This is the procedure for a mechanical tensioner.

Removal

----------------------------------------------------------------------------------------------------------------

1. Remove front timing belt cover (Fig. 168).
2. Remove spark plugs.

CAUTION: Align camshaft and crankshaft timing marks before removing the timing belt by rotating the engine CLOCKWISE with the crankshaft

-----------------------------------------------------------------------------------------------------------------

Assemble

Set camshaft to TDC by aligning mark on sprocket with the arrow on the rear timing belt cover

1. Move crankshaft to 1/2 mark before TDC (Fig. 180) for belt installation.
2. Install the timing belt. Starting at the crankshaft, go around the water pump sprocket, then around the camshaft sprocket, and finally route the back side of the timing belt around the timing belt tensioner pulley
3. Move crankshaft sprocket to TDC to take up belt slack.

Rotate the crankshaft CLOCKWISE two complete revolutions manually for seating of the belt, until the crankshaft is repositioned at the TDC position. Verify that the camshaft and crankshaft timing marks are in proper position

1. Check if the spring tang is within the tolerance window (Fig. 182). If the spring tang is within the tolerance window, the installation process is complete and nothing further is required. If the spring tang is not within the tolerance window, repeat Steps 6 through 8.
2. Install front timing belt cover.
3. Install spark plugs.
4. Perform camshaft and crankshaft timing relearn procedure as follows:

• • Connect the DRB 1116 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.
  • Turn the ignition switch on.
  • Access "Engine" diagnostics.
  • Select "Miscellaneous" option.
  • Select "ReLearn Cam Crank" option and follow directions on DRB III screen

The following is for a hydraulic tensioner system

Removal

-----------------------------------------------------------------------------------------------------------------

CAUTION: DO NOT loosen, tighten, or remove the tensioner pivot bolt (Fig. 167).

1. Remove the timing belt from sprockets. CAUTION: Do not rotate the camshaft once the timing belt has been removed or damage to valve components may occur.
2. For timing belt tensioner pulley assembly removal Refer to TIMING BELT TENSIONER & PULLEY - REMOVAL

-----------------------------------------------------------------------------------------------------------------Installation

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

Set camshaft to TDC by aligning mark on sprocket with the arrow on the rear of timing belt cover

1. Rotate crankshaft 2 revolutions and check the alignment of the timing marks (Fig. 175) and (Fig. 174).
2. Check belt tension by installing pin into tensioner housing. If pin cannot be re-installed, repeat belt tension procedure.
3. Install the front timing belt cover.
4. Lower vehicle and perform camshaft and crankshaft timing relearn procedure as follows:

• • Connect the DRB III 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.
  • Turn the ignition switch on.
  • Access "Engine" diagnostics.
  • Select "Miscellaneous" option.
  • Select "ReLearn Cam Crank" option and follow directions on DRB III screen.
