1. The generator drive belt connects it to the crankshaft pulley.
2. Correct tension of the drive belt will ensure its long and reliable operation. If the belt is too tight, the alternator can wear out quickly.
3. The belt should be inspected regularly. If it is found to be too tight, worn, frayed or cracked, it should be replaced. We recommend that you always have a spare alternator drive belt in your car, just in case.
4. To remove the old belt, loosen the generator mounting bolts and nuts enough to allow the generator to be rotated toward the engine. Due to this, the tension will be relieved from the belt, which can now be removed from the pulleys. Install a new belt, remove any slack by turning the generator into place, and secure the generator with the bolts without fully tightening them. Please note that on power steering models, you will have to first remove the power steering pump drive belt before removing the alternator belt (see chapter 8, section 14). Be sure to reinstall it after installing the alternator drive belt.
5. There are special devices for checking belt tension, but you can do without them. The belt is considered to be well tensioned if, when pressed with your thumb at the midpoint of its longest run, the deflection is 13 mm. Adjust the position of the generator to achieve the desired tension and tighten the generator bolts. When turning the generator, you should apply the load to its support bracket and in no case to the free end of the generator, because this may cause serious internal damage to it.
6. After installing the new belt, start the engine and after 5 minutes check the belt tension again and adjust it if necessary, because The belt may stretch slightly.
