Replaced the water pump on our '97 Buick Century because we thought that is where the leak was originating. Replaced the hose from the radiator to the water pump as well. It is still leaking with fluid gathering on the thermostat housing. Is it possible that the thermostat housing could be the spot it is leaking from? The tempurature runs at normal with the low coolant light coming on to alert needing to add coolant if it is not checked every couple of days.

What is the question?
Either a hose leaks or the radiator
needs to be replaced

Whenever I see a system which is leaking from more than one or two places, I do a head gasket check because that tells me that the system is experiencing above normal pressures. the wet floor is a heater core. whether it's a water pump or some other thing near it only you can tell. Actually it rarely happens, but the wet floor could be the hose where it meets the heater core at the firewall; again, only you will be able to tell the difference. if the hose connection looks dry, assume that it is the core itself.

Best way and safe to check coolant leak. Use or you can rent one from
auto part store. "Radiator pump presure tester"
Let the engine cold down and hook it to radiator filler neck make sure it's good tight then pum untill you feel some presure, then it time to check for leak. You'll be able to see water comes out.

i would check the radiator for flow...sounds like it is plugged with something...good luck...lee

The water pump is next to front right wheel, so if it is leaking around there chances are that it is the water pump...try checking the radiator by flushing water through it and checking for leaks, if not well then it has to be the water pump.

Have someone pressure test the cooling system - you likely have a head gasket leak

is it water or coolant, and do you have water in the radiator or antifreeze, i asume you have coolant so the leak is water then it coming from the heater box which is normal, the water is condensation from a/c so if the a/c is on or defrost you will get water drain out this is normal operation.hope this is helpful.

Could be a hose..
When you pull into your drive way - when it is hot - shut it off - this is the best time to look for the leaks because after you shut it of the presure builds a bit.. Check the hoses..
Could be the water pump...
ould be a freeze plug gone bad..

Good luck !

Check your heater hoses. It sounds like your leak is a hose.
