,belts can be a twat to refit once off,they are under tension by the tensioner which is spring loaded,you will see this at top of your engine to the left,easier way to refit is as stated above getting as much as possible around your last pully useually your crank pully,it is much easier with someone helping with them pushing the tensioner down to give you more slack,its a short cut that works,i did it solo and it was very tight,like i said do a good map to how it fits,as for when its off its big and could hold bridget jones knickers up twice,dont do this unless your sure you can refit it as you will be off the road until refited,
