.





17. CAUTION: The flats on the camshaft must completely contact the special service tool or damage to the camshafts can occur. Slowly draw the special tool down evenly until it is fully seated on the camshaft flats.
