Hello has any body have a way to check a water pump to see if its working ?


I'm not a mechanic / technician but what I do is with the engine warmed up , so

I know the engine cooling thermostat is open ( the top radiator hose is warm )

and without catching any clothing etcetera in the moving parts , I gently squeeze

the top radiator hose and than let it go slightly , if the water pump is working

I can feel a surge of engine coolant going through the hose
