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: where is water pump tempertuer sensor in ford focus 2002: Water-pumps do not have temperature sensors. They're (temperature sensors) always located in the water-jacket of the hottest part of the engine which is the cylinder head. The water-pump coolant temperature is by far the coolest. It's located to the right of the alternator, a few inches facing forward screwed into the cylinder head. The little manual in the glove compartment will not explain where the coolant temperature sensor is.

Q: I drive a 99vw jetta and the coolant was leaking from it i took it to a repair shop they said the water pump was bad and that the seals on the water pump where bad that was defiantly where the coolant was leaking from. I replaced the water pump and drove my car this weekend no troubles, then this afternoon my coolant light came on and i put coolant in my car and it just started trickling out i called the repair shop they said it may just be a loose hose or clamp, is this true or am i looking at something worse than the water pump that has to be replaced?? or would that issue have already came up when they where looking for where the leak was coming from before it was repaired? please help: The pump may have indeed been bad. Did the shop put on the new pump or did you do it yourself? If it was done by the shop, take it back and make them fix it correctly. You have already paid them for the work. If you did it yourself, it should be fairly easy to spot where the leak is coming from. It is also rare but possible that the pump you put on was bad out of the box from the parts store. Not likely...but slim possibility. Hopefully it is just a loose clamp or hose.

Q: i have a 1993 chevy cavalier z24 3.1 what all do i need to do to get the water pump off and replace it: I believe if you are looking at the motor the water pump will be to your left on top of the motor and to the front. Drain the radiator. There is a big smooth pulley that turns the water pump loosen the 4 10mm bolts, remove the belt the remove the bolts. Under the pulley there will be 5 or 6 8mm bolts remove those, make sure a drain pan is under the pump because there will be some residual coolant in the motor. Scrape the old gasket off of the engine block then reverse the procedures to install the new pump. Make sure you torque the pump to the proper specs so that the pump housing does not distort. You can pick up a Chiltons manual for that car a local parts store that can walk you through this in greater detail with pictures. Good Luck

Q: can a failing water pump sound like rattling or popcorn until the motor begins to over heat? the sound is nearthe waterpump. it goes away once the temp starts to overheat.the temp will get near redline then go down to normal and then start creeping up again. thanks for any replies.: Yes it can! I am curious though if what you are hearing is a really bad water pump or spark knock due to excessive heat or possibly a blown head gasket. Remove the belt and shake the pulley on the water pump. If it moves or rattles at all, then it is probably bad. Seems strange that it hasn't tossed the belt off though if it were that bad. Worth looking though, testing is free, parts are not....

Q: 93 Cutless Sierra FWD: It's a major job involving the belt tensioner and quite a few other hard to get at parts as the water pump is buried against the side of the engine compartment. But if you want to try it borrow from the library or buy a Chilton's or any popular service manual and follow the directions (STEP BY STEP),good luck

Q: where would I be able to find information on how to change out a water pump for that specific type of vehicle and year, as well I had got a stain on the body from road work it seems to be cement how could I take spots out without damaging the body's paint? What are my options thanks...: Go to your local auto parts store and pick up a Haynes Repair Manual. Very detailed, and only about $20.

Q: I would like to change the water pump myself but do not have a repair manual.: Do you have the 3.4 or the 3.8? Oh well. No one bothers to give that sort of vital information on here... Don't forget to buy RTV when you go buy the pump. Anyway, the 3.4: To Remove: Drain the cooling system. Remove the drive belt guard if equipped. Loosen the water pump pulley bolts. Remove or disconnect the following: Drive belt. Water pump pulley bolts and pulley. Water pump bolts, pump and gasket. Clean the water pump mating surfaces. To Install: Install or connect the following: Water pump gasket and pump. Water pump bolts. Tighten the water pump bolts to 10 Nm (89 inch lbs.) Water pump pulley and bolt until snug. Drive belt. Tighten the water pump pulley bolts to 25 Nm (18 ft. Lbs.). If removed, install the drive belt guard. Fill the cooling system. Inspect for leaks. For the 3.8: To Remove: Drain the cooling system. Loosen the water pump pulley bolts. Remove or disconnect the following: Drive belt. Water pump pulley bolts. Water pump pulley. Power steering pump and reposition. Water pump bolts. Water pump. Water pump gasket. Clean and inspect the water pump mating surfaces. To Install: Install or connect the following: Water pump gasket. Water pump. Tighten the long water pump bolts to 34 Nm (25 ft. Lbs.) Tighten the short water pump bolts to 22 Nm (16 ft. Lbs.) Water pump pulley. Water pump pulley bolts. Tighten the bolts to 13 Nm (115 inch lbs.) Power steering pump. Drive belt. Fill the cooling system. You're lookin' at eight bolts on the pump in most vehicles your make/model.

Q: I have a quot;Rainbow Lifeguard Quiet One 6000external pump that I would like to use on a new chiller for my tank. The pump is rated at a little over 1500 gallons per hour. I'm debating between a couple of chillers, one that has a max flow rate of 1300 gph and another that has a max of 960.I know that you are only supposed to put any valves on the outflow side of the pump and lessening the flow to 1300 from 1500 doesn't seem like it would be that big of a problem, but I was curious it cutting it back to 960 would be hard on the pump in the long run. (I'm leaning towards the bigger chiller as although it may be overkill for my tank, it would let me have a little more water circulation.): ditto to magic

Q: I have a 1999 Volkswagen Passat and the water pump seems to be leaking. The lower radiator hose has been replaced but it still leaks a fairly substantial amount. From what I can tell the pump is still doing its job but I'm losing coolant. Is there a way I can determine if i just need a new gasket or a new pump altogether without ripping the front end off? Any feedback is appreciated.: Replace the pump. While your at it, since the front end (actually the bumper cover) is off, get the timing belt done, with rollers, tensioner, thermostat, and G12 coolant.

Q: we changed the water pump it went bad and there is still a knock in it please help it is running really sluggish: If it has a knock, you may have blown a head gasket, or worse, cracked the block.
