Q:What is the average life of a water pump?
From my experience the average life expectancy is 7 to 10 yrs depends on usage. Seems like they last longer when used more often. Hope this answers your Q' BIG CHEO
Q:i hear water in my dash board, i know its the water pump pushing water through the heater core, how do i fix?
Have radiator flush done. Low or air in system
Q:water pump running backward?
you have your belt on the opposite side of the water pump pully just gotta switch it around
Q:Why does the water pump in the tank pull out the power supply and then plug it in?
What kind of filter pump? If you don't pump water, there may be a blockage in the foreign body. You can either take a look or fail to reach the level of water it needs
Q:TDH what units are present in the pump parameters?
Answer: TDH stands for single pole double suction horizontal chemical process pump, suitable for conveying clean or containing micro solid particles of ultra low temperature or high temperature liquid medium, is also particularly suitable for conveying strong corrosive medium. All facilities for horizontal installation are available.Mainly used:Petroleum smelting plant, petroleum conveying equipment and pump used in petroleum deep processing devicePump for coal chemical processPumps for water and desalination systemsPumps for fuel coal fired power generation equipmentSewage treatment and environmental protection pumpStructure characteristics:Pump in the horizontal opening, suction and discharge pipeline is located in the lower half of the pump body. The disassembly and replacement of the wearing parts and the replacement of the rotor parts can be performed without disassembly of the pipe.Double suction impeller, high efficiency, good cavitation performance, axial force is basically balanced.Rigid axle shaft and bearing, double end support, small deflection, small vibration, low noise, oil lubrication of rolling bearings with oil ring, constant level oiler automatic control level, and can get automatic compensation, radial thrust ball bearings back-to-back bear residual axial force.The sealing ring of the shell is provided with a stop and a step, and is arranged on the pump body and the pump cover, so that the assembly and disassembly are convenient.
Q:where is the water pump located on a 2001 camaro?
Water pump will be at the front center of the engine usually about 2 behind the fan belt Please be very careful never to allow the vehicle to run low on coolant or serious and expensive engine damage will occur. If in doubt don't drive it until its fixed Take a flashlight and take a good look over the whole engine compartment giving close attention to all the hoses connecting the engine to the radiator its best to find the exact location of the leak and get it fixed.Coolant leaks usually leave a discolored stain so this may help in finding it. Also take a look at the carpet on both front floorpans of the vehicle its possible that the cars heater may have failed and this will leak coolant all over either 1 or both floor pans which can then leak out on to the ground below via a drain hole.
Q:How difficult is it to replace a water pump on a 1990 mercury Grand Marquis?
you can make it even easier by purchasing a hayne's manual for your car when you buy the water pump. you will need it anyway so you can have the proper torque specs and sequence when reinstalling the new water pump. so if you don't have a torque wrench you will need to rent one. the first step of course will be to drain your cooling system. then use masking tape and a sharpie to number any connectors or hoses you have to remove to access the water pump. once the old one is off make sure to clean every trace of gasket material from the mating flange. then when you are ready to reinstall put a thin coat (use you fingers to spread)of rtv silicone to each side of the new gasket this will help hold in place. then here's where you will need the book insert the bolts and tighten them in sequence shown to the proper torque unless you want to chance cracking the new pump housing. on a car this old if it has not already been done now would be a good time to replace hoses (esp. if they are soft) and your thermostat since you've already got the cooling system drained. once everything is reassembled start the engine and begin pouring in the new coolant, if there are any bleed screws open these it's very important to get all the air out of the system if there are no bleed screws you can leave the cap off the radiator or expansion tank (you'll need to anyway) since one you think its filled when the thermostat opens its all gonna drain down and you'll have to top it off again. here is a good time to pay attention as it approaches normal operating temp be ready to start pouring as soon as the level starts to drop that will help keep more air from getting in. any questions feel free to e-mail me
Q:What is the aprox. GPM of a 1HP water pump?
The capacity will be limited by the pressure drop. Assume 15-40 GPM depending on the length of the 1 hose. This is provided that the 1 is then split into four 1/2 hoses. Otherwise the flow will be highly restricted by the smaller diameter. The efficiency of a small centrifugal pump is around 50%. The general water pump equation at 50% eff. is HP = GPM psi / 860. So for one horsepower the GPM = 860 / psi Therefore for 20 psi the flow is 43 GPM, at 40 psi it is 21 GPM , at 60 psi it is 15 GPM
Q:are duralast water pumps any good?
Point blank, ask the folks at Auto Zone where this water-pump was produced. If it was re-manufactured off-shore leave it on their shelves. I trust you knew these Duralast water-pumps are re-manufactured. All AC-Delco starters, alternators and water-pumps are re-manufactured in the USA. Every part inside the reused housings are factory brand new with parts made here in the US.
Q:how much to replace water pump and timing belt on a PT Cruiser?
A suggestion. If your car is around 70,000 to 100,000 miles then you should change the timing belt. If it breaks, it will leave you stranded, and cost you more because the engine may be damaged. (girlfriend ignored the warning and it cost her $1000 in engine parts - I was the free labor!) Because the timing belt runs the water pump, most mechanics recommend changing the water pump at the same time, the water pump does not cost that much more. Parts and labor for this cost about $700 to $1000, sometimes it costs a bit more because the idler pulley is worn and must be replaced also. As for your leak, it would be best to have the cooling system pressure tested to find the spot of the leak. If its sometime other than the water pump, you'll be glad you found it early. Good luck.
