Q: Can I put in fluid and drive to the Service Station or should I have it towed? The fluid flows out as fast as I put it in. Thanks!: Unless the shop is very close 1/2 mile or less, have the car towed. Overheating a car can cause major internal damage, that will cost a lot more than the tow bill to repair!

Q: Assuming that my water pump standard flow is 20m3/h, tolerance value requirements is + 8%, then is not traffic 22m3/h is not qualified?: Tolerance coefficient is due in the manufacturing process, will, so each pump products are possible shapes and sizes do not conform to the pattern of the situation, and ensure the test results in the value (operating point) when compared, should be allowed to have a certain tolerance. It should be noted that these tolerances are only relevant to the actual pump and do not involve test conditions and measurement uncertainties. If the pump at a certain working point (the same lift) standard (Design) flow of 20m3/h, the actual flow of 22m3/h, indicating that the pump in the design process has unreasonable place, resulting in waste of power. Deviations from the manufacturing process usually have no positive deviation.A pump is a machine that transports liquids or pumps liquids. It will be the prime mover of the mechanical energy or other external energy transfer to the liquid, the liquid energy increase, mainly used to transport liquids including water, oil, alkali liquid, emulsion, suspension emulsion and liquid metal, but also transport liquid, gas mixtures and liquids containing suspended solids. Pump performance of technical parameters are flow, suction, lift, shaft power, water power, efficiency, etc.; according to the different principles of work can be divided into volume pumps, vane pumps and other types. Displacement pump is to use its studio volume changes to transfer energy; vane pump is to use the rotating blade and water interaction to transfer energy, there are centrifugal pumps, axial flow pumps and mixed flow pumps and other types.

Q: i have a jetta and would like to know how difficult it would be to do. I know its a german car this is why i ask. thanks: The water pump is driven by the timing belt on that engine. You don't have to take the alternator, power steering pump, or the a/c compressor off, but you do have to make sure it is timed right. Not too hard to do, just make sure the marks line up. Good luck!

Q: Is it normal for my sump pump hole to be empty. No water in there.. ??: If you have had a dry spell or live on the top of a hill, the water table will be lower. A dry sump is normal. If on the other hand there is wet ground around the outside of your basement walls, then you have a drainage problem. The water is not reaching your weeping tiles. Get someone to dig down to the tiles and cover them with your municipality's recommended level of gravel/sand

Q: Hi I really need a USB water pump (small). I have found one in China but they need payment in a different currency so its proving difficult. I would much prefer a US/EUROPE seller. Cheers.PSgt; If I had to pay to get the power supply changed from wire to USB then I could if anyone knows who could do this.: The USB output has a 5V power supply. USB2 delivers up to 500mA and later versions may be 900mA. USB hubs start off with less than this (100mA) but change as they are initialised. Some dedicated USB charging ports supply up to 1.8A. There are some USB power cables that take the output from 2 ports in a sort of Y harness (first link for example). The result of all this is that only a very small pump would run from most USB ports. I did find 2 rated at 5W and 8W but the voltage was not shown. I suspect they were mains operation, meant for large water bottles. If they were 5V they would use 1A and 1.6A respectively, so only run from special USB charge points or double cables, and only in some cases anyway. I assume you want to run from a Laptop/Notebook battery for convenience. The point is that even if the USB port can supply the correct voltage and current the battery would be emptied very quickly. It is probably cheaper to get a suitable pump, then power it from a separate and more suitable rechargeable battery or mains adaptor (wall wart), whatever it takes, taking into account how long it should run with a single charge. This is about the battery voltage and the capacity in ampere hours - the number of hours it can supply a given current. D size rechargeable (Ni-MH) would run a 6V x 6W motor using 1A for about 6 hours. C size cells are half that, and AA cells about half again. It takes 4 cells to get 5V. Get them as a pack though or at least with a battery holder, as they cannot be soldered. Then you need a proper charger. Recent laptop/notebook batteries are lithium ion types, 10.8V and 4.8Ah, so deliver 1A @10.8V for 4h more or less. Other types worth considering are for cordless drills.

Q: The water pump in my 2001 PT Cruiser needs to be replaced and I'm wondering how much I'm looking at. I know it would vary and I know it's supposed to be labor-intensive but I thought I'd ask on here before I call my mechanic. We are trying to figure out if we should just go ahead and look at getting a new car. Thanks for any help!: It received't run without the belt, so except it truly is on the broking already, difficult to commerce a lifeless motor vehicle. Get a quote on the upkeep, see what it truly is. It received't damage absolutely everyone to ask about what they could furnish you with as a commerce, both.

Q: I just put a new water pump in my jeep and after I put it in I ran it and it seemed to have a small leak while it was running it seems like it was coming from the crank which is under the water pump so it might be a leak coming from the bottom of the pump. When I turn the car off it is no longer a leak its more like pouring water out. What do you think it can be? I put a gasket and the blue silicone gasket sealant all around it and on it before I put it in so I have no idea. Thank you for the help.: The blue silicone has caused a hole in the water pump. Get it fixed now or the blue silicone will leak onto your engine causing more damage.

Q: 55KW how large is the water pump wiring?: Transmission within 100 meters, 70 square millimeter aluminum cable, or 50 square millimeter copper cable. If you exceed 100 meters, you'll have to add a number to the cable.

Q: The garage told me my water pump was pumping quot;weaklyand needs to be replaced.: Good question (finally). It will pump weakly if it is not turning fast enough or is leaking at a seal. If you have a faulty belt that is slipping it will not turn fast enough. Go to another mechanic.

Q: I have a 2000 A4 1.8 T with 91 k miles on it. I went to the dealer for my oil service. I told them that I hear a quot;clinkingnoise when I start the car and that it goes away after the car runs for 5 minutes. I told them to check this also. They diagnosed and said that the water pump has gone bad and needs to be replaced. Since it was close to 105 K miles, I might as well change the timing belt. Total charges for both is 1250. And they also see that Cam Seals starting to leak oil. Since I was doing the timing belt, I might as well change them too. Additional cost to do them is 950. So the total for all three comes down to 2200. I bought the car at 90 K and checked it at Firestone and they said it was cool. They noticed an oil leak but said it was not anything major that needs to be taken care of right away. Do you think the dealer is taking me for a ride here? I just drove 500 miles and would things go this bad all of a sudden? Or should I make the replacements? Please advise.: I used to work for a dealer, they price by the book, even if they are already in there.... so if say you want to replace your alternator and your belts, they look up what labor is on the alternator, and then look up what labor on the belts is and add them together, even though youd have to pull the belts to change the alternator anyways. So basically you get charged for labor twice under this system. A different shop should be able to do this cheaper. If your water pump is out you should be overheating...... If youre doing the timing belt though, you probably want to look into those cam seals, if they leak on your timing belt they will weaken the belt and maybe make it break, which is really bad if you have an interferance engine (meaning if the pistons are up and the valves are down they will hit, usually breaking/bending the valves). The dealer should know if its an interferance engine or not, or you could do a quick internet search. If the belt has never been replaced i would definately recommend doing it though. Whatever you end up doing though, i would get a second opinion from a non dealer. At toyota they would charge more for lexus parts than toyota parts, even though it was the same part with a different part number... you may be in the same sort of boat with the audi.
