Q:I posted this earlier but nobody really answered my question . if my water pump is clearly on the serpentine belt I t need to replace the timing chain to get to it correct? The bolts holding the pump in are around it near the timing chain cover but they don't look like they are inside it. the pump is clearly driven by the serpentine so should I be fine not removing my timing belt to fix the pump? its leaking. Also I know you should replace the timing chain+tensioner but I inspected the chain 400 miles ago its properly tensioned the belt is in good condition its a chain it will last the life of the car its not the cheap belts.

If you can change the pump without removing the timing belt then go for it, you are lucky. I don't replace the tensioner unless it needs to be replaced, usually they last a long time. I replace the timing belts every 60,000 miles, but usually you can go to 80,000 maximum but I don't like to take it to the last minute, not safe.

Q:Hi, what is the difference between an Air pump and a Water pump. What are the functions of each? Does a tank filter come with an air pump? Is an Air pump or Water pump required?

If you have a water pump filter that hangs on the side of the tank you do not need an air pump alhtough I would have both. The water gets oxygen from being circulated. An air pump usually comes with a starter tank along with a air stone. This pump puts oxygen into the water for the fish which should be 1 fish per galllon.

Q:What is the water pump population pre rotation, what harm?

Is the entrance of water flow in the formation of complex turbulent flow, flow direction, shock, vibration, easy to damage the front entrance device, such as vane impeller, shaft sleeve, sealing element. In order to prevent the emergence of the pre swirl phenomenon, usually the design will inlet than outlet diameter, try to make the entrance flow in laminar flow, according to streamline our design, in order to protect the safety and prolong the service life of equipment.

Q:I had my timing belt replaced @ 80k (now have 138k) and was told by new mechanic that the water pump was not replaced then. Do I need to have pump replaced? What will happen if I don't? Thx

water pump is usually replaced with the timing belt since it is easiest to get to when you are doing the timing belt. your water pump may go out on you tomorrow or last for another 300k miles, who knows. but with it not having been changed, you are still riding on a pump with 138k on it. lots of miles on that impeller. if it lasts, just have it changed next timing belt...which I would do @ around 160k miles ~ 80k is about right for a timing belt to last. civic water pumps are cheap...as are the timing belts.

Q:I have a 1998 ford taurus. It started to over heat so i turned on the heater full blast and it didn't get hot. so i put antifreeze in it and i turned it on and it seemed ok but it started to over heat again and the tank for the antifreeze looked like the cap was going to pop off. I was just down the road from my house so i thought if i drove slow i could make it home and it turned on ok but when i put it in drive it stalled. Does this mean its the water pump??????

sounds like Low water level and a possible head gasket failure from over heating!( low water levels do this) you may? be very lucky and simply have a stuck thermostat or faulty filler cap. ( keeps system pressures correct ) try replacing filler cap as very cheap, also before doing so run engine with full water cooling system with cap off for a minute or two and have somebody rev the engine a few times. we should!! see some water flow across the filler section under filler cap. this will be sign the water pump is working. no flow is possible pump failure. in order of likely hood will be 1) head gasket failure 2) water pump failure 3) filler cap failure.

Q:It stops and every few minutes and when it stops, it sounds like water is running.

Ok lets go down the check list. 1) Is your cut off switch working good? Turning on and off at proper set pressure. (I don't know what you may have yours adjusted to. Mine is on at 70 off at 95.) 2) Is your expansion tank (or pressure tank) water logged? Knock on it. Does it sound full or partially full. Full is bad. You will need to shut off the water pump, close off any outgoing ports to the rest of the house, open the drain valve nearest that tank, and press your finger into the shraider valve at the top (the thing that looks like a tire stem valve). Drain the tank only. Then turn the water back on. 3) Do you have water softeners hooked up? Listen closely to the discharge tube. (this may be where it is coming from). IF you hear a leaking it is because the valve spring inside and washers need to be replaced. 4) do you have any other whole house filters? If so check the discharge tubes of them. 5) Do you have a reverse osmosis filter? IF so this is supposed to drain and you will hear it constantly. 6) Look for any water puddles 7) IF all these fail, then replace your water pump.

Q:I recently got the water pump replaced on a 99 Oldsmobile Intrigue GL (3.5L V6), and ever since the temperature gage seems to be running higher...between half way and the 3rd line, where before it was replaced it never got above the second line. It is doing this when I slow down and stop at lights. Once I get going the temperature does drop. Is this normal, or did they do something wrong?

It means the fan isn't working. No air is going through the radiator at low speeds.

Q:ok water can't sucked up more than 10 M height in normal atmospheric pressure some well s are deep more than 10 M even some water aquifers are deep more than 200 m what are technologies used to pump water to ground level BQ- how is crude oil pumped from far deep oil wells (some offshore oil platform pump oil from more than 2000 m deep ocean and another several hundred meters deep from sea beds )

WELL CRUDE OIL ARE UNDER PRESSURE ALREADY. WELL OIL BURST OUT. SOMETIME BLASTED. SUBMERSIBLE PUMPS ARE BETTER OPTION, IF REQUIRED. STORAGE OIL CAN BE TRANSPORTE/MOVE BY USING CENTRIFUGAL PUMPS.

Q:I suddenly have this rattle noise whenever the engine is running but it diminishes with speed. It almost sounds like spark knock but spark knock would get worse at speed. It could be the water pump. Would a water pump get louder with speed, or go away as this does? I feel a tiny bit of in-out motion in the shaft but not side to side. Car is a Geo Metro and does have hydraulic lifters.

check your belt tentioner , ten-shun er. the computer keeps telling me i spelled it wrong

Q:I have a pump connected to a lake, that I use to water garden. I changed the line into the lake as it had a air leak and lost it.'s prime.I have filled water back into the tank and lines .several times. And it hasn't caught it's prime. It is a year old pump that came with it's own tank.When I am doing all this I leave the tap end closed.I'm pretty sure that all is tight and not leaking.The line into the water is only about 5ft deep

Put a check valve in the input line to the pump, under the water line. Then poor water down the pump inlet line. If you used a positive displacement pump, you would not need to prime.
