For more on marking an answer as the "Best Answer", please visit our FAQ.Not sure of the configuration on a Fiesta, but you have to slacken the screws on the alternator mountings in order that you can slip the new belt over all the pulleys, then with a hammer shaft, or similar, prise the alternator away from the block in order to tension the belt and re-tighten the mountings.
If you can't do this from above you'll need to put the car on ramps and work from below.
If you're not mechanically minded, ask a friend.
