10. Remove the serpentine accessory drive belt.





11. Remove the crankshaft pulley bolts.
12. Remove the crankshaft pulley.
13. Remove the right engine mount bracket.
14. Remove the power steering hose clamp bolt, and position the hose clear of the repair area.





15. Remove the front timing belt cover bolts.
16. Remove the front timing belt cover.





17. Using the crankshaft gear bolt, rotate the crankshaft clockwise until the timing mark on the crankshaft gear is aligned with the notch at the bottom of the rear timing belt cover.

Notice: The camshaft gears must align with the notch on the valve cover or damage to the engine could result.





18. Align the camshaft gears with the notch on the valve cover.

Important: Use the intake gear mark for the intake camshaft gear and the exhaust gear mark for the exhaust camshaft gear since both gears are interchangeable.





19. Loosen the automatic tensioner bolt. Turn the hex key tab to relieve belt tension.
20. Remove the timing belt.
