How can I tell if my water pump is working, or if it is just the thermostat? The top radiator hose is real soft and no circulation
that I can see after running about 20 minutes.

If your water pump it not working I would assume you would hear the bearings screaming or you would have water loss from the pee hole. Best thing to do to start with (and cheapest) is change the T-stat or at least remove it and drop it into a pot of boiling water to see if it opens. What temperature T-stat are you running, how old is it, does your car over-heat at all or are you checking it after idling in the drive way after 20 minutes? Have you tried to purge your system to make sure that you do not have an air lock? The more experienced guys on here will be able to help you with this, these are just a few thoughts to get you started. ------------------

normally a water pump will not just quit working, unless it is froze up or the belt is off of it. usually it will just leak or start making a noise. you should be able to see the water flowing in the rad. looking through the rad. cap. HINT: take the cap off before you warm up the car.  ------------------
