Hello and thanks for using Just Answer.I will try my best to help you with your question.
You will have to remove the pulley on the power steering pump with a pulley remover tool, then remove the 3 bolts that hold the power steering pump to the bracket. Then remove the 2 nut on the studs for the alternator bracket. Then remove the 2 studs out of the bracket and the lower bracket bolt.
We use a stud remover to remove the studs. You can use the 2 nuts you removed by installing one nut on the stud, not all the way down, then place the other nut on the same stud and tighten it up to the other nut. Then use a wrench to remove the stud. Then repeat the process on the other stud.
It will be a little tight, but you can do it. You can remove the belt tensioner and alternator and the black metal brackets for it. It will be tight to get it out, but you can if you are patient.
You will need a Torx socket.
The size you will need is a T45 socket. Not the T55 in the picture.
This will take the bolt out of the tensioner to remove it.
