cam belt change
there are special tools but its posible to do without them if you are carfull .....the cover on the belt is held on with rib tool fixings they will normal be taken off with torx tools be carefull not to break the cover ,the pully on the crank is much the same ,the altinator drive belt has an auto tensioner thats very strong use a long spanner (15mm)and leave it on against the subframe you wont get it on easily once you take it of if you do take it off ,rotate the engine(clockwise) to top dead center and mark the pullys top and bottom with paint so you have reference marks slacken the tensioner on the cam belt and remove the belt putting the new one on to realign the marks on the sprockets to retension the belt use a large screwdriver put it in the hole in the casing at the right hand side of the tensioner and push against the metal bracket that holds the bearing assembly and push the tensioner into the belt till the small arrow lifts up past the hole drilled in the bracket ,tighten up the 13mm nut that holds the tensioner and rotate the engine(clockwise) two turns then retension the tensioner so the arrow ligns up with the hole in the bracket.dont try and start the engine till you are sure that everything has lined up propely
