Q:how to change water pump on 1999 cadillac eldorado?
Remember that the water pump is reversed as for removing installing. You tighten to remove it loosen it to install it. Also, it only goes in there 1 way!!!! Do not force it or you will be replacing the crossover which aint cheap. Before removing the old one, look at the new water pump founf the notch or different sized tab, it goes in a certain spot. Look at the old one, make sure to take note of where that tab is sitting in the crossover.
Q:What are the components of a water pump being used in a car and how does it work?
An automotive water pump consists of a steel shaft with an impeller (like a steamboat paddle wheel) on one end and a pulley flange on the other. The shaft spins on bearings located in a cast iron or aluminum housing. The housing has internal passages to allow the water to enter the impeller cavity and exit, often to a tube like structure (part of the housing casting) to which one of the rubber radiator hoses attaches. How it works is simple. Water present in the impeller cavity is confined and pushed to the outlet by the rotating vanes of the impeller. The rotation of the pump is usually driven by a belt powered by a pulley on the engine which turns a second pulley mounted to the pumps pulley flange. The characteristics might include things like, is the pump self priming or is it self lubricating? In an automotive system the answer to both questions is yes. To evaluate a pumps efficiency you would want to set up a test rig where you attach the pumps outlet to a long hose and use it to fill a calibrated container (one gallon, five gallons etc). Then with a stopwatch you can either time how long it takes to fill a gallon container or you can measure the volume of water pumped in a minute. Either way you will get useful information you can use to evaluate the pumps efficiency. You should repeat the above test at different engine RPM's to discover if the pump has peak efficiency (or lack of efficiency) at a particular RPM or range of RPM's. Finally, if you do this experiment for real be sure you add water as fast as you pump it out so you don't over heat the engine and damage it. Have fun.
Q:Would a missing bolt in the water pump make it leak?
A missing bolt can definitely cause it to leak. The water pump needs to be torqued to specs and evenly all the way around to be leak free. Miss a bolt and it won't be sealed properly.
Q:Already changed water pump and still leaking???
hoses that go to the water pump are common parts to leak also or the water outlet gasket/or even the thermostat housing
Q:I have a 1999 wv beetle, I need to change water pump, is there anybody can tell me how?
refer to the repair manual for a guide or visit a shop for help and pay, before you start breaking stuff.
Q:Help replacing water pump?
Replacing a water pump when you don't even know if you're talking about the serpentine belt or not, is not a DIY job.
Q:Water pump for distillation unit?
A small centrifugal pump that has the flowrate designated by the condenser manufacturer. I assume it has a heat exchanger of some type to reject the heat to the air and that would need a designate flow. Anyway, look in any lab supply catalog or web site and they will have many small pumps. You do not need to carefully control the flowrate, so stay away from metering or peristaltic pumps. The pumps may even be made of plastic, that is fine for this application. In my lab, we would just run the water from the tap through the glass condenser and let it drain out to waste. It is wasteful of water, but it sure was much cheaper than buying a pump and heat exchanger.
Q:Electrical design into!!! Is the water pump lamp waterproof?
Not ordinary fluorescent lamp, it is waterproof and explosion-proof fluorescent lamp. And the PE protection line must be added
Q:Pump adapter belongs to the system of fire pool equipment?
Not belong to. According to the specification, fire hydrant system and automatic sprinkler system fire water supply pipe should be installed on the pump adapter, therefore, it belongs to the fire water supply facilities.
Q:I have a water pump question?
What makes you think the water pump is bad? If it has a bad seal/bushing then it will be leaking coolant out of the bottom eyelet on the water pump itself and you would be losing coolant, if its overheating then that could be air trapped in the system and may just need to be flushed or ran for a little bit to circulate the system. I would check these options first but if you want to pressure test it just start the vehicle and squeeze the upper radiator hose to see if there is pressure on the hose. I hope this helps you my friend.
