fluid leak

probly not the water pump is under the cover on the passenger side of the car if im remembering right and they didnt change too much into the late 90's than you should look more at the thermostat housing and bypas hoses

probably a bad hose. just pop the hood and it shouldnt be too hard to spot where the leak is from

Check that your cooling system really is loosing water and that it's not just condensation from the aircon
