I had to do this about a year ago, and it was actually very simple. If you go out and buy an alternator, there are basic directions of what to do, and also having a Haynes manual to fill in the gaps will get you there. I know very little about car repair/maintenance and was able to do this mainly by myself (you might want another person to add some muscle for getting some parts off). even easier, make sure you have the appropriate wrenches, disconnect your battery before doing any work, you can shock yourself... disconnect wires from the alternator, use a wrench on the bolt to losen the belt (follow the belt to the passenger side, it's the next one, now go down about 4-5 inches) remove belt off of alternator, now it's just two bolts on the alternator to take out and you're good to put the new one in... just reverse the process for putting the new one in... i did mine last week... this is exactly how it happened... took about 20 minutes maybe
