1. Park your Taurus on level ground and apply the parking brake. Turn the engine off and allow it to cool down.
2. Open the hood of your car and locate the alternator belt. The belt is usually located on the front of the engine, near the top. It is a long, black belt that runs around several pulleys.
3. Locate the alternator adjustment bolt. The bolt is usually located on the side of the alternator, near the top. It is a long, thin bolt with a nut on the end.
4. Use a wrench to loosen the nut on the alternator adjustment bolt. Do not completely remove the nut.
5. Use another wrench to turn the alternator adjustment bolt clockwise. This will tighten the alternator belt.
6. Tighten the nut on the alternator adjustment bolt.
7. Start the engine and let it run for a few minutes. Check the tension of the alternator belt. The belt should be snug, but not too tight. If the belt is too tight, it could damage the alternator.
8. If necessary, repeat steps 4-7 until the alternator belt is properly tensioned.
9. Close the hood of your car.
That is how to tighten the alternator belt on a 1995 Ford Taurus.
