Q:It has a small leak that started this day and it has 60000 miles on it , also new or rebuilt . What is the appr. cost tohave a shop do it ?: its not that hard, but you will need special tool to hold pulley and wrench to loosen fan clutch, just so you will know.

Q:We had to have our well pump replaced yesterday, how long before the well settles down, and the water tastes like it used to?The company who replaced the pump told us when changing a pump it disturbs the well, and it would take time for everything to settle back into place. Thank you in advance for any and all suggestions.: turn on faucets and let the water run until your happy w/ the clarity of the water,,,,this may take hours

Q:it's not doing anything. about a month ago, i changed the pressure switch because it the water just suddenly stopped (like now), and after changing it, it worked again. I did noticed that after changing the pressure switch, it was tripping a lot (the pressure switch). when the water pump stopped again (this time), i went a bought another pressure switch thinking that it was the same problem, but this time it didn't solve the problem. Came to find out later, that the pressure switch that i had changed about a month ago, it was wired incorrectly - maybe that's why it was tripping a lot? so i did wired this one correctly, but still didn't work. Did i burned the pump? another note here is that it has been less than a year that i changed the water pump. My question is, what could the problem be this time? did i burned the pump because i wired the pressure switch incorrectly? any suggestion, please email me thanks!: Easiest way to tell is to bypass the pressure switch and connect the pump motor wire directly to incoming power and manually run the pump until you reach shut off pressure... use your circuit breaker to do this.. My guess is that when you wired it the wrong the first time you forced the pump to shut off by way of an overload protector on the motor and either the protector is bad now or the motor is

Q:What is the function of open circulating water pump and shutdown in thermal power plant?: Open pump and closed pump, circulating water pump seems to be the full name of the pump, the industrial pump is to provide industrial water. Both open and closed pumps provide cooling water on the side of the machine, just because the requirements for water quality are different. Closed water is desalted water, while open water is recycled water.

Q:Im replacing the water pump in my 1992 toyota celica, and i cant get the pully off! i have been working hard for like an hour, i took the belts off. all i have is good old fashoned sockets and crescent wrenches. do i need to get the pully off? and is it lefty loosey and righty tighty or righty loosy lefty tighty?? because sometimes i hear they reverse it. thanks- jordan: I think the water pump for this car is timing belt driven, and the pulley is part of the pump. Don't you have the new pump to look at? If it's not driven by the timing belt, then you remove the 4 bolts counter-clockwise, then the pulley should slide off.

Q:they say a water pump going bad is supposed to weep out of that hole....Yet I see that a new water pump kit has two gaskettes.some o rings....is it likely that it can leak from these sources and still not come out the weep hole?They talk about berring that could go bad or seals gone bad...does this occure in the area that gets inserted into the engine( the turbine portion of the pump)if you had to guess..where is the most likely area for a water pump to fail...if seems like I have wetness off to the left( back toward the firewall) and less off to the right( front of the car)..more off the left..it is very subtile off the right.I don't see anything coming out of the weep hole..BUT the weephole is directly on top( dead center)and back towards the engine in this model. I have the car jacked up on the passengers side/next to the wheel wellso the fluid is most likely to flow backwards toward the drivers side.: Here's the deal. You have to look at your cooling system as a whole system, not just a collection of parts. What makes you suspect the water pump? Is the vehicle overheating? Are you loosing coolant? How many miles are on the vehicle? Everything is a clue to the answer. Where is a pump most likely to fail? Anywhere. A lot of times the impeller will break, but sometimes the gaskets rot out, sometimes the housing itself cracks, sometimes the bearing freezes up. Could be a couple different things. I am assuming by your description you have some type of transverse motor. Could a bad water pump be spraying coolant all over your firewall? Sure, but so could a bad hose or bad clamp somewhere. A hole in the radiator could spray coolant that far back under pressure, although you would probably see moisture around the radiator as well. It's impossible to say without inspecting the vehicle in person. My personal opinion, stay away from the big name parts retailers employees unless you KNOW they know what they are talking about. Some of them do, many don't. They are hired to sell parts, not diagnose problems. Even if they do know about vehicles they can't give an accurate diagnosis without looking first hand. You are better off to find a small local shop with a good reputation and have them look at your vehicle for you.

Q:QDX is a submersible pump. What does "X" mean?: QDX is a submersible pump model, its specific meaning is:1.Q: submersible pump.2.D: single-phase power supply, three-phase electricity is not marked.3.X: pump, pump type is not marked.Complete submersible pump model will generally add rated flow, rated lift and motor power rating. For example: QDX40-8-1.5, meaning with single-phase 1.5KW motor, rated flow of 40 cubic meters / time, the rated lift of 8 meters under the pump submersible pump.According to the different relative position of pump and motor, submersible pump is divided into pump type and pump type. The pump submersible pump motor in the above, below, this structure greatly reduces the radial size of the pump, so much for submersible pump and small submersible pump operation. Submersible pump submersible pump on top of the pump in the following, it is divided into two types of internal and external type. The submersible pump carries the liquid through the annular flow passage around the motor, then cools the motor and then flows out of the pump outlet. Even though the pump is near the drain sump, there is no need to worry about the temperature rise of the motor, so the application is becoming wider and wider. External pump submersible pump directly from the pressurized water chamber after the impeller or diffuser outlet of discharged liquid, motor is cooled by liquid pumping. As the lower pump structure can work in a relatively shallow liquid, it is often used in submersible pumps for operating surfaces, especially the main structure of large caliber submersible pumps.

Q:my sump pump keeps filling with sewer water. i cant figure out why or where it could be coming from. and the smell is awful.: A sump pump is designed for use in the basements of homes whose water tables make them prone to flooding. Many basements are actually below the water table. This means that should the integrity of the walls or floor of the basement be breached, the basement could flood. This would result in thousands of dollars of water damage to anything in the basement, as well as the loss of anything irreplaceable that's stored there. Even should no breach occur, a great deal of moisture and condensation forms over of time within such spaces. Typically the water drains into a hole in the basement floor called a sump pit. When the water level in the hole rises to a certain level, the sump pump engages and removes the water. A pedestal sump pump, for example, has a long rod that extends down into the sump pit. At the top of the rod sits an electrical motor. Beside the rod is an inflated plastic bubble such as the kind one finds in flush toilets, attached to a pressure switch. When the water level rises beyond the bubble, the bubble is buoyed upward and activates the pressure switch. The switch turns on the electric motor, which sucks the water out of the sump pit and passes it through a connecting PVC pipe. This pipe may lead outward into the soil away from the house's foundation, or it may be connected to the wastewater system that connects to the house's drains and toilets. In either case, the water is pumped out automatically.

Q:Was able to remove all bolts except the one in the rear of engine one of the bigger bolts the pulley from the serpentine belt blocks itdoes the pulley need to be removed and if yes then how: Sometimes there are holes in the pulley and you can rotate it until the hole gives you access to the bolt. If there are no such holes, then you will probably have to remove the pulley. The pulley may be fastened with one, four, or zero bolts. If there are bolts for the pulley, remove them and proceed with common sense and use a puller if necessary. If there are zero bolts holding the pulley to the water pump, then it is pressed on and you will need to remove it with a specialty tool called a pulley puller which you can get as a loaner or cheap rental at many auto parts stores. The pulley must also be reinstalled with a pulley installer, also available as a loaner or cheap rental. Are you replacing the water pump or just removing it to do other work? If you look at a new one and it doesn't come with a pulley on it, then you know that the pulley must be removed to go on the new pump no matter what.
