Q: My boyfriend told me that my car needs a new water pump. He said this because when you start the car, it sounds like trickling water is coming from somewhere in the engine bay. The car overheated once before and he put coolant in it, ever since then, it hasn't overheated. But last week he told me that I shouldn't drive it at all because the pump is about to go. I went out today and started it to see if I can hear the quot;grindingnoise that I read about online and all I hear was the trickling sound. It's rainy outside so I can't tell if the pump is leaking water from the quot;weepquot;. Is it the water pump? I want to make a two mile round trip to go pick up sushi and the place is a mile there and a mile back. Will I seize my engine or get stranded if I make this tiny trip? Is it my water pump?: You don't mention make, model, or year, but it could be the water pump or some other leak. Your boyfriend can see the car so I am leaning toward his explanation. Check the first source for your make, model, and year, and engine type if you know it. If the entry for your car (or for any of the engines for your car, if you don't know which one) has a # after it the timing belt drives the water pump. If that is so, don't drive it at all until you either determine it is not the water pump or it is repaired. If the pump seizes and it is driven by the timing belt the timing belt will fail. And if the engine is an interference design (has an * along with the #) that will probably cause serious engine damage. The safe thing to do in any case is to try to bum a ride from a friend in the meantime. The shifting problem is probably something else.

Q: does anyone know how a water pump works????????????: Water pumps are available in different types. 1. Centrifugal type: Operate by increasing the velocity of water which, when the velocity is decreased by the Volute casing, the pressure increases. 2. Rotary Gear type.: Operate by Displacement of the water by rotating, gears that trap water between the teeth of 2 rotors of inter-meshing gears that release the water at a higher pressure on the opposite side of the pump to the intake. 3. Piston (reciprocating) type: Also a displacement operation by a piston moving backwards and forwards within a cylinder (like a hypodermic syringe in operation). Back stroke takes water into the cylinder and forward stroke discharges it at a higher pressure. (Double acting types are also used that take in and discharge alternately from both ends). If you mean the water pump of your car, they are generally of the Rotary type.

Q: Pump pumping small is what happened?: You are lifting pump or submersible pump ah? Lift pump before pumping water pump, first open the pump and then open the outlet valve, and if there is no pressure, it is time to leave, the sealing performance is not good, check where leakage, and perhaps your pump is broken

Q: I am trying to increase the pressure of my shower and I am looking to install a water pump. Does anyone know what kind of pump would work well for this? I don't want a big pressure pump, just a small one that will be cheap.: American Standard has a shower head with a turbine in it. Get that. its made for low flow applications.

Q: I was driving when my temp gauge shot up all the way so i pulled off the next exit and my car shut off and started smoking i noticed the water pump belt was in shreds and what seemed to be anti freeze fluid and water was everywhere. I'm curious what could have broke maybe a gasket or the waterpump it's self besides just the belt?: 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: Difference between primary hot water pump and two hot water pump: Primary pump variable flow VPF (variable primary)Flow) system is the new layout of central air-conditioning system, compared with the one or two pump system has more advantages in initial investment and operation cost. At present, some with a pump with variable flow system engineering in the operation of many problems,

Q: We have a 92 cadillac deville, my husband can replace the water pump he justs need to know if you have to jack the motor a little. Please help before our car blows up!!: Make a run to your nearest AutoZone pick up a repair manual. THey're maybe $15-20, but pretty useful.

Q: Hey for the past month my car has been leaking coolant, making a wierd noise when i drive it, and saying low coolant when its filled to the top.my husband took it out to get gas this morning and it stopped on him and had to be towed to the mechanicthe mechanic said its the water pump and somethin about anti freeze and this cost almost 300 bucks with parts and laborim just wanting to know if a water pump does indeed cause issues like this before we dish out this kinda money!!! btw its a 96 chevy luminathanks: The water pump pumps cooled water around the engine, so yes if it has an issue like leaking then there is a very high chance that the engine will overheat. Anti-freeze is only really required in the winter when temperatures get low enough to freeze the water in the system and therefore will not be able to be pumped around the engine, as it's now summer there is no danger not using anti-freeze but is advisable to get some added before the cold weather comes.

Q: I have a toyota supra 83 Mechanic said water pump is leaking into engine causing white smoke. He said that hell have to replace water pump nd all gaskets estimated about 500+$ is this accurate? Also water resevoir mysteriously loses water can it be a symptom?: Sounds fair to me. if it's a 7mgte have him do the timing belt while he has it all apart.

Q: I must change the timing belt of my car. I have been told that the water pump must be done too since it is right there. Due to the high price I want to postpone/skip the water pump until the next tune up. What happens if the water pump fails down the road? How long does a water pump last? 120K? My car has 60,000 miles on it. Thank you.: There is no guarantee on how long the water pump will last, but normally 100,000 miles plus. But that is true of a timing belt too. The water pump has a weep hole at the bottom, visually check for corrosion or rust in that area. If you see some, could be a sign that it is ready to go soon. If not, then do the repairs that you can afford. But why the heck are you changing a timing belt at 60,000 miles.
