Q: What is the current of the pump when it is started?: When the motor starts, the rotor changes from a prohibited state to a rotating state, requiring a great torque, and the current must increase. When the pump starts, because there is water, it is started with load, and the current will be greater.

Q: how much is it to replace timing belt and water pump on a Chrysler voyager 2002?????: Timing belt can be be anywhere from $200 to $400,but make sure a pro does it beaches if it's put on wrong and off time it can mess up your engine and that would be in the thous..this happened to me.. Water pump idk

Q: Domestic pump automatic shut off the water, but also turn around, stop what happened?: What should have Water Leakage place, check all the toilet faucet is Water Leakage, Water Leakage, water heater and so on, if no problem, to check the pump, which has a check valve, when the valve is broken, can not maintain the pressure, there will be the phenomenon

Q: When I buy submersible pump, the other party did not inform is the aluminum submersible pump, water pump factory production of aluminum submersible pump illegal? Is it against the law to sell the pump to the pump without informing me?: When buying, if you ask for a copper wire or a wire, and don't answer you, it's against the principle of good faith. On the contrary, if you did not ask to buy the water pump with aluminum core, then there is no violation. Because the country does not have any laws and regulations prohibiting the production of aluminum core wire motor, naturally there is no aluminum wire motor as a fake and shoddy products, there is no pre notice obligations.In fact, the aluminum core motor is good, and the price is low, especially in the dry environment of small and medium-sized motors, with good performance. Only used in submersible pumps, because aluminum is easier to damp than copper wire, due to bacteria and other corrosion, and its life is sometimes less than copper wire. But the water pump, aluminum often needs to rewind coil, because of a small submersible pump motor is not good around general scrap.

Q: I need instructions on taking the old one out and replacing it with a new one. Photos will be helpful: Water Pump RemovalRemoval: Disconnect battery ground cable and drain coolant from engine. Loosen water pump idler pulley bolt and remove belt from water pump pulley. Remove water pump inlet tube. Remove three water pump retaining bolts and water pump, Fig. 16. Installation: Clean both gasket mating surfaces on water pump and cylinder block. Install three water pump retaining bolts and tighten to 20-30 N-m (15-22 ft-lbs). Connect water pump inlet tube on water pump. Install water pump belt on pulley and adjust tension to specification. Connect battery ground cable. Replace engine coolant. Operate engine until normal operating temperature is reached. Check for leaks and recheck coolant level. Couldn't get the picure but this should help, the pump is located on the backside of the engine, just be carefull, this engine is really easy to get the pulley on backwards then the belt won't line up right.

Q: Yang Chengtai big, the pump power is too small, the water pump will be bad?: Related to water pump structure, when the pump head is higher than the rated pump head, the current will increase, the water discharged from the pump impeller, back to the inlet of water from between the impeller and the casing exceeds the rated value, if it is a high lift pump, clearance between the impeller and the casing is small, the water pump current increases with increasing lift, current too much faster than the rated value, the motor will burn; if it is a low lift pump design, when the clearance between the impeller and the casing of the strict requirements, and even some of the water pump, the outlet is blocked, the pump will not burn. The drinking water pump used on the table, generally used non-toxic latex diaphragm pump, the head is too much, will damage the diaphragm part, the motor because the circuit has protection, the motor is not easy to damage. Generally do not risk good, according to the actual situation, select the appropriate lift, suction pump.Yang Chengtai large! If the pump power is too small! The pump will break! But not necessarily bad, mainly determined by the pump structure.

Q: Ok, simple question, on a 1992 Jeep Cherokee 4.0. The water pump sucks water (not push) through the heater core correct? So the flow of water goes from the block, through the heater core, into the water pump, right?: The heater middle is placed on the passenger edge on the firewall. From the water pump there'll be 2 small strains going into the black container on the firewall. The heater middle is interior the container. you have gotten a undesirable radiator hose. this is the extra value-effective restoration.If it replaced into the water pump, your automobile could over warmth in minutes. the warmth interior the automobile would desire to be from a vent door caught open interior the heater container.

Q: its a honda accord 1991 Lx my car started overheating only when i stop when i go it doesnt overheat what should i check like the water pump: chances are your radiator cooling fan is not working,could be the cooling fan switch,bad fan motor,or relay

Q: i have a water leak near the water pump in my 1990 cadillac deville i replaced the water pump but it was remanufactured and a pipe on the back of the water pump can it be a heater core or should i buy a brand new one p.s. water leaks after it passes the radiator: this is why I do not buy remanufactured pumps, it is best to buy a new water pump if you can, it will last the lifetime of the car pretty much, remanufactured for what ever reason the water pumps just did not do the job, and I know my mechanic got tired of putting one on, only to have to take it off because it leaked, make sure the water pump is the problem though.

Q: It hasnt rain in quite a while, but I havent had any problems with the water or pressure, but it seems like the pump is always quot;onquot;. I purchased this house almost a year ago, never had a well, so I now very little about it. I moved in December, rain season here in NC, and remember the pump going on and off, now its constantly running, Is it normal for the pump to be running that much? any websites to read up on how a water well works?thanks: Sounds like you have a holding tank problem. Check to see if it is leaking air. Or you could have a busted pipe somewhere, you could cut the water off in the house but not at the pump to see if it continues. If so the problem is at the well, if the problem stops after the tank refills you have a busted pipe between the pump and the house.
