The car should be turned off it should be cool.Then follow this procedure. Park the car on flat surface.Block the back wheels of the car from getting rolled because the front portion of the car has to be jacked up.But before doing that disconnect the black wire of battery.Its necessary for safety reasons.Then raise the car by placing jack under the cross-member.Then after this the passenger side wheel has to be removed.Once the passenger side wheel is removed you will see the belt.Locate the tensioner to remove the belt. The tensioner is located under the alternator. Loosen the bolt with a socket wrench and this will loosen tension on the belt. Take the belt off the alternator pulley and the air conditioner pulley. Unbolt and remove the tensioner to make proper space to remove the alternator. After that there are few more parts that are to be removed to remove the alternator.So remove the air conditioner ,its fitted by two bolts easily seen.Remove this bolts.No need to remove the ac wires or any ac lines.Just lift the ac unit out and then remove the alternator cable from its back.You will also have to remove a nut bolt holding the wire.So remove that nut also,this will help to loosen the alternator wire.Then carefully wiggle and pull the wiring harness to the voltage regulator at the back of the alternator.Now the alternator can be removed.But its connected to the mounting bracket.The alternator is fitted by 3 bolts on mounting bolts.Once you remove this bolts the alternator can be lifted out from the bottom of the car. -------------- This is the procedure to remove the alternator.But for no problem while fitting the new alternator,i suggest you mark the location of each part with marker so that you dont face any kind of problem while refitting this parts again.You can also take a picture of each part before removing it.so that will help for any kind of alternator problem in future also.Do it slowly ,carefully and at day time ,so this will give you exact access of the parts.---------------Thanks.Helpmech.
