Coolant dripping under thermostat housing not sure exactly where it's coming from could I need a water pump. Will overheat in less than 4 miles. Happens when I drive it

Water pump failures are not uncommon on these vehicles with age and miles. Replacing the radiator cap may have done a good job of pressurizing your cooling system properly -- but in turn may have exposed weakness. Good luck.
