What is the belt that goes to my alternator called? It needs replaced.

What is your question?

My alternator belt needs replaced. I am thinking that it's not called an alternator belt because that repair doesn't exist on your estimate program. The belt is cracked, very cracked. In fact, it looks as if it may break any day now. I would like an estimate to replace it, but I can't get that if I don't know what Subaru and/or the mechanics who repair such things call the thing.
