2001 Grand Caravan Timing Belt/Chain Questions

1) Does the 2001 GC have a timing belt or chain?
2) How frequently (if ever) should it be changed?
3) Are there any warning signs that it is about to go?

If you have the 3.3 or 3.8 engine it has a chain. I don't think there is a time/mileage interval for it. There is a slack check that can be done to it that involves removing the timing case cover. In my opinion, if a person has to remove the cover anyway and it has 100k+ miles, I would put on a chain. I did the chain and water pump about 120K or so. Had the cover off for a leak anyway or I would not had done it. By the way, taking off the cover also involves pulling the oil pan, new crank seal etc. if it is done by procedure.
