Question about 2000 Chevrolet Impala
The alternator and belt tensioner have both been replaced and the belt is off about 1/4 inch.
I think that you've either had the wrong replacement parts installed, the wrong belt or could be missing a spacer somewhere causing your belts not to align. Also you could have another pulley or pump needing replacement or just simply the replacements were not installed correctly along with their bracketts. There is a more serious outcome if everything has been done correctly but lets not go there yet.

Turn off the engine and place the transmission in park (automatic) or first gear (manual). Engage the parking brake and open the hood. Disconnect the negative cable from the battery terminal using the battery terminal wrench.
Remove the serpentine belt by inserting the end of the serpentine belt tool into the square hole on the belt tensioner and rotating the removal tool clockwise. Unplug the alternator's electrical connector. Remove the bolt holding the positive voltage cable to the alternator using a 3/8-inch ratchet and a metric socket. Remove the positive voltage cable from the alternator.
Remove the alternator bracket bolts using a metric socket connected to a 3/8-inch ratchet. Remove the alternator from the car. Place the new alternator in the mounting brackets and reinstall the mounting bolts using a 3/8-inch ratchet connected to a metric socket.
Reinstall the positive voltage cable on the alternator and tighten the retaining nut using a 3/8-inch ratchet and a metric socket. Plug in the alternator's electrical connector. Compress the serpentine belt tensioner using the serpentine belt tool. Reinstall the serpentine belt according to the belt-routing diagram located under the hood.
Reconnect the negative cable to the battery using the battery terminal wrench. Start the engine and verify that the alternator works.

Locate the two belts on the left side (passenger side) of your Mitsubishi Lancer. The outer belt is a serpentine belt, operating four pulleys and the inner belt is your alternator belt.
Follow the serpentine (outer) belt to the three pulleys lined up vertically near the front of the engine compartment. Locate the middle pulley, which is the tension pulley for the belt.
Loosen the bolt on the middle pulley with a socket wrench by turning counter-clockwise. Do not remove the bolt, just turn it a couple of times. Loosen the tensioner bolt on the side of the of the pulley, facing the front of the vehicle.
Remove the serpentine belt and then loosen the bolt on the alternator. With the alternator loose, move it forward so that the alternator belt loosens up and then remove belt from the pulleys.
Install the new alternator belt by placing it over both inside pulleys. Tighten the tension on the alternator belt by moving the alternator back and keeping tension on it by holding it back with a long screwdriver. While the alternator belt is tight, use a socket wrench to tighten up the bolt on the alternator.
Place the serpentine belt back on the pulleys and then use a socket wrench on the bolt on the front of the tension pulley. Once the serpentine belt is tight, tighten up the bolt in the middle of the tension pulley.
Start the Mitsubishi Lancer's engine to test the alternator belt and make sure it is working properly. Once you have verified it is working, turn the engine off.
