2002 Dodge Caravan water pump

My van is leaking water/antifreeze after being drove for about 10 to 15 miles, dosent leak when setting, I replaced the thermostat, thought maybe it was stuck open, replaced the radiator cap to assure the correct pressure, water is circulating in the radiator, so on that note I am baginning to think maybey the weep hole on the water pump is leaking. What would be your opinion and if it is the water pump is the pump an easy access or is it behind the timming belt and eveything else. Thank you
