The engine uses a single cam belt drive system with a serpentine type belt. The left side of the engine uses a hydraulic cam belt tensioner which is self-adjusting.

It is recommended that the timing belt be replaced every 60,000 miles (96,618 km).

1. Disconnect the negative battery cable.

2. Position the No. 1 piston to TDC of its compression stroke.

3. Remove the engine drive belts.

4. Remove the timing belt covers.

5. Align the camshaft sprockets so each sprocket notch aligns with the cam cover notches. Align the crankshaft sprocket top tooth notch, located at the rear of the tooth, with the notch on the crank angle sensor boss. Mark the three alignment points as well as the direction of cam belt rotation.

6. Loosen the tensioner adjusting bolts. Remove the bottom three idlers, the cam belt and the cam belt tensioner. The cam sprockets can then be removed with a modified camshaft sprocket wrench tool.

7. Remove the sprockets, if necessary. Note the reference sensor at the rear of the left cam sprocket.



To install:

8. Install the sprockets, if removed and torque the retaining bolts to 47-54 ft. lbs. (64-74 Nm).

9. Install the crankshaft sprocket and the non-adjustable right side idler. Do not install the tensioner idler at this time.

10. Compress the hydraulic tensioner in a vise slowly and temporarily secure the plunger with a pin or suitable Allen wrench. Install the tensioner and the pulley with the adjustable idler pulley. Temporarily tighten the tensioner while the tensioner is pushed to the right.

11. Align the crankshaft sprocket notch on the rear sprocket tooth with the crank angle sensor boss. This places the sprocket notch in the 12 o'clock position.

12. Align the camshaft sprockets with the notches in the cam rear belt cover. This places the sprocket notch in the 12 o'clock position for each camshaft.

13. Install the timing belt with the directional mark and alignment marks properly positioned (if belt was reused).

14. Loosen the tensioner retaining bolts and slide the tensioner to the left. Tighten the mounting bolts.

15. After verifying the timing marks are correct, remove the stopper pin from the tensioner.

16. Verify the correctness of the timing by noting that the notches on the 2 cam pulleys and the notch on the crankshaft pulley all point to the 12 o'clock position when the belt is properly installed.

17. Complete the engine component assembly by installing the cam belt covers, the crankshaft pulley bolt and pulley and the remaining components.

18. Connect the negative battery cable.
