COOLANT LEAK

1981 Ford F-150 • 90,008 miles

I have replaced my radiator, radiator hoses, heater core and hoses, thermostat, and poured in new coolant and it looks like the bottom of the water pump leaks only when I let it sit over night. Before I replaced the heater core coolant would come out of the firewall and leak out on the passenger side floor in the cab after I replaced the heater core the only leak was the heater box in the cab so I have it disconnected from the water pump at the moment. I don't have a clue what else to do besides replace the water pump and I need a heater since it gets cold up here in the winter.
