Removing
30. Follow the steps in steps 1 and 2 if you have not already done so.
31. Disconnect the wire «masses» from battery (refer to paragraph «Disconnecting the battery»).
32. If necessary, remove the screws from the power steering pump pulley shield and remove the shield to gain access to the top of the drive belt.
33. Working from under the wheel arch, loosen the bolt located in the center of the eccentric idler pulley.
34. Insert a bent square rod with a side of 7.0 mm (e.g., a quarter-inch square socket extension) into the square hole on the face of the eccentric idler.
35. Use a pin to rotate the eccentric idler pulley until the hole in the auto tensioner pulley arm is aligned with the hole in the rear support bracket. When the holes are aligned, insert a suitable adjustment tool (bolt or bent rod with a diameter of approximately 8.0 mm) through the hole in the lever and in the support bracket.
36. With the auto-tensioner locked, rotate the eccentric idler wheel just enough to give the belt enough slack to remove the belt, and then remove the belt from the pulleys (fig.12.21).
Note. If the belt is to be reused, mark the direction of rotation on the belt before removing it. This will ensure that the belt is installed correctly.
Installation and tension
37. When replacing a belt, make sure that the new belt is of the correct type, and if a removed belt is being installed, follow the marks made during removal to install it correctly. Slide the belt over the pulleys so that the ribs of the belt fit correctly into the grooves on the pulleys and the belt is routed properly.
38. Turn the eccentric idler to tension the drive belt just enough to take the load off the adjusting toohpout changing the position of the eccentric idler, securely tighten the appropriate bolt.
39. Remove the adjusting tool from the auto-tensioner arm, and then rotate the crankshaft four full turns in the normal direction of rotation.
40. Check that the holes in the auto adjuster arm and in the support bracket are still aligned by reinserting the adjustment tool. If the bolt does not go in easily, repeat the tightening procedure from step 38.
41. Finally, connect the wire «masses» to the battery and all other disturbed elements.
