we replaced the alternator, and checked the belt. Did not need to replace the belt, but the belt is loose on the pulleys, and is not turning when we start the engine. We just need to figure out how to tighten the belt.

Sounds like your tensioner is broken. I attached the process on how to do this.

You have what is called an auto tensioner which means it is spring loaded and when you release it, all the tension in the belt is taken out.

The other possible cause is you routed the belt wrong. I attached that as well so you can make sure it is going the correct direction around the pulleys.

Let us know what you find. Thanks
