Q:how do I replace water pump so that water will be dispensed from refrigerator?
There is no pump in the fridge. Water is propelled by pressure before it gets to the fridge.
Q:Is my cars water pump broken? Squealing noise..?

Q:water pump in a 96 neon?
While it is all apart the timing belt and tensioner should be replaced. It will cost several hundred to have it done. Neons don't get much older the 96, I would pay more like $500 for it. Make sure the head gasket is not leaking.
Q:2001 mercury cougar water pump belt broke?
It seems to be a water pump failure, unfortunately that kind of failure is unpredictable and can easily sneak up on you. What happens is the pump fails and then the belt gets literally gets burnt off, this issue can be a cascade failure because the excessive engine heat can cause a number of COSTLY internal engine problems because aluminum engine blocks these days can't handle prolonged excessive heat. Hopefully not in your case, but just to give you an idea of the issue and everything surrounding it. The cost to repair at a shop can run anywhere from 200$ to 600$ depending on where you take it, you can do it yourself if you are mechanically inclined but i suggest a professional because they can also further detect any damage that the pump failure may have caused.
Q:how to tell if water pump bearing is bad?
No it isn't hard to fix, first loosen the little bolts on the water pump pulley, then take the belt off, then unbolt the water pump and take pulley off old pump, clean off old seal from block, put on new seal, you may have to use gasket maker or silicone, install new pump, and bolt pulley on to new pump, then reinstall belt. Oh I forgot you will have to drain the antifreeze before you start, and refill it after you are done! Start the car and let it warm up and look for leaks, if you see a leak you didn't get it sealed properly and will have to repeat the sealing process and antifreeze. Takes an hour or so to do!
Q:What is the function of boiler feed pump, condensate pump, vacuum pump and low drain pump in operation?
The feed pump is a pump for supplying water to the boiler and maintaining the water level of the boiler. The condensate pump provides water to the deaerator after condensing the turbine and provides water for some condensate users. Vacuum pump is to maintain the vacuum of the pump, the pump is to lower the drain in a timely manner to the next level of low pump
Q:where does a car water pump leaks at?
I concur with the weep hole definition. However, when coolant starts to leak through that hole, it is time for a new water pump. Which engine do you have? If you have the 3800 V6, that pump is fairly easy to change. The 3100 and 3400's water pumps are also fairly easy to do with some twisting and turning of the hands. Either way, make sure you get the right water pump for your engine.
Q:01 Tacoma 3.4 V6, does anyone know the average life of the water pump?
Water pump life is a direct function of proper maintenance, therefore there is no real answer to your question. At 89k you could certainly elect to replace the WP as long as the T-Belt is also being done, but it is purely a preventive maintenance item. Might save you a lot of money later, or it might not. Impossible to say. It will give you more peace of mind though.
Q:What is called soft start of water pump?
Soft start has many methods, mainly used in high-power motor.Through soft starter, or frequency conversion start, or star triangle start to achieve.It means that it starts at a slower pace.
Q:doubt about water pump..?
Is the motor of the pump built-in so that the pumped fluid flows through the motor also? If the answer to the question is yes then do not use the pump for pumping kerosene. However, if the pumped liquid does not come in contact with motor then you can use the pump for pumping kerosene. But ensure that the pump shaft seal is of mechanical type (so that kerosene does not leak from the shaft sealing area) with parts (specially any rubber parts) compatible with hydrocarbons (use viton rubber parts instead of EPDM)
