13. Lower the vehicle on the ramp.

14. Fit the camshaft locking tool 303 - 530 to the A-Bank
camshafts, aligning the shafts slightly as necessary.

15. Loosen the bolt which secures the sprocket to the camshaft.

16. Loosen the bolt which secure s VVT unit to the camshaft.
17. Remove the primary ch ain tensioner bolts.

Installation



2. Remove the tensioner blade.
