Typically the water pump will make noise or show residue from leaks from the water pump bracket. You could also use a special tool that puts about 10-14psi of pressure on the cooling system and raise the car and see if it leaks from the water pump.
The fire pump churn test, is when an operator runs the fire pump without the flow of water
import java.util.Vector; suppose-:::: test t=new test(); /**this is how we add elements to vector*/ Vector v=new Vector(); v.addElements(t);
Put it into a bucketful of water, it should pump. Activate the trigger by hand if necessary.
no
you would need a tool which is called a pressure tester, if you see a leak from the water pump during the test then your water pump is bad and need to be replaced a.s.a.p
You might as well change the Thermostat because it is comparatively inexpensive, but test the water pump to see if it needs to be replaced.

Depends what kind of pump. -If a submersible pump, the AMP test is good. If amps are within 'service factor' and pressure is still low, you have a bad 'wet end' or a leak somewhere. - If a jet pump, it may be cavitating, have a blocked nozzle, or have a warped impeller.
Use a digital multimeter and test it for resistance.
magnetising current test, magnetising balance test, s.c test, vector group test, winding resistance test, ratio test
there should be a pressure gauge on a pipe leaveing the pump, or if it dumps into a catch pan then watch the flow,
