NOTE :3phase dc is completely different with 3phase AC; 3phase DC means 3 pairs of magnetic polarity & sensor-less, power supply the same with common DC pump(two wires: positive and negative). Intelligent program-driving, sensor-less,PCB board outside (main factor that pump can be high-temperature resistant)

Q: can anyone show me the steps on how to remove the water pump on a 1995 dodge intrepid 3.5l engine?: nicely I absolutely have a ninety seven and the water pump became 80.00 put in by me. It has the three.3 V6, extremely straight forward to do oil transformations spark plugs air filter out it really is a o.k. equipped vehicle. replacing the timing belt will be a really stupid theory - that guy is commonplace with no longer some thing about vehicles in any respect. see you later as you stay remote from both.7 litre engine you'd be superb. Mine is now at 165000 miles unique engine/trans I in simple terms replaced the front wheel bearings and struts. Totalling 275.00 - I put in. Then 40.00 for the alignment.

Q: My 2001 300M is behaving oddly. Occasionally it will gradually overheat after I have driven around for 15 or so minutes. Yes, occasionally. I took it to my mechanic who changed the thermostat and hoses. I then drove it on a trip on the interstate and over a mountain (140 miles ) It was fine with no signs of overheating. Then the next day when I drove to work in the city, the stop and go traffic had it overheating near the end of the trip. I've been able to keep it from going in the red by using the heater. After this happened most of the days, but not all, I took it back to the shop. He reported that the fans were working correctly and the only thing he could come up with is a weak water pump. He stated that when it did get hot, he was able to bring the temp down just by rev'ing the engine a little.Does that sound right? Any other ideas and how to test?: The only reason to replace a water-pump on such a new car is if the weep-hole on the bottom of the water-pump in-put shaft casting is leaking. If your upper radiator hose if hot when the dash temperature reached 195 degree's there is nothing wrong with the water-pump. Cooling systems plug when brand X antifreeze is mixed with the standard equipment, long life type. *Did your mechanic do an inexpensive *cooling system pressure test to look for external and internal coolant leaks? Is the radiator filled to the very top when the engine is stone cold? Is the plastic coolant recovery bottle at least 3/4 full when the radiator cap has been removed? Have you checked to see of the electric cooling fans are operating behind the radiator when the dash temperature reaches 205 degrees? It's less expensive to change the thermostat and radiator pressure cap than a non-leaking water-pump. An 11 year old car is do to have the cooling system drained flushed and *cleaned before having Fresh factory recommended ZEREX G-05 antifreeze added.

Q: 1.where is it located and what would I have to remove 1st to get to it. And would I need a torque wrench if so what # would it have to be at when re-installing water pump: 1990 Toyota Celica

Q: Water pump for 98 Venture?: To replace the water pump on the 3.4L Venture calls for 1.3 hours labor (about $130) and the pump is about $30 and it is a good idea to replace the thermostat and flush the cooling system to get maximum life out of the pump and your cooling system about $100 so you would be looking at about $350

Q: I'm only 18 and don't know much about cars, but my car was overheating so me and my boyfriend brought it to a mechanic.They told me it needs a new timing belt and water pump and that alone would be like 1450.. From my research that sounds like bullshit. By the way I drive a 2000 neon, is it THAT hard to work on, or am I being ripped off?: Your water pump is shot, it's not pumping water through out your engine to cool it off. Usually timing belt has to be taken off or loosed to get to the water pump. In that case why not replace the belt along with the water pump. Let's discuss the break down of the labor and parts. 2000 neon timing belt - $50 2000 neon water pump - $80 2000 neon timing bolt package and misc gasket seals - $20 3 hour job to replace the timing belt $50 per hour x 3 = $150 for labor. So you should actually end up paying $300 at most for the job and that's what I usually pay a Joe mechanic down the street at his back yard garage. The $1150 is the profit cut so your getting screwed. Cheer up, when I was little older than you I paid $4000 for timing belt and water pump for my NSX at the dealer.

Q: I installed a new water pump on a Cherokee straight-6 engine, the upper radiator hose is not heating up and the engine is starting to make a funny noise. The thermostat is new and was working fine before. The coolant reservoir is full and no more coolant will drain to radiator / engine. Anyone know why waterpump is not circulating coolant?: is the radiator full enough?

Q: I have a 2002 honda civic with 85k miles the dealer says the timing belt should be replaced. But with the water pump timing belt tensioner also have to be replaced???: I agree with the dealer.It may sound like he is trying to jack up the job but in fact it will save you money and grief in the long run. Getting to those parts is so labor intensive that if you have to go back in later to change the pump or tensioner pulleys it will cost you the same as it did to have the belt changed. The other thing if the pump starts leaking on a new belt you will have to have it replaced again. Whenever I do a timing belt I change everything that is in there. Then I don't have to worry about it.

Q: Why should the pump fill the air before running? What's the reason why the water doesn't go up?: First of all, why should exhaust air, pump suction principle is the rotation of the impeller, pump water inside the throw out, and then let the inlet pipe into a vacuum. Then, under the influence of atmospheric pressure, the water pressure is pumped into the pump. Therefore, if the water is not filled, the sealing of the pump is impossible to pump the air inside the evacuation of high vacuum. In other words, do not fill the water, you can not smoke water. You can hear the noise in the pump when the water bubbles under the bottom vacuumThe water doesn't go up because it doesn't have enough vacuum!The reason 1 is because there is no water filling,2, because your pump and water vertical height higher than the pump itself suction stroke.3., the pipeline resistance is too large (including the pipe diameter is too small, elbow and so on)

Q: 37KW how many contactors does the pump need to start directly?: First of all, you have to see what voltage you use If 380V then current per KW is about 2A, if it is 660V per KW at about 1.1A, then it is the starting current is 3 to 7 times for the starting current, but for the moment, 380V voltage: 37*2=74A 100A on the line, 660V voltage: 37*1.1=40.7A 63A on the line.

Q: I don't want to have to rent or purchase a electric pump to pump the water out of my pool so are there other ways to get the water out besides the obvious (a bucket and alot of people). I am really tight on money so purchasing a device to do the work isn't a real option but I really need to drain the pool without damaging it.: Hey, your idea about buckets and a bunch of friends sounds like fun. Have a pool draining party! Get a case or two of beer, grill some hamburgers. Then everyone in the pool and have fun. Of course tell them to bring their own buckets.
