does a 2002 pt cruiser touring edition have a timing chain or a timing belt?

I've been told that if a car has a timing belt, it needs to be replaced at certain intervals. If a car has a timing chain, it doesn't need to be replaced as often. Does a 2002 touring edition pt cruiser come equipped with a timing chain or a timing belt? If it has a belt, how often does it need to be replaced?
