The issues are very different. Water pumps fail because they start leaking through the front seal. The plugged or non functioning thermostat fails by causing serious overheating of your engine. If it fails open, you get little heat.
Radiators start getting old and you will see that they seem to be ok in cool weather but on warmer days you find the car runs warm. Removing the thermostat does not resolve this issue.
The main purpose of a thermostat is to get quicker heat in your car. Most cars will run with on thermostat installed. If your car still is getting warm, it is a good chance your radiator is plugged.
Water pumps almost never fail in any mode other then leaking. If you take the thermostat out and start your car, you should see coolant movement. If you do, the pump is fine.

How do you tell if Chevy impala water pump is leaking?
If there is coolant coming from it and it isn't a hose.
How can I tell if a water pump is bad on a ford Truck?
Wait until the thermostat opens , so the top radiator hose is hot , then squeeze the radiator hose and then stop squeezing - if the water pump is working you will feel a surge of coolant through the hose if the impeller inside the water pump is fine ( I'm assuming that there is no squealing sound or coolant leaking from the weep hole of the water pump )
How do you tell a bad water pump?
Top hose of radiator is hot and engine is still over heating usually.
How can you tell if your water pump bad?
besides making a sqeeling noise , or leaking from the weep hole , you can wait until the thermostat is open ( top radiator hose will be HOT ) and squeeze the top radiator hose , when you stop squeezing the hose if there is no surge of coolant flowing through the hose then your water pump is not actually circulating your coolant and has a bad impeller inside the water pump
How do you tell if water pump is working 1991 Crown Victoria 5.0?
I'm not a mechanic / technician but the way that I tell the water pump is working is : I wait until the engine thermostat is open ( the top radiator hose is hot ) and without catching anything in a moving belt I gently squeeze the top radiator hose and then release it slightly , you should feel a engine coolant surge
How can you tell if your water pump go bad?
I presume you mean car water pump? If the water pump is faulty the car will over heat and the temperature gauge will go up. Make sure that there is enough coolant in the radiator, the radiator or the hose pipe is not leaking and the radiator cap is not faulty, as all of these faults can cause overheating. Once you have excluded these then you can blame the water pump.

My Mercury 50 hp outboard engine with a new water pump will not pump water?
The first check would be to ensure that the tell tale hose is open. Dirt daubers are notorious for crawling up in the hose to build their nest. If you have access to an air compressor, try shooting a short blast of air through the hose. Another method that works is to slide a short length of wire up the hose, in an attempt to unplug it. If the hose is not clogged, the lower unit should be removed for further diagnosis. Make sure that the water tube seal, located in the pump housing, is serviceable. Sometimes when the foot is installed, the tube is not properly inserted, or missed altogether. While the foot is off, blow air, or run water through the water tube to insure that there are no other blockages.
What would you use to make a Girl into a Water Balloon?
Hose and you tell a Girl to put her mouth on the end of the hose and when her mouth is on the hose you sticky tape around it and then when you are finished take a photo of the girl with a hose in her mouth and then you turn on the hose and all the water will pour into her body and she will be a Water Balloon.
How can you tell if antifreeze leak is caused by the water pump?
I am sure you have a v8 engine----if so the water pump weep hole will leak antifreeze and show up running down the lower rad hose on the water pump side ---of course there are other places antifreeze can leak at the front of the engine such as the water pump mounting gasket----the lower left (drivers side) p ump mounting bolt---as it enters the water jacket--- the timing caver gasket and the intake manifold gasket but the pump is the most likely place
