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.
if you are talking about the weep hole in the water pump. that hole will let water out when the seals in the water go bad. that will tell you to get the water pump replaced.
thay usually leak at the bottom of pump out the releif hole. or if it is noisier than usual it can go bad.
The use of regular water creates sediments and bad function of the water pump bearing.
yes and no, if the water pump seals are bad antifreeze will leak from the weep hole on the water pump, but it is possible for the pump to go bad and not leak at all.
it get rusted
Sometimes they'll emit a high pitched noise before they go bad. Is your engine running hot? Could be a bad thermostat.
Most water pumps have a (weep) hole just under where the pulley go's into the pump body.=ok you fan blade is bolted to the front of your pump. looking down if you see a trinkel of water or a water stain on the front of it under the shaft you can bet your pump is gone.=
Yes. A pump does not have to leak to break down
The alternator is belt driven and so is the water pump but that is where the correlation ends. There is no way a bad alternator could cause a water pump to go bad unless the alternator pulley was warped. Then there is a small chance.
the timing belt can cause a water pump to go bad if the belt is on too tight, because that will put stress on the bearings making it wear out rather quickly.
Only if it's going bad. When the bearing and seal are starting to go bad the water pump will leak from the weep hole.
Normal wear on the bearings inside.
