They are self tightening.... check and make sure that the tensioner pulley hasn't broken the big spring inside of it.... if the pulley is still doing it's thing, than the belt has streched over time and needs to be replaced

Replacing alternator belt on 2007 1.3 cdti combo is it easy to do

Loosen alternator, push it towards the block until belt is loose. Pull the belt off and replace. Once the new belt is on push the alternator away from the block until belt is tight and tighten bolt/bolts. You might need a bar to keep tension on the alternator while tightening bolt/bolts.

How to tighten the altanator belt on a 1983 chevy cavalier

It's alternator. Do you have a serpentine belt or seperate belt. If seperate, there are two bults on the alternator. Loosten both but do not remove. Take a prybar and pry back on alternator. Have someone hold the prybar while you tighten or hold yourself and tighten. If you have a serpentine belt, you need to replace the belt tensioner. The spring is weak inside the tensioner. It's 30 years old. remember that.

The serpentine belt on a 2.4L is VERY loose after alternator replacement. Can I tighten it or is the tensioner or belt dead?

I think you are on the right track, suspecting the tensioner. It should spring back after you release it. There is a pretty heavy spring inside, it may have broken.

Serpentine belt tensioner will not tighten

If the tensioner will not keep the belt tight then the tensioner is bad and will need to be replaced. The spring on the inside will loose it's tension over time.
