In this video we can see how to change the alternator elastic belt on a Ford Fiesta with a 1.25 engine. We remove the bolts from the alternator: this removes most of the tension, and helps a lot when we put the elastic belt back on. Now we remove the belt from the water pump, and slide it off. We remove the two 20 torx screws underneath.

To mount the new belt on the pulleys, a specific tool is needed, or we can loosen another bolt located under the alternator, so that, moving it back and forth, it is not necessary to use a specific tool, but only a wrench and a ratchet. Once the belt is reassembled, we tighten the tension pulley clockwise.

We may need to pull the belt under the water pump and move it back and forth until it fits correctly. Using a pry bar, we push the alternator inwards, and align the bolts from all sides, without tightening them too much, then we do a few test runs.
