1. Remove alternator belt (see «Checking the tension of the alternator drive belt and replacing it»).
2. Disconnect the wire from the terminal «minus» battery.
3. Remove the right forward wheel and establish the car on a reliable support.
4. Remove the front timing belt cover and set the piston of the 1st cylinder to the TDC position (see «Setting the piston of the first cylinder to the TDC position of the compression stroke»).
5. Loosen the tensioner nut and turn the idler to loosen the timing belt.
6. Remove the timing belt from the camshaft pulley, idler pulley and water pump toothed pulley.
7. In order to unscrew the bolt securing the generator drive pulley, it is necessary to fix the crankshaft from turning. To do this, after removing the plug in the clutch housing, the assistant must use a mounting spatula or a large screwdriver to keep the crankshaft from turning by the teeth of the flywheel crown.
8. Having unscrewed the crankshaft pulley mounting bolt...
9.... remove it with a washer and remove the alternator drive pulley from the crankshaft.
10. Remove the timing belt from the crankshaft sprocket.
11. Before installing a new timing belt, clean the pulleys and tension roller from dirt and grease, degrease them with white spirit.
12. Install the timing belt on the car in the reverse order of removal. The alternator drive pulley can be installed in one position. The hole 1 of the alternator pulley must fall on the mounting sleeve 2.
13. When installing the timing belt, ensure the tension of its leading branch. After installing the timing belt, adjust the tension (see «Timing Belt Tension Adjustment (camshaft drive)»).
If noise is heard from the timing belt, it is likely that the tension roller bearing has failed. Remove the tension roller, check the performance of its bearing. If seizing, axial play, or noticeable leakage of grease from the bearing is felt when turning the bearing, replace the idler.
14. To replace the tension roller, before installing the timing belt, completely unscrew its fastening nut, remove the washer...
15.... and then the tension roller from the axle.
16. Establish on the car a new tension roller in an order, the return to removal. In this case, the holes for a special key should be directed outward. After installing the roller, adjust the belt tension (see «Timing Belt Tension Adjustment (camshaft drive)»).
