This relieves the tension from the belt and you can now pull it off of the alternator and out of the way while holding down the tensioner.
Step4: Remove alternator
-Using your 16mm, remove the upper and lower alternator bolts (see pics below for bolt location)
-Using a 6mm allen bit socket, remove the oil hard lines as seen in the picture below. (be sure to have a rag handy, a small amount of oil will come out when removed.
-Using your 17mm socket you can now remove the rear positive terminal.
-The negative terminal on the rear of the alternator is a wire clip. see picture to identify and remove.
-You can now pull your alternator off. It may require you to use your flat-head screw driver to help pry the arm from the lower bolt housing on the car
Be sure to line up the idler pulley correctly when re-installing. There is a guide located in the picture below that should be in place.
