Peugeot 406 TD Alternator Change

Hello friends, I have to change the alternator's tension strap
you can get a manual or explain how I can do it,
thank you

Hi, friend; It is very easy to change this strap; This vehicle carries a dynamic tensioner, if I am not mistaken, it carries an Allen Number 9 head, you remove it and it will come out although it costs it a little, and again the new ones, you have to have the precaution of mounting the dynamic tensioner well in position and shape, that is, since when you start the engine the belt will expel it.

Information was very useful since I changed it successfully.
Thank you so much
