i'm working on puting the head back on my 95 contour zetec, and i read on one of the forums that some kind of tensioner spring is used when replacing the timing belt, my 'tour doesnt seem to have this spring for the belt, and i cant seem to order it at a parts store without ordering the whole belt tensioner assembley (all i need is the spring and the bolt), does anyone know the part number, or if i'm just telling the parts guy the wrong name for the part(belt tensioner, sound right?).
