loosen the bolt that is holding the adjuster of the alternator. loosen the belt by pulling it and the alternator would slide in. remove and replace the belt.
do the reverse on installation.
remember to tighten all bolts of the adjuster and alternator after tightening the belt.

THE AIR FLOW METER IS LOCATED BESIDE THE AIR FILTER HOUSING.
IF YOU ARE GET IT A CHECK ENGINE LIGHT FOR RICH OR LEAN FUEL MIXTURE THE AIR FLOW METER IS THE MOST LIKLY AT FAULT.
AIR /FUEL RATIO SENSORS ARE THE SENSORS BEFORE THE CAT IN MOST NEWER CARS
I DON'T THINK THAT YEAR USES A TRUE A/F SENSOR BUT RATHER A O2 SENSOR.

SOURCE: My name is Shawn and
P0171 means Fuel Trim System Lean (Bank 1)
The MAF (Mass Air Flow) Sensor is dirty or faulty.
Note: The use of "oiled" air filters (K&N, etc.) can cause the MAF to become dirty if the filter is over-oiled
There could be a vacuum leak downstream of the MAF sensor.
If your FT is leaning it that much, I would suspect an O2 sensor or it's circuit is the problem. When that O2 sensor went to 2V, I think you found your problem. The O2S is telling the PCM that the fuel ratio is way rich, so the PCM is assigning a way lean fuel trim.
Replacing the Mass Air Flow Sensor should do the trick.
