I have a whistling noise from the belt area in my c3g engine with air condition, any help on how to remove the belt? Also what are the torque specifications for the wheel bolts or other bolts that are required to be removed in order to remove the belt?

Your best bet is to purchase the Revue Technique Automobile for your Twingo. Good book with plenty of diagrams, photos, etc. Only drawback is it's printed in French.
