Fan belt? No such belt on this car, it does however have two aux. drive belts, one for the alternator and one for the power steering pump(sometimes this includes air-con where applicable).
Which of your belts needs replacing?
If its the alternator belt, I'd personally replace them both as you need to remove the p/steering belt to get to it. I always replace any drive belts once they have been disturbed, small cost compared to the hassle of replacing them again/later.
