Q:When I turn on my pump for the pool water-fountain it will run for 30 seconds or 4 minutes or anywhere in between then it just shuts off. I push the remote on button on again and it runs for a few seconds. Sometimes it will run for a while longer but mostly short durations. Thanks in advance for your help.
outdated wiring. Hire a certified electrician to re-wire it. Could be the timer too! Quit messing with it or you could have an electrical fire. Feel the walls near and around the set up box.
Q:I'm not talking about for a car. Just the standard water pump for you house. Ours won't click on when it's supposed to. First we had to hit the tank itself, and now we have to tap the box on top (I'm assuming some sort of fuse box as there are wires coming out of it). It's getting ridiculous and I'm just ready to buy a new one, but I'm not sure where all you can buy one.
All you need is a new switch. It' the pressure switch that you are refering to and if you have to hit it then it is shot. About $20 - 30 at the hardware store and easy to replace. Be certain to turn off power 1st.
Q:when replacing the Water pump on an Isuzu rodeo while getting a new gasket does it require gasket sealant for this type of vehicle?
it depends mainly on the gaskets you are using whether or not they are paper type gaskets or rubber type gaskets or cork type some cars have only sealant and no gaskets most rubber gaskets don't need sealant some install it anyway for extra protection but to much sealant it could clog your cooling system if they are paper type gaskets a little sealant is added protection some mechanics put sealant on the gasket simply to hold it in place during the install some gaskets require sealant and a specific one at that there are many different types of sealant keep in mind if your gasket manufacture requires sealants to install its would be listed on the box it arrives in for the pre installation guides make sure you get the one they say also all sealant that dry some are wet sealants and never dry, keep in mine that if the sealant requires dry time after install you follow those guide lines otherwise it will leak keep in mind also that the water pump housing bolts have a specific install and tightening and torque down for that type of gaskets like 15 foot pounds on the bolts for cork type gaskets if you crank the bolts down to tight its going to split the gaskets and your back to square one replacing it again
Q:my pump went out and i can't afford to have it fixed at a shop.
Drain coolant from radiator and cylinder block. Remove drive belts. Remove crank pulley. Remove timing belt covers. Note: It is not necessary to loosen or remove the timing belt during water pump service. CAUTION: When removing water pump assembly, be careful not to get coolant on timing belt. Remove water pump. INSPECTION Check body assembly and vane for rust or corrosion. Check for rough operation due to excessive end play. NOTE: Water pump cannot be disassembled and should be replaced as a unit. INSTALLATION Use a scraper to remove old liquid gasket from water pump. Also remove old liquid gasket from mating surface of cylinder block. Apply a continuous bead of liquid gasket to mating surface of water pump. Use Genuine Liquid Gasket or equivalent. Install water pump. Install remaining parts in reverse order of removal. Install drive belts. Refill engine coolant. After installation, run engine for a few minutes, and check for leaks.
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
in case you'll locate the Chilton guide for that vehicle, it ought to have all the tips you opt for to finish that restore. because of each thing going to digital cataloging, many previous severe college save preparation no longer use the Chilton books they have. they frequently carry an complete library of them. see in case you'll get a loose one from the community severe college.
Q:I have oil all over my water pump. I investigated when I saw a few drops of oil in the garage that showed up every few days. I then saw a drop of clean radiator fluid. Does oil come near or through the water pump? I have a 96 nissan maxima if that helps.
get the cylinders checked for pressure. Check the spark plugs for fouling and oil in the radiator. It sounds like you cracked a block.
Q:Why is water pumping cool water is normal, but when pumping hot water pressure and flow are very small?
There may be: first, the water temperature is too high, the impeller damage! But this may not be very likely! Second, but also the water temperature is too high, but may be too high water temperature will be hot water pipe deflated, resulting in no water. Third, it is possible to buy fake and shoddy products!!! Another important problem is that you didn't tell me what kind of pump it was! What forms of work do you have?
Q:i mean, the water that runs through the ground from rain and ends up in the pit in the basement,is it clean to drink in an emergency? live close to a public road where they salt for snow and ice, so do you suppose that is in the water?
The only thing it would be suitable for is flushing toilets.
Q:how do i remove and replace the water pump on a 2003 ford focus with a 2.0 engine
You most likely wont be able to do this at home in your own garage. The water pump on this vehicle is driven by the timing belt. In order to access the timing belt, you need to first remove the accessory drive belt, some pulleys, and i thing a couple components like the power steering pump, and the AC compressor as well. Once you have all that stuff out of the way, then you can remove the timing belt cover and begin removing the timing belt, with the timing belt removed, you can now access and unbolt the waterpump gear and then the waterpump itself. It goes back together in reverse order, except you will need a speical tool to hold the two cam gears from moving relevant to one another when you realign them with the crankshaft to put a NEW timing belt on, you shoudl use a new belt since you are forced to replace it while removing the waterpump. Your going to have to take it into a shop, it will be kinda expensive, a timing belt replacement in that vehicle is estimated at 2.2 man hours, the water pump will be only a bit more labor ontop.
Q:What does the temperature range of the pump mean?
The range of temperature is less than 135 degrees Celsius, which means that the range of use shall not exceed 135 degrees celsius. Refers to the temperature of hot water, high pressure steam boiler inside the water temperature is more than 100 degrees Celsius, your pump is a high-pressure high temperature water pump, generally used for steam boiler or high temperature waterway system.
