Q:My toyota 99 camry stalled and would not start. engine turned over and all lights worked. had the oil changed 3 weeks ago and they told me their was a noise and it might be the water pump. my questions are does this sound like the water pump? Do they usually change the timing belt and is this necessary? is this something that we can do at home? thank-you for any info out their!: Is the car cranking over just not starting? It doesn't sound like the water pump unless the water was ran hot, that would make it not start back up.

Q:I must change the timing belt of my car. I have been told that the water pump must be done too since it is right there. Due to the high price I want to postpone/skip the water pump until the next tune up. What happens if the water pump fails down the road? How long does a water pump last? 120K? My car has 60,000 miles on it. Thank you.: I always suggest at same time. Most timing belt jobs are 4-5 hour jobs and all of that has to be removed to replace the water pumpp, which could be in a week a month or a year (roll the dice) it doesn't usually take much if any additional labor to replace the pump when everything else is out of the way usually just the cost of the pump itself. if you wait and say a month later the water pump goes out you would have the expense of the pump AND ALL THE LABOR AGAIN.

Q:What's the meaning of a single-stage pump?: Single stage impeller or multistage impellerGenerally speaking, multistage impeller is adopted in booster pumps

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: Looks like you're covered with the mechanical aspect of your question! My input involves your comment on its a german car. I have several friends that are mechanics/techs. To a man, they say it doesnt matter what make (Japanese, American,European,Korean,etc.) the manufacturer assembles each for its ease of assembly at the factory. Ease of repair is a secondary consideration. All you have to do is look at their skinned knuckles as proof ! They all well deserve their paychecks!

Q:Had a water pump start leaking, when I replaced it with a new one, it leaked even worse (around the gasket and O rings this time). The process I took...I unbolted everything and removed the water pumpI scrapped everything off with a wire brushI coated both sides of the gasket with red gasket siliconI mounted the new one and bolted it down tightening in a cross pattern(kinda difficult to get everything lined up)It leaked real bad the first time so I loosened the bolts and played with the top rubber seal to make it seat better.It leaked a little less the second time... but still WAY too much.I completely removed it the third time and (totally distroying the gasket) gooped it up with gasket sealer again, along with the O rings and tried again... leaked worse.Considering options... go with a white or black high heat siliconPossibly just using the sealer with NO gasketGooping the HECK out of it with JB-weld and pray!Suggestions?Know what I did wrong here?: The first thing I was taught on Volvo water pumps was to use NO sealer. Get yourself a new gasket.Make sure the block is clean. Install the gasket on the two studs. Grease the heater pipe o-ring after installing on the pipe. Grease the hole it fits into. Install the top seal on the water pump and coat the surface with grease. Install the pump on the block and make sure the pipe has entered the pump. Tighten the two nuts until the pump is almost contacting the block but still moves easily. Insert a smaller Phillips head screwdriver into the bottom bolt hole of the pump and into the block. Lift the pump ,using the screwdriver ,until you can start the top bolt.Then use the screwdriver to wiggle the pump to start the left side bolt. Once you have started those two bolts,the bottom one will go right in. Tighten it all up and install the heater pipe bolt and you are done.

Q:Fire pump room is required to set up water pump control room?: What is the concept of fire pump control room? If there is a control room host automatic alarm automatic fire alarm system of words (through the pump distribution box can also control) can control the fire pump, if there is no distribution box automatic alarm system you can through the pump room control

Q:for a school project, i need to boil cold water using a vacuum pump. I did some research, but i still didn't find what i needed. I need to know what kind of pump i need for this, and where i can get one for cheap, since i will only use it for this project. if you know how to actually use it, you can throw that in as well. thanks!: You can get a cheap hand powered pump at the auto store. They use them to vacuum airconditioner systems and check for leaks in vacuum operated controls.

Q:What are the categories of pumps?: Did you say the pump voltage is 220 or 380?

Q:Which professional friends ask, I encountered a problem in the design of fire pump head 90 meters, flow rate is 20/S, power is 37KW, but the construction side to buy the pump head and flow are achieved, but the power is only 30KW, this relationship? If you can, let me know by the way, thank you: The flow is 20 L/S! Q = 20, L/S = 0.02 m^3/SThe total efficiency of the pump and the motor is estimated to be 60%P=pgHQ/n=1000*9.8*90*0.02/60%=29400W= 29.4, KWLook at the water pump motor power 30KW just enough from the calculation, but there is no room for the use of the attention do not overload!(Note: motor power matching pump nameplate are generally too large, room.)

Q:All the water to my house comes from the river close by - via a 1500kw surface pump, into a large pressurised tank. If there is ever any kind of blockage in the pipe - or if it freezes ...this causes the pump to run - 'dry' - which eventually burns out the motor. I have lost 2 pumps so far because of running dry - and they are very expensive.I would like to fit some kind of automatic cut-out - that will ALWAYS stop the pump running after 15 minutes or perhaps less - as that is ALL the time it needs - if the water is flowing freely - to fill the pressurised tank. I feel sure such a thing must exist - but I do not know what it is called or where to buy one. Does anyone know of a 'switch' of this kind? And where to look for one? What could I put into google to do a search - for suppliers and prices, please?: Put an inline presure switch between the tank and pump so the pump will turn off when the presure in the line drops below a preset presure.
