Q: I have a 1999 Mercury Grand Marquis vehicle. How do you know when the water pump is going. Is their any particular noise I should be hearing.: There is no noise associated with a water pump going out that I am aware of other than the engine exploding due to excessive heat. The dash guages; especially the engine temp guage, will give you a clue as to a cooling problem, whcih is what the water pump is for. The water pump prevents the engine block from overheating. When the pump fails, the engine overheats and will either shut down, or the engine will burn out. The best way to tell is to monitor the temp guage. If the engine is running hot, it either the water pump, lack of water in the cooling system, or Thermostat failure. Best to have a mechanic check it out. Cheers!

Q: i used my water fountain pump for the first time yesterday and I've had it for 10 years and i used it yesterday it worked with the water and everything was fine!then the next day i wanted to turn it on , it went on it started vibrating but it wasn't pumpingwhen i had it on the other day the water was dirty but it was workingi cleaned it the filtershould i put vinegar to clean it ?and what else should i do!??? Help :#92;thank you!: Debris is probably blocking the impeller ,a wheel that spins inside the pump,and moves the water through,you might have to take it in for servicing to a repair shop,if you aren't mechanically inclined to do it yourself.leaf litter,or a twig can get inside the intake port and wedge itself in the wheel,and keep it from working ,try backflushing the pump,forcing water the opposite direction through,and see if this dislodges the blockage first,then if no luck,you'll have to dismantle it to get the blockage out Make sure you handle the pump carefully.if all else fails,you could try whacking it with a hammer,and see if that jolts it free.It is pretty old now,and may be just time to get a new one,10 years is a good life span for one of these pumps.

Q: how much is it to replace timing belt and water pump on a Chrysler voyager 2002?????: Two engines were available in the 2002 Voyager - a 2.4L 4 cylinder engine and a 3.3L V6 engine. The 4 cylinder was timing belt driven but the V6 uses a timing chain with no set replacement interval. Replacing the timing belt and water pump in the 4 cylinder is going to be $500-$850.

Q: Our water pump was really warm/hot to the touch, our hot water was more warm than hot, and wouldnt heat up enough to get hot, and it wouldn't turn off. (like when it starts up when you turn on the water,it just kept going,and wouldn't stop) so, because it was hot, and going constantly, we didn't want it to explode, or burn out, so we turned it off, and now I'm hoping that when we turn it back on after it cools, that it'll go back to turning on/off intermittently, instead of constantly. So, after it cools down, will it go back to normal, instead of just constantly going??!?: I assume you have a water well pump. The experience I have had, is it will come back on once the thermal safety switch cools down. However, I think you still have work here to do because each time this happens, you are shortening the life of your pump. First you need to determine why it ran hot to begin with. Could be lots of reasons, but just to name a few. -Is your water tank in good shape, with the correct air pressure? -Is the tank waterlogged, too old or leaking? -Any leaks in the service in or to the house? -Is your contact switch working properly, clean contacts, good wire, good connections, breaker etc.? -Is there water running somewhere your not aware of? -Last but not least, the check valve and foot valve leading to the well could also be defective. Just my opinion, I hope this helps to get you thinking. Good luck; flip;

Q: replaced one themostat, disconected lower unit twice look at the water pump everything looks fine but when lower unit was reconnected water pump would not work. not sure if asembled it wrong or forgot to d somthing. can someone help.: You miss aligned the Pick UP tube with the lower unit, drop the unit, and watch from the bottom to make sure the hose hits the PICK UP tube !

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?: This universal table is necessary, there is an insulation resistance meter, with some 8 six angle screws, as well as a common pump mechanical seal, you can also enter some of the water pump cable

Q: Where can I get a water pump housing for a 1987 Dodge Dakota, A junk yard?: Besides finding one at a junk yard you could try a Dodge dealer too. Your generation Dakota was made by Dodge until 1996 and if your '87 Dakota has an engine that happens to share a compatible water pump housing design with any '96 model's pump design then you might have some luck. Manufacturers must make replacement parts for their vehicles for 15 years after the model is released - meaning the 1996 Dakota parts should still be available at Dodge dealers. Good luck.

Q: What is the easiest way to remove a water pump?: drain radiator. remove both 21mm motor mount bolts from subframe (front and rear). drain radiator. remove overflow/washer bottle. remove drive belt. remove 8mm bolt that hold lower watertube to front cover. remove lower water tube from water pump. remove heater hoses from water pump. slightly lift engine with floor jack. remove water pump pully. remove water pump. if you still cant get it you will need to remove the 4 studs that go through the water pump. now its just that easy to do

Q: 2 pumps in parallel, lift the same, the pump head is not stacked; 2 pumps in series, the same flow, pump head is not superimposed?.: 2 pumps parallel, lift the same, pump head is not stacked?;Answer: the head can not be superimposed, that is, a lift and a pump, but the pumping speed (flow) is two times a taiwan.2 pumps in series, the same flow, pump head is not stacked?.Answer: the head can be superimposed, that is, the pump head is two times as much as a pump, but the pump speed is the same as that of a pump.

Q: i drove up a hill which was about a mile and when i got up the hill i drove anther half a mile to my location and as soon as i tuned my car off i notice coolant leak for the reservoir tank and being dumb i took the cap off off and i think you know so i drove it home after letting it return to a lower temp and it didn't run hot it just raised 2 line above the middle marker and i ran it today just to idle and refilled the tank and let it run it didn't leak but the Serpentine belt made a noise not loud but noticeable (could this be a bad water pump and i flushed my radiator before they swapped engine out which was not long ago) the current engine is used and run fine with power and pep: water on the belt will cause it to slip and squeak or squeal if the water pump is failing the it woukd be overheating all the time and or leaking water and or be noisy due to bearings failing
