1. Most, if not all, water pumps have a 'weep' hole that allows water to leak out when the shaft bearing becomes worn. This hole is generally located at the top of the water pump where the shaft passes out to the fan. If water is leaking out then replace the water pump. 2. A definite loud squealing coming directly from the water pump shaft area is an 'indicator' that the pump is going bad. The squealing is caused by the rotating shaft creating friction against the shaft bearing - something that should not be occuring. If you are just using water in your system then you may be able to prolong the life of the pump by adding the correct amount of anti-freeze. 3. The water pump has vanes (fins) that move the water in the desired direction. I have seen them corroded away - not a common occurance. You can remove the radiator cap on a COLD engine and then start the engine (make sure the removed cap will not become a missle by dropping to the fan). When the engine warms to operating temperature the water thermostat will open permitting the moderate flow of water from the engine and through the radiator. Usually you can see this flow past the radiator cap hole. If the hole is to the side of the radiator you may not see the flow but will be able to feel the warmer, and soon to be hot, water by briefly touching the outside of the radiator tank. (Keep hands and other objects away from the fan!!!) If the flow is not visibly pronounced it may be a sign of worn/corroded vanes. The only real way of telling for sure is to remove the water pump and look. Again, this is not a common occurance. 4. An over-heating engine may be caused by a stuck water thermostat or even an old (usually lower) radiator hose that is collapsing. Some of these hoses come with a spiral of metal, that looks like a spring, that runs along the inside to prvent the collapse.
No water pump is easy to change. You know it is bad if it is leaking, noisy, or if there is no flow of water when looking into the radiator with the engine running. Replace the thermostat at the same time as the pump if it is bad.
If you are talking about the water pump in your car, the likely sign is that that engine overheats and the radiator boils. Radiator fluid will likely run out on the road under the pump and adding more anti-freeze does not help. You may hear a grating noise from the pump if you know where it is. If your engine is cooling properly, you can be sure that your water pump is working.
start engine and getr it to running temp. remove radiator cap. look in radiator. if coolant is circulating, the water pump is working. if no movement,pump or thermostat is bad
It is important to know the signs of a broken part in a car. Signs on a broken water pump would be water leaking from the car, a loose pulley belt and the thermostat warning light comes on.
Fill the radiator up with water then drive the car for a few hours and check it and if the water is down then u have a leak that is one way to tell but that also tell u u have a leak period if not just look at it if it look like water is comeing from the sides of the pump it's leaking you need to fix it or u will run the van hot and blow a head gasket
Can only tell you the cost of replacing the timing belt, water pump, and few other minor items on my 2006 Odyssey Touring -- $750.00 ! Get the parts at autozone or a similar store and do it yourself, not too difficult if you are mechanically inclined, or have a friend who is. Parts should run you $190, there is a kit that includes the belt, water pump and the pulleys all together.

While it is still liquid you can tell by smell. The water based will have very low odour, oil based has heavy odour. Once applied and dried there is no way to tell difference.
1. Diconnect the negative battery cable 2.Drain the cooling system 3.disconnect the hoses at the pump 4.remove the drive belts 5.remove the power steering pump bracket. 6.remove the shroud and fan 7.unbolt and remove the pump. TO INSTALL 9.clean the mating surfaces thoroughly 10.using a new gasket, install the pump and tighten bolts to 13 ft. lbs. 11.reinstall all componets in reverse order. 12.after complete operate the engine with heater control valve in heat position until the thermostat opens to purge any air in system check coolant level and fill as required.
No circulation.
how do you tell if your fuel pump is working
when you engage the ignition.. you should hear it prime.. sounds like a whine..
easiest way to tell if water pump is working is to run engine until at running temp. then carefully remove radiator cap. with someone slightly reving engine, look into radiator. if the pump and thermostat are working correctly, you will see the coolant moving(circulating) in the radiator
Use a digital multimeter and test it for resistance.
If you have oil pressure it is working.
Water pump shaft loose? Water pump leaking? Water circulating in coolant system?
My guess is low or no oil pressure.
Wait until the thermostat opens , so the top radiator hose is hot , then squeeze the radiator hose and then stop squeezing - if the water pump is working you will feel a surge of coolant through the hose if the impeller inside the water pump is fine ( I'm assuming that there is no squealing sound or coolant leaking from the weep hole of the water pump )
I'm not a mechanic / technician but the way that I tell the water pump is working is : I wait until the engine thermostat is open ( the top radiator hose is hot ) and without catching anything in a moving belt I gently squeeze the top radiator hose and then release it slightly , you should feel a engine coolant surge
A fuel pressure test can determine if the pump is working properly or not.
If you hear the fuel pump run that is a good sign it is working however, a fuel pump pressure test would tell you if the pump is meeting the required pressure.
