Q:How long should a water pump last?
You didn't indicate from where the steam is originating. It could be from the radiator, radiator cap, coolant reservoir, cracked manifold, gaskets, hoses, etc, etc, etc, in which case, the water pump may have nothing to do with the problem (of course, a fault pump may CAUSE the problem, but, without more information, it's impossible to give you a specific answer). As far as how long water pumps last, it depends on the manufacture, whether it's new, used, or remanufactured, how much and how hard the vehicle is driven, etc etc etc. Generally speaking, a brand new water pump should last at least 10 years or 100,000 miles. Good luck!
Q:What are the conditions for the series and parallel connection of the pumps?
Water pumps in series require equal flow, and the latter should be able to withstand the pressure of two pumps and.The parallel pump requires the pump with equal lift head, and the outlet pipe in parallel shall be chosen according to the flow rate of two pumps.
Q:97 silverado 5.7L water pump replacement?
sounds like you know what your doing. but i would advise you to take the shroud off first because it will get in the way. you might want to replace your hoses and thermostat also and use a gasket scraper instead of brake clean. happy wrenching.
Q:What's the submersible pump?
Zhengzhou sea diving pump. Deep well submersible pump is a fountain, drinking water transportation, irrigation, hot springs, high-rise transport facilities, etc., deep well submersible pump excellent performance, so widely used in various fields.
Q:How can I find out how to install an auxiliary water pump on a 2003 Jetta 1.8 Turbo?
If its a 2003, you should still have a warranty on the powertrain unless its over 50,000 miles, or so. If indeed the water pump is leaking, you'd be foolish to leave it go; the timing belt can get wet, the belt and jump time and cause engine damage, that would be very expensive!! Save your self a lot of grief later by going ahead and replacing the water pump now; if you feel you're not up to the job, then have someone who knows VW's do it for you. Also replace the timing belt at the same time. An attempts to try and do a temporary measure will be met with an expensive result; a leaking water pump can also suck air into the cooling system and cause a hot spot, which could blow the headgasket, especially on a turbo model VW. Sorry, to tell you this, but its better to fix it now and save money, time, and pain later. I spent 25 years on/off in VW dealership service departments from 1980 till Dec of 2005. A car nut.
Q:Choosing a manual water pump?
There are very small rotary water pumps designed to be driven with hand-held electric drills. These pumps may be purchased in some hardware stores or farm supply stores. One could be adapted to a bicycle- type drive. Small pumps have about a 50% efficiency so you would need to produce sustained muscle power applied at around 150-200 watts to achieve 75 -100 watts of effective hydraulics. Applied watts = (GPM) (PSI) / 1.277 million (eff.) Where eff. is as a decimal. Edit : A 3/8 drill will pull about 280 watts. I can do 200 watts on an exercise bike, but not for long. I am a 79 heart patient, so you can probably do better..
Q:Location of fresh water pump on early 90's Jayco 2500 bumper pull trailer.?
having had many travel trailers the water pump is usually in a cabinet or under a bed or couch with a lot of plastic water lines near where you screw the water hose into the side of the trailer. and they are usually a preset psi from the factory so that is usually nothing to have to worry about and most have an on off switch located in the traier by the kitchen sink.And if the hot water heater is no good look into a tankless water heater it will save you money in the long run but initially you have to have a vent installed up through the roof away from a roof air vent. Another suggestion everytime you move a travel trailer they get the crap pounded out of them and someone needs to go up on the roof with a ladder and/or a plank that goes across the width so there is no weight standing on a roof to make dents or pop seams. Use some plastic stuff like plasticote available at wal mart after you move the trailer and set it up go up and make sure to double coat any of the seams that need it. I crank the heat up inside the trailer and do a double coat the heat rising will put a skin on the plasticote in a few hours instead of 12 or more. and the double coat gets any cracks missed the first time around. After that check it once a year if the trailer stays there.
Q:im making a pond filter. need help with water pump?
1. I had an electrician put a buried cable in the ground coming up to a weatherproof post with outlets and an on-off switch. It was not as expensive as I thought it would be. 2. You can put the water pump and filters by the house or even inside and run buried water pipes out to the pond, or just put the pump inside and have the filter by the pond which would run by water pressure or gravity. 3. A windmill or solar panel. A siphon uses potential energy stored in the water to work. Once the water has dropped through the siphon, there is no more energy to draw from and the siphon stops. A windmill or solar panel could provide the power to lift the water back up and make the process continuous, or at least while it's windy or sunny. However when pricing these two options even though they would be very cool if you have the large yard to accommodate them, they turn out to cost much more than either 1. or 2. and have much higher maintenance costs associated with them. 4. If it's a very small pond, you can get a solar powered filter/fountain that looks like a floating plastic lily pad. My son had one of these, but it only worked on the sunniest of days, and lasted one summer before wearing out. If you add a large block of filter foam over the intake it may last a little longer. Rinse it out two or three times a week.
Q:where produce good quality water pump?
place a bucket outside when its raining
Q:How can I be sure the water pump is the problem before spending $ on repairs. 97 civic overheating.?
You check the water pump by looking at it! Underneath the input shaft of the water-pump is a small weep-hole that leaks coolant if the bearings and seals are shot. If there's no leak in that location absolutely nothing is wrong with the water-pump regardless what you read above. Change the thermostat with a factory OEM unit. Remove the radiator cap when the motor is cold. If the radiator return valve on the bottom is brown and dirty the entire cooling system should be drained, flushed and cleaned. The heater core and radiator cross fins are probably plugged full because of years of not changing the coolant. Is the electric fan working? When the motor starts to overheat, wrap a gloved hand around the top radiator hose. If it's barely warm the thermostat is sticking closed. If it's hot the radiator and entire cooling system needs to be cleaned with Prestone Super Radiator Cleaner.
