To adjust the belt on an Astra MK3, first ensure the engine is off and cool. Locate the tensioner pulley and use a wrench to relieve tension on the belt. Then, either tighten or loosen the adjustment bolt on the alternator or other accessory to achieve the desired belt tension. Finally, check the belt for proper alignment and tension before reassembling any components.
