To the best of my knowledge, if the pulley is turning when the engine is running and there are no leaks from the water pump, it should be fine.
A2: It shouldn't make a squealling sound , either. It can work passably and still have a bad bearing and/or seal. A bad bearing, though it may not leak, is a sign of imminent failure.
The water pump works in conjuntion with the cooling system to cool the engine down on the vehicle. Check the site out below is has the basics for engines (and a few other things as well.)
bad water pump bad water pump check and see if the fan works too.
The water pipe from the pump to the ice maker is quite thin; check it to see that it is not plugged. Check to see that there is water also at the inlet to the water pump. If there is not, check that the pipe leading to the water pump is not plugged.
asapHow do you check for a bad water pump on a Nissan quest
it works like when you drink water from a pipe.
since check valve holds water in the line can a hand pump be installed between the check valve and water tank?
A foot valve, in relation to a water well, is a check valve at he bottom of a well to keep the water from running back into the well from the pump when the pump is not running. If the check valve does not hold the water the pump will lose it's prime and will not pump water.
the watetr pump will be noisy will leak water at water pump weep hole and motor will overheat. there is three ways to check water pump first with engine at normal temperature squeeze radiator top hose if water pump is okay you will feel a pressure surge as hose is released check for liquid leak at water pump and lastly grab water pump pulley and check for play if it is loose it will be noisy when running
Check the water pump drive shaft. If water is leaking from the hole beneath the drive, it's definitely a bad water pump seal and you can't repair them.
check your water pump
A digester feed pump forces water to a boiler. It works by transferring cool water to the boiler to be heated.
did you try replaceing the thermostat or radiator or even check the hoses
