How can you tell if you have a problem with your water pump?

If the engine is overheating and you have checked all other causes of overheating. Start the engine cold and immediately remove the radiator cap. Look to see if you have flow. If not, the pump is more than likely bad. If the pump is leaking, making any noises, or the shaft can be moved from side to side, the pump is bad.
