Here is how you check, start your car and have the radiator cap off, make sure the coolant level is full..... after the car warms up and the thermostat open you should see the coolant flowng through the radiator.... if the coolant dosent move at all, either your waterpump is bad or the thermostat is tuck closed, if your car overheats then the thermostat is stuck closed, if it dosent overheat than the waterpump is bad.
How do I know the water pump in my 85 olds is not working ? Have changed the radiator %26amp; hoses and still leaks?
make sure the fan belt is spinning the water pump.

Water will leak out of the bottom of a water pump thru what is call a weap hole.Take a flashlight crawl under the water pump area an see if you see water leaking from the underside of the pump..Do this with the engine off of course
