its pretty straight forward - all you have to do is loosen the nuts on the alternator and take up the slack and then re-tighten the nuts. A rough guide as to how tight it should be is you should just be able to twist the belt 90 degrees. Probably a good idea to check the condition of the belt while your at it.
well prob a bit more than 5mins but shouldn\'t take more than 30mins - it really is as simple as loosening the alternator bolts pushing it back to take up slack and then tightening it back up
