how hard is it to change an alternator on astra van? ?

remove o/s inner wing shield,remove fan belt,two bolts holding it on plus main cable lead and push in connector,remember and disconnect battery,if you are buying a new or reconditioned one then the vacuum pump comes with it so disconnect all pipes etc regarding that or if it comes with no vacuum pump then there are three slotted screws holding it onto the alternator,think the horn needs to be removed to remove,good luck
