Timing Belt Removal/Installation/Engine Timing

TIMING BELT REMOVAL

NOTE:
Left and right engine callouts are from the driver's seat.

1. Remove the timing belt covers in this order: right, left, then lower.





2. Loosen (don't remove) the tensioner pulley bolt.

3. Remove the idler pulley bolt, and let the idler pulley pivot towards the crankshaft timing pulley.

4. Remove the lower tensioner bolt and the tensioner pusher.

5. Carefully remove the timing belt from the pulleys.

ENGINE TIMING





1. Turn the crankshaft timing pulley until its notch aligns with the mark on the oil pump housing.

NOTE:
The crankshaft timing pulley may have a green mark 180 degrees from its keyway. Do not use this mark to set the crankshaft position.





2. Turn the right cylinder bank's camshaft pulley clockwise with a socket and ratchet. (The pulley clicks and stops several times.) Stop the pulley when its green mark aligns with the valve cover timing mark.

NOTE:
You may need to rotate the camshaft pulley up to four complete turns before its green mark aligns directly with the valve cover timing mark.





3. Turn the left cylinder bank's camshaft pulley clockwise with a socket and ratchet. (The pulley clicks and stops several times.) Stop the pulley when its green mark aligns with the timing belt cover bolt hole.

NOTE:
You may need to rotate the camshaft pulley up to four complete turns before its green mark aligns directly with the bolt hole.

4. Rotate the left cylinder bank's camshaft pulley clockwise another 1/4 turn to align its green mark with the valve cover timing mark.

TIMING BELT INSTALLATION

NOTE:
^ Do not install the timing belt until you are sure the camshafts, camshaft pulleys, and crankshaft timing pulley are in their correct "timed" positions.

^ Left and right engine callouts are from the driver's seat.





1. With the green direction arrows on the timing belt pointing clockwise, slip the belt over the right camshaft pulley so its solid white line (the line closest to the direction arrows) aligns with the mark on the pulley. Secure the belt to the pulley with a large binder clip.

2. Wrap the timing belt around the bottom of the water pump pulley, and draw it tight.





3. Slip the timing belt over the left camshaft pulley so its other solid white line (the one farthest from the direction arrows) aligns with the mark on the pulley. Secure the belt to the pulley with a large binder clip.





4. Wrap the timing belt around the inner side of the idler pulley, then slip the belt over the crankshaft timing pulley with its dotted white line aligned with the green mark on the crankshaft timing pulley.

NOTE:
For correct belt stretch, the dotted line must meet the green mark on the crankshaft timing pulley at the 9 o'clock position. If there isn't enough slack to slip the belt over the pulley in the correct position, turn the crankshaft a few degrees counterclockwise, install the belt, then turn the crankshaft back to the 9 o'clock position.





5. Place the tensioner pusher in a soft-jawed vise, then slowly compress the tensioner pusher pin until it lines up with the two small holes in the tensioner pusher housing.

6. Insert a straightened heavy duty paper clip through the holes in the housing. This will hold the pin in its compressed position.

NOTE:
A new tensioner pusher comes with its pin held compressed by a special wire. If you install a new tensioner pusher, save the wire for future use.





7. Install the tensioner pusher:

^ Install the lower bolt loosely.

^ Push the tensioner pusher up against the tensioner pulley, then install the upper bolt, and torque it to 25 N.m (18 lb-ft).

^ Torque the lower bolt to 25 N.m (18 lb-ft).

8. Remove the wire or paper clip from the tensioner pusher, and remove the binder clips from the camshaft pulleys.

9. Verify the timing belt is correctly installed:

^ Rotate the crankshaft three complete turns (not two turns, as stated in the service manual).

^ Align the crankshaft timing pulley notch with the mark on the oil pump housing.

^ Check the green marks on both camshaft pulleys; they should line up with the valve cover timing marks.





NOTE:
After you rotate the crankshaft, the solid white lines on the belt will not align with the camshaft pulley marks; this is normal.

10. Remove the crankshaft bolt, then install the lower, the right, and the left timing belt covers. Torque the cover bolts to 19 N.m (14 lb-ft).

11. Install the crankshaft pulley, and torque the bolt to 167 N.m (123 lb-ft).

12. Install any other parts you removed to replace the timing belt.
