yes, it is usually the Water Pump that fails, and takes the belt with it.
as mentioned, if you have Life Time powertrain waranty, it covers waterpump replacement IF IT IS LEAKING. Not sure if it'll pay for it as a Maintainence item, might want to check with chrysler.
If you didn't buy the car NEW, and don't have waranty, you should consider doing the WaterPump and Timing Belt as a 105k miles service in the Owner's manual. Because if it fails, your $1000 bill just rack up to $4000.
What did you went in for originally? why are they dissabling the front of the engine? 100K service usually is just Tune ups and some fluid flush/replacement.
