Q:Could it make coolant quot;Boilquot;? Ive heard myc ar's behavior is Normal, and most likely just heavy condenstaion as it DOES go away, also the behavior of the coolant and the tank.. but i DO know the Water Pump is quot;Weeping,or quot;Seeping,so i wonder what interaction that would have ont he Cooling side of the motor; what effects can it produce? What would i notice?My 1991 Calais 2.5L quot;Iron Duke,: Steam coming from your headlight on a rainy night is NORMAL, since the halogen bulb makes a lot of heat. This turns the water into water vapor, (steam) as it attempts to dry out. If you don't physically hear the bearings in your water pump, or watch colored fluid drip out from under your engine, then your water pump is JUST FINE!!! STOP WORRYING! I answered one of your questions the other day. If you take my advice, your engine will run at it's best. For extra protection, drain and flush your cooling system out, and use Mercedes coolant. Dex-cool has been proved to be a potentially bad coolant. READ the dexcool litigation websites. Mercedes coolant, which is YELLOW in color, will last for 150,000 miles, and is a time tested WINNER!!! Use ONLY top tier fuels (read about this on web) and use ONLY synthetic oil, like Mobil One. CLEAN your idle air control valve and throttle plate. AND STOP WORRYING!

Q:My car is Grand Marquis. I want to remove the water pump. After removing all the bolts on the water pump, it is still there. I tried to hammer it in order to loose it, but it is still there. I use long tool to lever it off, but it is still there. I even break the corners of the water pump, but it is still there. PB Blaster is used, but useless. I am helpless. Can you help me?: It would help to post the year, engine size.

Q:How do the water pump work please till me water pump mechanism?: Water pumps can be positive displacement or impeller type. Either of these increases the pressure of the water and so can move or lift the water. Centrifugal is an impeller type where a sort of fan blows the water. If the fan stops the water can flow back. You'll need to prime these if they get dry. Fishtanks might use this. Positive displacement means that the water is pushed by some sort of piston. Diaphragm pumps are positive displacement and useful if you don't want the water to run back. Also you won't need to prime it because won't drop the water out when it stops. I'm not sure where hydraulic ram type pumps come into this scheme but they rely on the inertia of moving water to generate high pressure pulses to pump water.

Q:I am trying to evaluate my well water pump and water system to see if the pump is cycling on/off too frequently. What is the optimal quot;ontime? What is the optimal quot;offtime? I have heard the term quot;short cyclingquot;, but no times were attached. I have heard that too frequent cycling can cause a problem, but, again, no times were attached. How can one tell when the system is working within the optimal/normal range, so that no harm is being caused to the system? Thanks.: There is no optimum time. This is dependent on several factors. Assuming you are pumping into a small tank which is pressurized by the inflow of water from the pump (and the pressure also controls the pump) these reasons can be excessive use of water, the air space at the top of your tank has been absorbed into the water over a period of time and the volume of compressed air too small causing the pressure to drop too fast, or you could have leak in your water piping. If there is not enough air space in your tank, the pump will cycle extremely fast. If you don't have a tank, then the above information is incorrect. Good luck.

Q:yesterday the electric went out for a while we had some big storms and now the water doesnt work, the pump is running but there is no water coming out, i need help on how to fix it, please. hurry: You might need a new foot valve. That keeps the water from draining back into the well. Depending on what type of pump you have, could be at the bottom of the well. To bleed the well, you need to remove the plug on the motor...it looks like a nut...about 3/4. You remove that and fill with water...when its full, turn the pump on and keep filling it till it gushes out...put the plug in (with new teflon tape) and it should work. Be careful not to touch the electrical, could get shocked. Its easy if the foot valve is good.

Q:ok so i have a crack in my radiator a small crack but anyways yesterday it caused my car to over heat. i normally keep coolant in the car but it just got low and over heated pretty bad. so today the car is making a really loud annoying noise. coolant is also draining out of the bottom of the engine when the car is on. at a pretty good pace. it is coming out like right under the belt area so my friend said it is probably the water pump baring and he said it could have gotten damaged when it over heated. so i think these symptoms def point to the water pump. anyways i called a mechanic and he said that he had to change the belt to and he said he had to charge me $385. what you guys think. does he need to change the pump and the belt or just the pump? and is $385 a rip off or is that the going rate? thank you all for your knowledgeand information: Read the above PLUS realize that you MUST use ONLY genuine Toyote coolant in your car. Other coolants will cause further deterioration of your cooling components. I have seen Toyota cylinder heads that look like Swiss cheese from using the green stuff. Also, make sure that your mechanic uses only genuine Toyota replacement parts, and NOT rebuilt pump. Replace the tensioner and idler pulleys now, as well. The price is a rip off if cheaper parts are being used. If these are all factory parts, then this price is GREAT!!

Q:my water pump is leaking how do i change it out: The internet in great - - - you wonder how they (whoever) can load so much info ! SO just Google :change water pump - 1989 cadillac deville and you'll get many sites with step-by-step instructions.

Q:We came home one day to find our bathroom floor soaked, and we had no water at all.we later found out that it was the washing machine hose leaking.Our friend primed the pump but isent an expert..we fixed that problem with a new hose.A few weeks after, we started to notice that when you are in the shower, the water would shut off for a minute and come back on for a minute, so on so on, perfectly timed., and this got worse and worse, yesterday it would be on for like 20 secconds and off for 3 minutes... last night the water was working good but today we woke up with no water.The water taps in the house hardly do it at all. I also noticed that when we are running water the water pump goes crazy fast, i can hear it because its a mobile home.: if you are sure that your well is good then .......... sounds like it is time for a new pump - money saved $150, plumber house call pretty easy fix get your pipe wrenches after you turn of all the water mains and remove the pump - even go borrow some or buy some still cheaper haul it to menards or lowes puchace and identical one in a box - name may be different read the instructions - this is the important part reinstall the pump tada all done - good days work for a novice - accomplished something and earned that hot shower and saves about $300 or more by not calling the plumber - plus that 150 for a total of about 450 - cha ching - new blue jean for the kids, a car payment whatever suits

Q:25KW what is the lift of the pump?: 2 floor, the following formula is not accurate, the margin of safety is too large.N=Q (L/s), *H (m), /102/ (0.6~0.85), /0.85As follows: for reference only: (pump flow * pump lift) / (367* pump efficiency) * pump motor power safety margin (constant general take 1.1-1.2) = pump power.Unit: flow M3/H, head MNow you know the power of the pump, but you do not know the efficiency of the pump and flow, so the pump head can not be calculated.Can the normal operation of pump flow velocity detection using ultrasonic detection equipment, combined with the calculation of pump diameter of the flow and shaft power testing equipment can use foreign advanced measure pump, electric motor with related input parameters to calculate the pump efficiency. Then use the formula above to calculate the pump head.The simple way is to ask the designer directly about the design parameters.

Q:Ok, I took my '93 Jeep Cherokee Sport 4.0L in to get the serpentine belt replaced, as the old one had snapped. They told me that the water pump had locked up and that's what made the belt break. The thing is, I had to get the radiator and water pump replaced this past summer and I am wondering what might've made my water pump lock up since it is new. The Jeep has a lot of miles and I'm slowly having to fix a lot of things, so I'm trying to be sure that I don't fix the pump just to find another problem. Also, the repair place told me the water pump looks brand new, so I know that it was definitely replaced, but should I contact the place the fixed the pump and radiator and see if there's some sort of warranty on the pump?: If the pump is 6 months old it should be under warranty. The labor to replace it will probably cost you though. If you are having the work done at the same place that did the previous work, they may do that part of the labor free, just ask. Additional: More likely the pump failed first and broke the belt. If your engine has an automatic belt tensioner, you cannot over tighten the belt. Have the tensioner checked and replaced if needed as well. The labor should be minimal as they already have the belt off to do the additional work. It could be the alternator is used as the tensioner in which case, there is no automatic tensioner. Have any idler pulleys checked out while the work is being done. Ask your mechanic.
