Alfa Romeo 147 1.9 jtd 8V Instructions for changing the timing belt

Hello, maybe someone can help me further, I am looking for a guide to the timing belt change for an Alfa 147 1,9 jtd 8V. I have already searched everything here and unfortunately find no good post where not immediately will be deviated from the topic. It would also be helpful if someone could call me the list of the required special tools or the making for it. I hope someone can help me. Ps: yes I am from the subject but unfortunately no Alfa screwdriver, and yes I make the water pump with new.
