When should you replace the timing belt? on 2001 Chrysler Town & Country

I just bought this vehicle and it seems in very good condition although I am not sure the maintenance that has been done. It has 117,000 miles and the car fax does not offer a lot of info about this vehicles history.

I'm unable to look that up, is it a 4 or 6 cylinder engine?

I believe they only put the 4.0L V6 in these vans that year and if yours is the engine it is recommended at 100,000 miles
