Q:My water pump was replaced 3 months ago,but it stopped spraying water yesterday, How do I unclog the intake / Outflow?

its the impeller. flush the motor and see if you get little pieces of rubber (the fins of the impeller). and if you still have a warranty then your dealer should fix it for you. a new impeller cost ten buck so if you want to do the labor it will cost you ten bucks

Q:What are the commonly used tools for repairing water pumps? Mainly for civilian 220V submersible pumps, self-priming pumps. How much is the spare parts ready for use?

Because had done a mechanic, and relates to a pump, not including motor repair, commonly used tools: pliers, pliers, adjustable wrench, wrench, screwdriver, bench drill, multimeter, electric iron, Lamar, hammer, ruler, chisel. Commonly used parts: bearings, impellers, screws, terminals, lubricants and so on.

Q:overheating.it has a new thermostat,radiator is clean.temp stays normal during idle,rises when i start to drive.ac is off when this happens.its a 4.7 dodge durango.can water pump simplyquot;go badquot;without ever leaking?

if it,s circulating then the water pump is doing its job. does the fan kick on? maybe 1 of the hoses is closing up when your driving. usually when the bearing goes bad in the pump it takes the seal out too and starts to leak.

Q:I have a 1997 mercedes 320e and it is leaking very bad. I need a temporary fix for the water pump, so that I can take it to the repair shop that is 10 min. away.

Don't try and don't listen to these idiots telling you to leave the cap off or give it a go. The engine will get hot in much less than 10 minutes and those heads are very lightweight aluminum that don't do well when overheated. Not having pressure in the cooling system is almost as bad as not having water with that engine. The easiest way is to have someone replace the pump on the spot. Otherwise, shell out the $50 for a tow unless you want to risk trashing the engine.

Q:i need to know an estimated cost for changing this cars water pumpthanks..

Too okorder i did this, and by doing so it saved me money, time, and the risk of getting ripped off.

Q:Colleagues, could you explain the principles of operation of the water vane vacuum pump? What range of pressure can one achieve with this type of vacuum pump? If somebody could post a reference to books, app notes, commercial datasheets of such pumps, that would be simply great.

Q:Ok, so if i have an 80 watt solar panel and want to run a 12v dc fan and water pump ONLY when the sun is out or enough light to power them, will i need something like a voltage regulator? I would like to have the panels charge deep cycle 12 v batteries at the same time or when the fan and pump is not running. For instance, i have the panels out and my fan and pump on allowing them to run only on solar as well as charge the batteries. What diagram would i use? I would probably get a charge control for the batteries but more importantly what would i need to regulate the power from the panels? Inverter?

You may have to do some math. The 80 watt panel is only 80 watts at peak sun on a 75°F day at the equator. Chances are you will have something less than 80 watts to work with. But you can add up all the hours of partial sun to get an equivalant number of peak sun hours. An example would be a few hours in the morning and evening at partial power and a couple of hours at solar noon at nearly full power may give you 5 peak sun hours worth of light. 5 psh x 80 w/ps = 400 wh Your supply may have 400 watt hours worth of power per day. You state that the fan is 12v dc but what is the wattage? It could be a little 12v dc fan out of a computer or it could be a huge 12v dc fan out of an RV. What is the power requirements of the water pump? Is it a little 12v dc one for a foot tall decorative fountain or an industial 3 phase pump for a well? To charge the battery you need a voltage 120% higher than the battery voltage. 12v x120%=14.4 v To add up your loads convert them all the use to dc watt hours per day Here is an example to give you an idea of how to play with your numbers: Fan 12vdc x 1.5 A = 18 watts, use this for 5 hours your load would be 18w x 5hr = 90 watt hours Pump 120 vac x 2.5 amps = 300 watts (The AC will need to come from an inverter. The inverter has a certain amount of loss. How good it does the job of converting dc to ac is know as it's efficency. Lets use 90% to be safe) 300 watts / 0.90 = 333.4 watts, use this for 1/2 hour per day 333.4w x 0.5hr = 166.7 watt hours The 90 watt hours + the 167 watt hours = 257 watt hours per day. This would leave about 140 watt hours to put into the battery. Yes it would be best to use a charge controller to protect the battery from overcharging if the pump and fan are off, or from draining the battery too much if the fan or pump stays on.

Q:Domestic pump automatic shut off the water, but also turn around, stop what happened?

Absolutely at the pressure switch, just under pressure. The shell open pressure switch, will see there is a spring, the screw is to adjust the pressure of the ~ ~ ~ try, and I've done a lot.

Q:water pump and thermostat were replaced 18 months ago motors done about 20 hrs since replacement have checked and there are no blockagers in water tube what could be the problem thanks

Sounds to me like your impeller is shot. Just because the water pump was replaced, chances are the impeller wasn't.

Q:Hi, my mechanic said that I need a new water pump. I have a 1994 Dodge Caravan SE. What is involved with the whole changing of a water pump? He said it would cost about $400 to $500 for the whole job. Is that correct? Were is a good place to go get one? I live in Staten Island New York. Is sears a good place for that job? What is installed when they do this job? Belts or what??? I thank you for your time and any help is greatly appreciated. I will be taking my car in this week and will leave a best answer based on the correct information. Thanks again :-)

$400 to $500 seems a bit high...should be closer to about $300.. .. call around to a few repair shops and get some prices...this is a pretty straightforward repair for an auto shop..
