Q: If the water pump does not get water to pump, will it be burnt out? If so, then can it be fixed? And if it doesnt get water to pump, what exactly happens to it?: Running a pump without water to cool it will cause it to overheat. Bearings fail and the insulation on the wiring in the motor burns. The motor can be rebuilt, but it's usually less expensive to replace the whole thing.

Q: My mechanic doesn't get back in town until next week, and I'm struggling without my car. I don't really have any other options mechanic wise and I'm not dropping $1000 like meineke wants.How easy is it to follow the Haynes repair manuals or any other repair manuals? I have a 1996 dodge avenger and I need to replace my water pump. I know it's a time consuming task, but is it especially hard to replace it?: If you don't have any experience working on cars aside from changing oil my suggestion is to take it in and get it done. You need to drain the coolant, loosen the belt, and then try and torque off those bolts that are prolly sticky on the water pump. And if the water has eaten through the gasket you may need to get the engine block redone where the water pump rests. Oh but don't go to Meineke yuck, you might as well pull your pants down at your own house and sit on a plunger handle; at least it is free and will probably be less painful.

Q: Having a hard time taking out the water pump on my 2004 Grand Am. it's been leaking anti-freeze for some time and finally had the time to fix it. Didn't know it will be so difficult to take out. So hopefully it won't be so difficult to put back up.: You did not say if you have a 4 cylinder or a 6 cylinder. The 6 is really easy so I will assume you have a 4.If equipped with an automatic transmission, remove the exhaust manifold. Refer to Exhaust Manifold Removal in Engine Mechanical - 2.2L (L61). Drain the cooling system. Refer to Cooling System Draining and Filling . Raise and suitably support the vehicle. Refer to Lifting and Jacking the Vehicle in General Information. Remove the right front tire and wheel. Refer to Tire and Wheel Removal and Installation in Tires and Wheels. Remove the front fender liner. Refer to Front Fender Liner Replacement in Body Front End. Remove the access plate on the water pump sprocket from the timing cover. Install J 43651 to the water pump sprocket. Use the access plate bolts to secure J 43651 to the engine front cover. Remove the bolts that secure the sprocket to the water pump. Remove the bolt (1) that secures the engine block to the water pump. Remove the bolt (2) that secures the engine front cover to the water pump. Remove the feed pipe that joins the thermostat housing to the water pump. Remove the 2 bolts that secure the water pump to the engine block. Remove the water pump.

Q: How many kinds of pumps are there? What are the advantages of soft start?: The starting modes of water pump are direct start, star triangle start, reactance start, soft start, step-down start and frequency conversion start.1, direct start, generally suitable for small power motors, generally only in the following 15kw pumps, cheap;2, the buck start is the star triangle conversion start, that is, the start is accelerated two times to reach the rated speed, generally in more than 18.5kw pump use, moderate price;3, soft start is gradually increased to the rated speed, the impact on the pump is very small, the price is relatively high, is generally 3 times the buck start;4, the highest frequency conversion is started, in addition to the advantages of soft start, but also can be set at any speed work, energy saving has significant effect.Advantages of soft start:1, the output torque of the motor can meet the requirements of the starting torque of the mechanical system, ensure smooth acceleration, smooth transition, and avoid the impact of destructive torque;2, the starting current to meet the requirements of the motor capacity, to avoid motor heating, causing insulation damage or burnout;3, make the starting current to meet the grid power quality related standards requirements, reduce voltage sag amplitude, reduce the higher harmonic content.

Q: I have an 8 gpm pump at a depth of 170 ft, I am pumping the water 2000 ft in a 1 1/4 inch line. I need to know how many gallons per minute I am getting.: Use the Bernoulli equation, aka mechanical energy balance.

Q: Im looking at putting a little cabin on my property for hunting. i have a 200 gallon under ground water tank for fresh water. I'm needing a pump to run water into the cabin for a sink toilet and possibly a shower. does anyone know what style pump i will need so that it does not constantly build up pressure when not in use that way i don't burn it up.: The way wells work is there's a pump at the bottom. It pumps water into a holding tank that has a diaphragm separating water from an air charge. There's also a pressure sensor switch that kicks the pump on when the pressure in the water tank drops below 40 PSI and shuts it off when it reaches 60 PSI. Well water systems don't just run the pump constantly, or they would burn up. What you want to do is use your storage tank as a source. Pump that into a smaller holding tank from a well water system so that when you run the water you run it from the pressure in the holding tank. When the pressure is low enough the main tank pump will pump up the pressure in the holding tank back to 60 PSI and shut off again. It's well worth it to make sure you don't have leaks. Otherwise your main tank will end up empty and the pump will run on and on. Which is another thing you have to watch for. You can install a float level switch so that if the water in the main tank drops below a certain level it shuts the pump off. AND you can also have it switch a warning light on so you know when the big tank is empty. Hope this helps. '')

Q: Van died on the road. It wants to turn over, but it won't start. I had it towed to Firestone. They're telling me that it needs a whole list of stuff. I ask them, quot;What does it need to just get it running?They say, quot;A new timing belt, water pump, thermostat, and coolant flush.quot;If the timing belt is indeed broken, I know that it will need to be replaced. And, probably the water pump, too. But, what is the importance of the thermostat and coolant flush? Will the car not run if I don't have a thermostat? Can't I just put Engine Coolant in and not have to quot;flushwhatever is supposed to be flushed?Thank you in advance for your help.: It sounds to me like the water pump broke apart, and destroyed the timing belt. The thermostat has wax inside it to control when it opens and closes, so if it overheated there's a good chance the wax leaked out, and the thermostat will no longer open when it should, causing further overheating. As for the flush, they probably want to make sure there are no broken pieces of water pump in there that will cause further damage. As for having your vehicle serviced by Firestone. Ugh:-( I too would be worried about valve to piston contact when the belt broke, but I'm not sure offhand if that's an interference engine or not. I do however know (slightly off topic), from my time as a Dodge tech, that they had a silent recall on the 3.0L heads: If they happened to have them off for any reason, they would cut a small groove in the top of the valve guides with a special tool, and install a snap ring to prevent the guides from sliding down into the runners.

Q: I have a refrigerator that has the built in water dispenser and ice maker but it is in a location that does not have a water source, i would like to set up water tank to pump into the fridge but not sure what type of pump or system is needed to accomplish this i know the fridge does not have one built in, it needs the line pressure to circulate the water.any help would be great, thank you: A refrigerator including a freezer compartment containing an automatic icemaker and a fresh food compartment containing a water reservoir and a diaphragm pump driven by the ice ejecting means forming part of the icemaker for transferring measured quantities of water to the icemaker.

Q: i have a 1991 Jeep Cherokee, started overheating last week, i flushed out the radiator with water, i replaced the thermostat, overheated again, i felt the top radiator hose it was cold. so i replaced the water pump. still overheated. every time i drain the system when i refill it i had red to fill the radiator and reservoir, leave the radiator cap off, then start the engine and turn the heat on max, the radiator burps the air bubble out, then the coolant level in the radiator starts going up and down, my thermostat is rated at 195, when the guage hits 210 hot coolant sprays out of the radiator, but the top radiator hose is cold, what am i doing wrong? is there air still trapped in that top radiator hose?: id say its the radiator after all what ya replaced. have it checked out at a shop. before ya do though ya might do a complete flush of the motor and the cooling system. might be a blockage in a water jacket in the motor. ya can buy the flush kit at any parts store, its simply a T that ya splice into on of the heater core hoses,hook up a water hose,turn heater on, and wait with the engine running. if theres any blockage it will spit and sputter till its pushed out with the water pressure. let it idle till clear water comes out then drain and add coolant. try this first with water only and if it doesnt solve your problem id say ya need a radiator.

Q: im looking at a 87 bmw 325 and the only thing wrong with it is the water pump and cosmetic stuff.. its a cheap deal and i want to know if i could replace it with very little experience under the hood. rate it from 1 to 10.. 1 being as easy as changing your oil and 10 being i would probably have to take it to a mechanic..or jus let me know what you think.: 10 The Space Between Your timing Belt And Engine Block MAke It Extemely Difficult To Get To Your Water Pump.
