loose water pump pulley and overheating engine
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.
no if the pump is leaking it is bad and nedds replacing
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.
Could be, worn bearing/seal in water pump, loose hose clamp, faulty hose, faulty radiator, faulty gaskets, faulty heater core, faulty freeze plugs in engine block, faulty radiator cap, cracked cylinder head,
could have faulty or dirty contacts, pump motor could be bad or the pressure gauge is faulty
A faulty rad fan could have the same effect if pump isn't leaking or making some sick noise its fine thermostat is cheap and easy to replace so go ahead and do it just to eliminate it as the problem good luck.
