With Mechanical Tensioner

REMOVAL

CAUTION: Camshaft or crankshaft should not be rotated after timing belt is removed. Damage to valve components may occur. Always align timing marks before removing timing belt.

1. Remove accessory drive belts.
2. Raise vehicle on hoist and remove right inner splash shield.
3. Remove crankshaft damper bolt.
4. Lower vehicle.
6. Support engine with a jack and remove right engine mount.
6. Remove power steering pump assembly and set aside.

Front Timing Belt Cover:





7. Remove engine mount bracket and timing belt cover fasteners, remove cover.

CAUTION: Align camshaft and crankshaft timing marks before removing the timing belt by rotating the engine with the crankshaft. Do not rotate the camshaft once the timing belt has been removed as damage to valve components may occur.

Timing Belt-Removal:





8. Align camshaft timing marks and crankshaft timing mark with arrow on oil pump housing.
9. Install a 8 mm Allen wrench into the timing belt tensioner. Insert the long end of a 1/8 inch or 3 mm Allen wrench into the pin hole on the front of the tensioner.
10. Rotate the tensioner counterclockwise with the Allen wrench, while pushing in lightly on the 1/8 inch or 3 mm Allen wrench, until it slides into the locking hole.
11. Remove timing belt.

INSTALLATION

Crankshaft Sprocket Timing:





1. Set crankshaft sprocket to TDC by aligning the sprocket with the arrow on the oil pump housing, then back off to 3 notches before TDC.

Camshaft Timing Marks:





2. Set camshafts timing marks together by aligning notches on sprockets.

Adjusting Crankshaft Sprocket For Timing Belt Installation:





3. Rotate crankshaft 1/2 tooth counterclockwise from TDC.

Timing Mark Alignment:





4. Install timing belt in this direction. Starting at the crankshaft, go around the water pump sprocket, idler pulley, camshaft sprockets and then around the tensioner pulley.
5. Move crankshaft sprocket to TDC to take up belt slack.
6. Release the tensioner by removing the pin or Allen wrench from the belt tensioner.
7. Rotate crankshaft 2 revolutions and check the alignment of the timing marks.
8. Install front half of timing cover.
9. Install engine mount bracket.
10. Install power steering pump assembly.
11. Install right engine mount.
12. Remove jack from under engine.

Crankshaft Damper-Installation:





13. Install crankshaft damper using M12 1.75 x 150 mm bolt, washer, thrust bearing and nut from Special Tool 6792. Install crankshaft damper bolt and tighten to 142 Nm (105 ft. lbs.).
14. Install accessory drive belts.
15. Raise vehicle on hoist and install right inner splash shield.
16. Lower vehicle and perform camshaft and crankshaft timing relearn procedure as follows:
- Step 1: Connect the DRB scan tool to the data link (diagnostic) connector. This connector is located in the passenger compartment; at the lower edge of instrument panel; near the steering column.
- Step 2: Turn the ignition switch on and access the "miscellaneous" screen.
- Step 3: Select re-learn cam/crank option and follow directions on DRB screen.
