Hi,not sure on your model,but on the 1.3 multijet it has a stretch belt with no adjustment/tensioner,if removed and obviously stretched to get off, can if reused come off after a period of time as tension is incorrect,so if this is the type of belt is fitted I would reccomend new asap,as although the belt can visually appear fine,being stretched it is liable to come off. Think belt drives power steering as well,hope this of help,John
