Q: can't get the pulleys to line up I know I have a mid 70's 400 and the water pump is later than 1969 but I can't find a pulley that works every one is about a half inch off I bought a aftermarket set of underdrive pulley's from march performance and still the same problem the water pump is a half inch off there was no long or short water pump right they are all the same lenght right??? The only difference I know of is that pre 1968 the pumps have a 8 bolt design and after they have a 11 bolt design is that right???: did you happen to loose the aluminum spacer between the water pump output shaft, and the fan pulley?

Q: model # gg9002b serial # 65x626092 what year is it and what is the water pump number: try okorder .

Q: One month ago, mechanics replaced water pump for my car, 04 dodge stratus, 100000 miles. When I went to get the car, there was big noise coming out from engine. The mechanics told me it was because of sediment in auto oil system and he show me some sediment he took out. I know little about car so I thought he was right. But now the noise changed and engine light came on. I went to firestone to check it. The report said timing jump and cranked. The second day the engine died totally. And I went to another two mechanics. They said the previous one who replaced the water pump did something wrong to timing chain. But that mechanics didn't admit it. What can I do?: You're on thin ice with this, unless you had the timing belt replaced before 90,000 miles. That big noise was the pistons hitting the valves after the timing belt slipped, or more likely, broke from being worn out. When the engine's water pump is driven by the timing belt, the belt must be slacked to get the pump off, then tightened back up after the new pump installation. That old belt couldn't hold up under the tension. It's just bad luck for the mechanic he didn't think to question the age of the timing belt and insist that it be replaced. Of course that would cost a bit more. It will be an uphill battle. You might as well find a used engine if you want this car back on the road. Good luck to you.

Q: does anyone know the proper way to take the lower gearcase off and install a new water pump kit. it is a 1986.: This is a simple repair but I'd recommend that you get a service manual, ether a factory manual or one of the generic Seloc manuals. The key things to do are mark the trim tab so you can put it back in the same position after repairs. Drain the oil. Removing the bolt that is in the hole at the back end of the upper housing, as well as all the obvious Nuts. both above and under the cavitation plate. Put the drive in forward gear, which takes the tension off the shift shaft. Once all the nuts and bolt are loose. Jiggle the drive and it will separate from the upper housing. You now have access to the water pump housing. Remove the housing and pull it up and off the d. Shaft. Inspect fully and account for missing impeller blades. When you re assemble Lube the impeller and put the drive key in place and put the impeller in place. Slide the housing down to the impeller. You can use ether th drive shaft or the propeller to turn the drive shaft in a clockwise direction as you apply pressure on the housing, It should slide down over the impeller. Reassemble in reverse order. Slide the drive shaft up into the upper housing turning the D. shaft using the prop to turn the shaft. Watch the water tube slip into the guide tube. Once it's in place put a couple nuts on then check the gear shift to make sure it goes F-N-R. Bolt up and fill with oil. Good Luck!

Q: can a worn water pump make the car idle high while in park when driven for a long period of time......03 grand prix: The water pump is only an impeller and moves fluid through the engine for the purpose of cooling. With that in mind, no, it should have no effect. Suspect you have a vacuum leak that is causing your high idle, check for a high pitched whistle and when you find it, fix it.

Q: What is the difference between a sewage pump and a clean water pump? Why can't sewage be pumped with clean water?: The clean water pump and the sewage pump are different from the design. It also requires different material. Sewage pump requires material of solid phase friction, acid and alkali corrosion resistance, and other high resistance, and clean water pump can ignore these requirements. In addition, the sewage pump in a large proportion of large solids content of the fluid can also work normally, and clean water pump in the design can not meet the long-term use of this environment requirements.Of course, clean water pump can also be used for sewage, but only temporary measures, and the life expectancy, the effect can not be guaranteed.

Q: and it still runs about every 1/2 hr even if you are not using water. I have no leaks from the pump thought the house so I think the problem is between the house and the well. I can't hear or see any leaks in the elbows in the well. I tried to pull the foot valve up but can't get it out. I replaced the pump cause it was worn out and it was running every 15 min. Do I need to set the pressure on the new one it cuts off at 42 and on at 20 psi and what else could cause it to run when it shouldn't? I know I should call a plumber, but haven't worked in months and can not afford one.: bleed air out possible leak between house and pump or pump and water either way sucks sorry ive pulled my fair share of pumps old farmboy its bleeding off somewhere thats the question sorry cant help find where look for wet or start pulling pipe out of ground sucks wil need a few friends

Q: Help?Water is to be pumped to the top of a skyscraper. If the pump can create a gauge pressure (pressure above atmospheric pressure) of 8.50E+5 Pa, what is the height of the tallest building that it can service? DATA: g=9.8 m/s^2: IF the pump can produce a static pressure of 8.5e+5 Pa, then it can support a column of water, h h = P/(rho*g) = 8.5e+5/(1000*9.8) = 86.7 m h = 87m Now, the water will have no velocity, so you can't use it effectively, but that's not what the problem asks!

Q: I am new to saltwater tank, and i what to add a sump to my tank, but I don't know what to add to it. what water pump? do i add the filter to the sump or does the filter stay in the tank.: you do no longer use siphons to flow water to the sump, you employ an overflow and pipes. the point of having the overflow in a tank with a sump is that the pass between the two tanks would be even. while the water is pumped returned to the tank and reaches a definite point that water will then pass returned to the sump. If the capability will fail then the pump will end working, so no water would be moved returned into the tank, no water will overflow returned. the priority with 2 pumps would be that no 2 pumps are comparable. One pump is 2 hundred gallons consistent with hour, the different is 199, next one is 195 regardless of being from an identical authentic line and type. So in case you have a 2 hundred and 199 GPH you will finally end up with the two the tank or the sump spilling after some hours.

Q: the car over heats and I hear the antifreeze boiling and it also leaks a small amount of antifreeze amechanic told me i need a thermostat and a new water pump just looking for second opinion.: Always fix the cheaper thing first. So do the thermostat and see if that fixes the problem. The water pump would have to be very bad to be actually causing an overheating problem. Most pumps will make a lot of noise or leak before they actually stop pumping water.
