I just replaced the serpentine belt on my 1996 Ford Contour. I opted to remove the front passenger-side tire to gain access to the tensioner. Once I was able to get to the tensioner pulley, I had the old belt off and replaced within 10 minutes. I did have some help, though. It is much easier to have one person release the tension while another puts the new belt into place.

No, you do not have to remove it. It is also possible to release the tensioner top-side. I once had a tensioner go bad in the parking lot at work and had to replace it there with what I had in my trunk. It is easier with the tire off, but if you have to a slim ratchet with a shallow socket should do the trick.
Check to make sure the belt is routed around the compressor pulley. Also check the wiring connector at the compressor in case it was dislodged.
No. The serpentine belt controls A/C, alternator, water pump, power steering pump, and that is it. And if the belt is replaced properly, it will not cause damage to anything.
The Tensioner is spring loaded-use a long wrench on the center of the pulley 2 release tension-DON"T UNBOLT anything-IF it doesn't feel springy then find the bolt in the center of a (the) pulley that is.
No, they usually can stretch slightly if anything but the tensioner should take up the slack if they do. If you took it off and when you go to put it back on it's too short you have routed it incorrectly.
check the belt tensioner. the belt is used to activate things like your A.C., alternator and other things. the tensioner takes up the slack on the belt after its installed. it dosent DO anything except take up the belt slack.
You don't. The serpentine belt tension is automatically maintained by the tensioner pulley, which is an idler pulley located on the passenger side of the system and looks like it doesn't drive anything. If the belt tension is incorrect, the tensioner pulley must be replaced. If the question meant 'how to release tension from the belt' (for removal, etc.), this is done by applying the correct size socket wrench to the tensioner pulley's center nut and rocking the pulley away from the belt.
You should be able to get at it with one of the special tools available at most auto parts stores - they are inexpensive, and look like a long, flat piece of metal with a 1/2" square drive on one end to engage the idler arm.
It is the same assembly as the tensioner pulley - the little pulley that isn't attached to anything.
if the 2000 is anything like the 99, the alternator is on the top in the front. Very easy to find. Pull of the serpentine belt (use the tensioner to help) and then you remove the electrical connections very simply. UUndo the three bolts connecting it, pull it off. Do the reverse to put the new one on...and slap the serpentine belt back on. Very easy process..hardest part was the belt, but you can do it.
Open the hood. Now look at all the pulleys. The one that is not connected to any component and is not driving anything, is the idler tensioner pulley.
No specific problems other than it's pretty easy to install incorrectly which will ruin them pretty quickly. Also check the pulley on the tensioner. If the pulley is worn or doesn't turn freely, that will cause premature wear on anything with a serpentine belt. Good luck.
first you need to be sure you know how the old one is routed, either by the diagram near the radiator or by making your own. there is an "inside" and an "outside" to the belt. next locate the tensioner pulley. its usually attached to the alternator. its the only pulley that isn't attached to/drive anything. put a wrench on the tensioner and slack the belt. remove the old one. compare it to the new one to be certain its the correct replacement. rout the new belt around all the pulleys making sure to insert the belt onto the tensioner last because you will have to slack the tensioner to get the belt on. pay attention to the way the belt "faces" each pulley.
