When a water pump is bad it will leak. There is a hole in the pump were water will leak out of.
Faulty pump, return it for another.
Yes it could.
No, but faulty water pump or thermostat can.
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.
overheating/underheating water leaking from bottom of car behind fan. squealing
You will know if you have a leaky water pump because it will be leaking coolant out of the water pump.
This can be caused by a number of things. # A shortage of coolant # faulty thermostat # faulty radiator cap # a blocked radiator # faulty water pump # faulty fan # leaky hoses # cracked head or block.
no if the pump is leaking it is bad and nedds replacing
If it leaks or it doesn't pump water.
could have faulty or dirty contacts, pump motor could be bad or the pressure gauge is faulty
Probably not. It sounds more like a faulty water pump, water tank, or well. Most likely the water pump is directly at fault, but faulty tank pressure, bad electrical supply, or a bad well can cause the pump to do that. Especially if the surges are repetitive in nature, your pump is short-cycling. With lots of research, you might be able to narrow down the problem.
